Setup and Configuration Operations

This section describes setup and configuration operations, including modifying LAN polling mechanisms and timeouts for the network management PC, and enabling or disabling the polling of specified hubs or all hubs within a submap.

Cisco Hub/Ring Manager Application Setup

Use the Cisco Hub/Ring Manager Application Setup dialog box to change parameters that control LAN polling mechanisms and timeouts for Cisco Hub/Ring Manager applications on the network management PC. You can change these parameters according to the network load and the number of hubs being managed. Local time settings affect hubs designated as local in the Describe dialog box. Remote time settings affect hubs designated as remote in the Describe dialog box. Communications are usually more frequent with local hubs and less frequent with remote hubs in order to prevent network overload and reduce the cost of transmission.

To configure Cisco Hub/Ring Manager parameters, from the Options menu select the Hub/Ring Application Setup command. The Hub/Ring Application Setup dialog box appears. (See Figure 3-1.) The fields of the Hub/Ring Application Setup dialog box are described in Table 3-6. Hubs are designated local or remote in the Location dialog box, which is reached from the Location command button in the Describe dialog box.


Figure 3-1: Hub/Ring Application Setup: Hub Manager Dialog Box




Table  3-6:
Application Setup Fields
Field Description
Number of Local Managed Hubs Displays the current number of hubs in the map that are designated as local (set in the Describe dialog box) and designated as managed (set in the Hub/Ring Object Manager dialog box).
Number of Remote Managed Hubs Displays the current number of hubs in the map that are designated as remote (set in the Describe dialog box) and designated as managed (set in the Hub/Ring Object Manager dialog box).
Total Number of Managed Hubs Displays the current number of hubs in the map that are designated as managed. This value is the sum of the number of local managed hubs and the number of remote managed hubs.
Selected Application Allows you to select an application. Settings for the application appear in the fields on the right.
Common Application Parameters Lists parameters that apply to all three Cisco Hub/Ring Manager polling applications.
Local Time-out Shows the time (in seconds) that the management station waits for a hub response message through the LAN interface. When the timeout is exceeded and a response message has not arrived from the hub, the management station either tries to resend the message or records a LAN communication error. The value should be increased in a loaded LAN.1
Remote Time-out Shows the time (in seconds) that the management station waits for a hub response message through the LAN interface. When the time-out is exceeded, and a response message has not arrived from the hub, the management station either tries to resend the message or records a LAN communication error. The number should be increased in a remote network.2
Recommended Displays the recommended hub-response timeout setting. Click the arrow to copy this value into the Current field. This value cannot be edited.
Current Displays the current hub-response timeout setting. Click the arrow to copy the Recommended value into this field.

1 The local timeout value affects all hubs designated local. Cisco Systems suggests using the timeout in the Recommended field, which is calculated as (number of local hubs + 1) x (maximum time between polls under Hub Manager and Ring Manager) x 3.
2 The remote timeout value affects all hubs designated remote. Cisco Systems suggests using the timeout in the Recommended field, which is calculated as (number of remote hubs + 1) x (maximum time between polls under Hub Manager and Ring Manager) x 3.

Hub Manager Parameters

When you select Hub Manager from the Selected Application list box, the corresponding settings appear in the fields to the right, as shown in Figure 3-1 and listed in Table 3-7.


Table  3-7: Hub Manager Local and Remote Polling Fields
Field Description
Local Time Between Polls Displays the time (in ms) between two consecutive Hub/Ring Manager pollings in the LAN. This value should reflect the number of hubs in the network. The default value is 3000. The recommended values are:

  • For one hub--3500 ms

  • For three hubs--2500 ms

  • For 10 or more hubs--1000 ms

The local polling time should be significantly more frequent than the remote polling time.1

Remote Time Between Polls Displays the time (in seconds) between two consecutive Hub/Ring Manager pollings in the LAN. The default value is 7 seconds.1

1 Decreasing this number enables the management station to reflect changes in the hubs faster, but also increases the network load.

Ring Manager Parameters

When you select Ring Manager from the Selected Application list box, the fields shown in Figure 3-2 and listed in Table 3-8 appear.


Figure 3-2: Hub-Ring Application Setup: Ring Manager Dialog Box




Table  3-8:
Ring Manager Local and Remote Polling Fields
Field Description
Local Time Between Polls Indicates the time (in ms) between two consecutive Ring Manager pollings in the LAN. This value should reflect the number of rings in the network. The default value is 3500. The recommended values are:

  • For one ring--3500 ms

  • For three rings--2500 ms

  • For 10 or more rings--1000 ms

The default value is 3500 ms.1

Remote Time Between Polls Indicates the time (in seconds) between two consecutive Ring Manager pollings of remotely managed hubs in the LAN. The default value is 7 seconds.1

1 Decreasing this number enables the management station to more quickly reflect changes on the ring to which the NMS is attached. It also increases the network load. Local and remote polling times affect all hubs designated as local or remote, respectively, in the Router/Hub Location dialog box. Local polling should be significantly more frequent than remote polling.

Trap Manager Parameters

When you select Trap Manager from the Selected Application list box, the corresponding settings appear in the fields to the right, as shown in Figure 3-3 and listed in Table 3-9.


Figure 3-3: Hub/Ring Application Setup: Trap Manager Dialog Box




Table  3-9:
Trap Manager Polling and Directory Status Fields
Field Description
Enable Traps Time Between Polls Indicates the time (in seconds) between two consecutive Trap Manager polls that verify that the SNMP agent's trapping mechanism is active. This parameter should be modified only by experienced users. The default value is 30.
Logged Traps Time Between Polls Indicates the time (in seconds) between two consecutive Trap Manager polls for buffered traps. This parameter should be modified only by experienced users. The default value is 300.
Trap Config. Directory Contains the trap configuration files. You can specify a new directory or use the default.

Hub/Ring Object Manager

From the Hub/Ring Object Manager dialog box, you can perform selective management of specified hubs or all hubs in a submap.

To open the Hub/Ring Object Manager dialog box, from the Options menu select Hub/Ring Object Manager. The dialog box appears, as shown in Figure 3-4.


Figure 3-4: Hub/Ring Object Manager Dialog Box




Note An asterisk (*) before an object name in the Hub/Ring Object Manager dialog box indicates that the object is currently managed by Cisco Hub/Ring Manager for Windows.

Submap objects and hub objects that are unmanaged remain unmanaged, even in subsequent Hub/Ring Manager sessions, until they are set to managed.

If a submap is unmanaged, the polling of all applications to all hubs in that submap is disabled. The managed or unmanaged status is not propagated to other submaps in the hierarchy. If you unmanage all hubs in a submap, they are no longer managed; however, all submaps within the submap remain managed.

You can also perform selective management functions in the following way:

Step 1 From your HP OpenView network map, select a submap object, hub, or ring object, then click the right mouse button to display its popup menu.

Step 2 From a submap object, select either Manage Submap or Unmanage Submap.

Step 3 From a hub or ring object, select either Manage Object or Unmanage Object.

Table 3-10 describes the fields in the Hub/Ring Object Manager dialog box.


Table  3-10: Hub/Ring Object Manager Dialog Box Fields
Field Description
Submap Specifies the submap that contains the hubs you want to manage or unmanage.

  • Click the arrow of the Submap field and scroll through the list to select the submap.

  • Click the Manage Submap button (the green octagon) or the Unmanage Submap button (the pale yellow octagon).

Hub Objects

Displays all hub objects included in the specified submap. This parameter allows you to manage or unmanage a specified object.

  • Click the hub name to select it.

  • Click the Manage Object button (the green diamond) or the Unmanage Object button (the pale yellow diamond).

  • To deselect a hub, click its name again.

The functions for managing all hubs in a submap and managing an individual hub can be used together. For example, you might want to disable management of all but one hub in a submap. To do this, first select the submap name and click on the Unmanage Submap button. Next select the name of the object for which you want to enable management, then click on the Manage Object button.

Selective Application Polling

You can choose which Hub/Ring Manager applications are active--that is, which applications should poll selected hubs in the map. In the Control menu, applications that are active have a checkmark next to their names. Each Hub/Ring Manager session starts with all Hub/Ring Manager applications active.

To deactivate an application, perform the following steps:

Step 1 From the Control menu, select the application that you want to disable--Ring Manager, Hub/Ring Trap Manager, or Hub Manager.

Ethernet Manager does not appear in this list, because it polls only when the Ethernet Statistics window is open.


Step 2 From the submenu, select Disable Polling.

The checkmark moves from Enable Polling to Disable Polling to indicate that the application is deactivated. To reenable the application, follow the same procedure and select Enable Polling.


Hub Management Operations

This section describes management operations that apply to both Ethernet and Token Ring hubs.

Asset Management

Use the Asset Management command in the Control menu to view broad configuration information on your router/hub. Asset Management consists of two subcommands: Hub Configuration and Summary File.

Hub Configuration

Use the Hub Configuration command to view a list of hardware and software revisions and the state of all jumpers and DIP switches for each module installed in a selected hub.

To use the Hub Configuration command, perform the following steps:

Step 1 Select a hub object in your network map.

Step 2 From the Control menu, select Asset Management.

Step 3 Select Hub Configuration.

The Hub Configuration window appears.


The items shown in this window depend on the type of hub that is selected and the modules installed in it.


Step 4 To view the jumper and switch settings for a module, click on the box that indicates the slot in which the module is installed. The window expands to show relevant jumper and user settings for all Token Ring or Ethernet modules installed in the hub, as shown in Figure 3-5.


Figure 3-5: Hub Configuration Window



A dash (--) indicates that this setting is not available or is irrelevant. An empty jumper setting in the USR box indicates that the user has not overridden the hardware setting.

Table 3-11 describes the fields, command buttons, and other parameters of the Hub Configuration window.


Table  3-11: Hub Configuration Window Fields
Field Description
Hub Name The name of the hub selected in the map.
Hub Type The type of map object, such as router/hub.
HW In the upper right corner, specifies the hardware revision of the router/hub. Under Slot Name, specifies the hardware revision of each hub module. Under each jumper, specifies the jumper's hardware setting.
SW In the upper right corner, specifies the software revision of the router/hub. Under Slot Name, specifies the software revision of each hub module. Under each jumper, specifies the user's software override setting.

File

The File... command opens the Save As dialog box, allowing you to save configuration information for all hubs in the map to a file.

Attaching Devices to the Router/Hub

The Attachment command under the HP OpenView Control menu displays the Hub Attachment dialog box. Use the Hub Attachment dialog box to associate mapped devices with router/hub ports or to associate the router component with the hub component.

Attachment establishes a graphical connection between LAN nodes and hub ports, and adds a corresponding entry to the HP OpenView database. It enables you to document your network topology by matching devices with hub ports. For example, when you click on a hub port in the Control Panel and select Identify from the popup menu, you see the IP address, MAC address, and map icon name of the attached device.

Attachment also aids in automatic configuration. If you attach the router portion of the router/hub, the Perform command button

in the Check MAC-to-Port Mapping dialog box automatically scans the database for devices attached to hub ports.

Attachment does not change the physical connections between nodes and ports. You can change physical connections only by plugging in and unplugging cables. Attachment also does not enable or disable nodes on the hub; to do that, use the Reconnect and Disconnect commands in the popup menu on the Control Panel.

To open the Hub Attachment dialog box, do one of the following:

The Hub Attachment dialog box appears, as shown in Figure 3-6. Table 3-12 describes the Hub Attachment dialog box fields and command buttons.


Figure 3-6: Hub Attachment Dialog Box




Table  3-12:
Hub Attachment Dialog Box Fields and Command Buttons

Field or Command Button Meaning
Name Name of the object selected in the map.
Type Type of map object, such as PC or router/hub.
Slot number Click on a slot number to display the module installed in that slot. The NMS and hub modules are opened by default, as shown in Figure 3-7. You can move a module display by dragging on its name.
Attach (plus sign) Attaches the selected items.
Detach (minus sign) Detaches the selected items.
Deselect All (X icon) Deselects all ports.
Identify (eyeglasses icon) Opens the Identify Node dialog box. See the "Identify Node" section.
Open (opening folder icon) Opens a new Hub Attachment dialog box for another object without closing the one that is open.

The NMS module in slot 0 and the Ethernet or Token Ring module in slot 1 are displayed automatically, as shown in Figure 3-7 for an Ethernet module.


Figure 3-7: NMS and Hub Module Displays


Slots with gray numbers cannot be opened and indicate one of the following:

If all module numbers are gray, there may be no communication with the hub.

Ports that are not attached have a black symbol consisting of two triangles pointing away from each other. Ports that are attached have a blue symbol consisting of two triangles pointing toward each other. To select a port for attachment, click on the port. The port's symbol changes to green. To deselect the port, click on it again, or click on the Deselect All icon in the Hub Attachment dialog box.

The Hub Attachment dialog box and the module displays associated with it are coded with matching colors, so that you can identify the modules belonging to each hub. These colors do not reflect the status of the port, slot, or hub.

Attaching a Router/Hub Port to a PC

To attach a router/hub port to a PC, perform the following steps:

Step 1 Select the router/hub in the network map and open its Hub Attachment dialog box.

Step 2 Click on the slot to display the module.

Step 3 Click on the port. The port's color changes to green.

Step 4 Select the PC object by clicking on it in the map. If necessary, you can drag the Hub Attachment dialog box and the module displays by their names to uncover the PC object.

Another way to select the PC object is to click on the Open button (opening folder icon) in the router/hub Hub Attachment dialog box. If a device is selected in the map, the Device Attachment dialog box for that device appears. If no device is selected, an Open dialog box appears. Select the device name or type from the lists in this dialog box and click OK. The Device Attachment dialog box appears.


Select the PC from the list in the Device Attachment dialog box, then click on the triangle symbol. The symbol changes to green.


Step 5 Click on the Attach icon in the Hub Attachment dialog box. The port symbol changes to blue.


Note Click on the Attach icon in the Hub Attachment dialog box, not the Device Attachment dialog box.

Step 6 From the Control menu, select Sync. Attachment.

The PC icon on the map now changes color to indicate its status; this change can take up to several minutes, depending on your polling settings. The color coding is shown in Table 3-13.



Note Attached devices do not change color to indicate their status until you perform Sync. Attachment.

If you attach a device to an occupied port, the device that was previously attached is detached automatically.



Note Configure HP OpenView not to poll attached PCs and other non-IP devices.

Attaching the Router to a LAN Segment

For proper operation of Cisco Hub/Ring Manager, the router component of the router/hub must be both physically connected and logically attached to a LAN segment.

In Token Ring environments, the TR port on the router component must be connected to port 1 on the Token Ring (LBM) module (or to port 2 if port 1 is set to EXT mode on a Cisco 2517). The Cisco Hub/Ring Manager package provides a cable for this purpose.

In Ethernet environments, the ETH port on the router component can be connected to any port on the Ethernet (ECM) module. It is usually connected to the nearest port.

Since the router component does not appear in the Hub Attachment dialog box, its TR or ETH port is represented as an ADJ LAN port on the network management processor system (NMS) module in slot 0.

To make this attachment, perform the following steps:

Step 1 Select the router/hub object in the network map and open its Hub Attachment dialog box.

Step 2 Click on slot 0 to display the NMS module.

Step 3 Click on the ADJ LAN port. The port's color changes to green.

Step 4 Click on the slot that holds the hub module.

Step 5 Click on the hub port to which the router component is connected. The port's color changes to green.

Step 6 Click on the Attach icon. Both port symbols change to blue.

Synchronizing Attachments

After you have completed attaching devices, open the Control menu and select Sync. Attachment. The icon on the map for the attached device changes color to indicate its status. This change may take up to several minutes, depending on your polling settings.

Detaching an Object

To detach an object, follow the procedure for attachment, select the items to be detached, and click on the Detach icon. All selected map objects and ports are detached simultaneously.

Color Coding

The color of objects in the network map indicates their status. Table 3-13 describes the meaning of these colors.


Table  3-13: Attached Device Color Code
Color Meaning
Green (normal) The device is working normally and can be reached by SNMP.
Magenta (informational) The device has been disconnected by the user, for example, through the Control Panel.
Yellow (warning) The device is operating, but in a warning state, for example:

  • An Ethernet port is partitioned.

  • A node frequency error has been detected on a Token Ring network.

Red (critical)

Communication has been lost or a severe error has been detected.
Blue (unknown) The status is unknown, because, for example:

  • The device is not attached to any port.

  • The device is off.

  • The device lobe is not plugged in on a Token Ring network.

  • There is no communication with the hub to which the device is attached.

Pale yellow (unmanaged)

The device is unmanaged.

Control Panel

The Control Panel provides a graphical representation of the router/hub and its installed modules. The screen is continuously updated to reflect any changes to the port, LED, or module.

To open the Control Panel, perform the following steps:

Step 1 From your network map, select a router/hub.

Step 2 From the Control menu, select Hub Manager, then select Control Panel.

Alternatively, select the router/hub in the network map, click the right mouse button to display the popup menu, and select Control Panel.

Figure 3-8 shows an example of a router/hub Control Panel.


Figure 3-8: Cisco 2518 Control Panel



From the router/hub Control Panel, you can perform the following functions:

Selecting an Item from the Control Panel

From the Control Panel, you can select an individual port or an entire module. You can also perform other functions by clicking the hot spots shown in dotted boxes. When you click a hot spot, a popup menu appears from which you can apply commands related to the selected item.

Table 3-14 describes Control Panel hot spots and the commands available.

Ring Management Operations

This section discusses Ring Manager commands, windows, and dialog boxes.

All Rings

Use the All Rings window to obtain information about all rings in the network, including a ring's name, ID, status, and number of nodes. In addition, the status bar in the lower right corner displays the current date and time.

If the All Rings window is minimized, double-click on the icon to maximize it. If the window is closed, open it by performing the following steps:

Step 1 From the Control menu, select Ring Manager.

Step 2 Select All Rings.

The All Rings window appears, as shown in Figure 3-9.


Figure 3-9: All Rings Window



Table 3-18 explains the meaning of each color.


Table  3-18: Ring Status Color Code
Line Color Status Meaning
Green Normal The ring is operating normally.
Red Beaconing There is a serious problem on the ring, such as a failure in the cabling system, ring hubs, or circuitry of a node on the ring.

Localize the fault domain by checking the node address of the node that generated the beacon event and the nearest active upstream neighbor (NAUN). The fault lies in the cabling or ring hubs between these two nodes, or within one of the two nodes. Beaconing usually recovers after a fraction of a second.

Red Excessive Errors An isolated error has exceeded the second threshold. This indicates a problem on the ring that is seriously affecting its performance.
Yellow Increasing Errors An isolated error has exceeded the first threshold. This indicates a possible problem on the ring.
Cyan Unknown There is no communication with SNMP agents on the ring.
White Unmanaged All hubs monitoring this ring are unmanaged.

Table 3-19 identifies and describes the fields and components of the All Rings window.


Table  3-19: All Rings Window Fields and Components
Field or Component Description
Ring Name Displays the ring name that you assigned. The ring name is the text you entered in the Segment field of the Token Ring Interfaces dialog box reached from the Describe dialog box. If you leave the Segment field blank, Ring Manager uses the Token Ring interface address as the ring name, in the format subnet address_hex ring number (for example, 192.111.3_3F).
Ring ID Shows the ring number in both hexadecimal and decimal format.
Ring Status Indicates the overall ring status at a specified date and time.
Reported by Indicates the hub or entity that supplied the status information.
Nodes # Displays the number of nodes currently in the ring (Active Monitor + Standby Monitors).
Status Bar Shows the current date and time in the lower right corner of the dialog box.
Ring Monitor (binoculars icon) Opens the Ring Monitor window for the current ring. (See the "Ring Monitor" section.)
Ring Configuration (network icon) Opens the Ring Configuration window for the current ring. (See the "Ring Configuration" section.)
Event Filter (joined stations) Opens the Event Filter dialog box. (See the "Event Filter" section.)
Ring Events (bell icon) Opens the Ring Events window for the current ring. (See the "Ring Events" section.)

MAC-to-Port Mapping

In some cases you may need to verify that information such as a device's name, MAC address, and location in the hub are consistent. You can view these values in the Check MAC-to-Port Mapping dialog box. You can also use the Check MAC-to-Port Mapping dialog box to correct inconsistencies, such as when the address of a device that was entered in the Describe dialog box does not match the address of the same device as determined by Ring Manager.

Ring Manager's ability to display information in the Check MAC-to-Port Mapping dialog box can be limited or unsuccessful, depending on the hub's configuration. You can display MAC-to-port mapping information only on rings where none of the active ports are set to extension mode.

To open the Check MAC-to-Port Mapping dialog box, shown in Figure 3-10, do one of the following:


Figure 3-10: Check MAC-to-Port Mapping Dialog Box



When you first view the Check MAC-to-Port Mapping dialog box, the list of mappings is empty. To display MAC-to-port mapping information, click Perform. If any inconsistencies appear, such as address information in the Describe dialog box not matching what Ring Manager found, a message reports the problem.

To update the database, click the Update Database checkbox, then click Perform. Whenever you update the database, select the Sync. Attachment command from the Control menu to update the Cisco Hub/Ring Manager database with information from the HP OpenView database.

Ring Manager Customization

At times you may want to automate certain Ring Manager functions. For example, you might want Ring Manager to automatically remove nodes if they attempt to enter a locked ring. The Customization dialog box allows you to set up this kind of automated action. The preferences that you set up apply to all Cisco router/hub SNMP agents that manage Token Ring ports in the network.

To display the Customization dialog box, perform the following steps:

Step 1 From the Control menu, select Ring Manager.

Step 2 Select Customization.

The Ring Manager Customization dialog box appears, as shown in Figure 3-12.


Figure 3-12: Ring Manager Customization Dialog Box



Table 3-22 describes the fields in the Ring Manager Customization dialog box.


Table  3-22: Ring Manager Customization Dialog Box Fields
Field Description
Security Auto Removal Removes unauthorized devices from the ring by default. When enabled, Ring Manager automatically removes devices violating security from the ring upon their insertion. A device is considered a security violator when it attempts to insert into a ring whose configuration is locked in the Security dialog box. The default setting is disabled.
Error Auto Removal Removes devices that exceed the isolating error threshold or congestion threshold from the ring. The Error Auto Removal function can be performed by either Ring Manager or the SNMP agent. The default setting is disabled.
Manager Designates Ring Manager to perform the Error Auto Removal function. When enabled, Ring Manager automatically removes devices that exceed the isolating error threshold from the ring. For these stations to be removed, the Ring Manager application must be active (for example, Enable Polling). Devices designated as untouchable in the Ring Security dialog box are not removed.
Agent Designates the SNMP agent to perform the Error Auto Removal function. The SNMP agent continually monitors the ring and issues a command to remove devices that exceed the isolating error threshold or congestion threshold from the ring. The agent continues to remove these stations even when the Ring Manager application is not active (for example, Disable Polling) or when the Hub/Ring Manager PC is powered off. Devices designated as untouchable in the Ring Security dialog box are removed.
Reset Inactive Agents This function should be enabled in networks with a single station running the Ring Manager application to update the agents with changes in a device's status (for example, Allowed, Not Allowed, Monitored, or Not Monitor). This function should not be enabled in networks with multiple stations running Ring Manager. The default setting is enabled.
Always Poll Events When enabled, Ring Manager continually polls agents and logs their data in the events buffer, even when the Ring Events window is closed. Cisco recommends that you enable this function in noisy environments to keep the error counters and event logs up to date. When disabled, Ring Manager polls agents and logs their data in the events buffer only when the Ring Events wndow is open. The default setting is disabled.

Event Filter

Use the Event Filter dialog box to filter events that appear in the Ring Events window.

To open the Event Filter dialog box, perform the following steps:

Step 1 From the Control menu, select Ring Manager.

Table  3-27: Ring Monitor Window Command Buttons
Field or Command Button Description

Ring Status

Displays the ring status at the specified date and time. Ring status is indicated by the color of the ring icon (colored face) as follows:

  • Green--Normal. The ring is operating normally.

  • Dark green--Single station. The reporting agent is the only station on the ring in the managed state.

  • Cyan--Unknown. There is no communication with the agents on the ring.

  • Yellow with a red B--Beaconing. There is a serious problem on the ring. Beaconing can mean a failure in the cabling system or ring hubs, or in the circuitry of a node on the ring. To localize the fault domain, check the node address of the node that generated the beacon event and that of the node's NAUN. The fault lies in the cabling or ring hubs between these two nodes, or within one of the two nodes. Beaconing usually recovers itself after a fraction of a second.

  • Yellow--Increasing errors. An isolated error has exceeded the first threshold, indicating a potential problem.

  • Red--Excessive errors. An isolated error has exceeded the second threshold, indicating a problem on the ring that is seriously affecting its performance.

  • Yellow and white checkerboard--All hubs monitoring this ring are unmanaged.

The face shown in the ring icon changes according to the ring color.

Ring Name Displays the name or ID of the ring. The ring name is set in the Describe dialog box for the ring or discovered by Ring Manager. If Ring Manager discovers a ring, it uses a combination of the subnet address and ring number as the ring name (for example, 192.114.4_3F).
Ring No. (hex/dec) Displays the ring number, as discovered by Ring Manager, in hexadecimal and decimal format.
Active Monitor Displays the MAC address or name of the Active Monitor at the specified time.
Reported By Displays the name of the hub or entity that supplied the status information.
No. of Nodes Displays the number of nodes on the ring (Standby Monitors plus Active Monitor) at the specified time.
Last Beacon Displays the type of the last detected beacon and the nodes between which beaconing was located. Click on the i command button to identify the node.

Errors

Displays the number of errors detected on this ring since the reporting agent was activated, and since the counters were last reset:

  • Beacon--Beacon errors

  • Poll Fail--Poll fail errors

  • Purge--Purge errors

  • Claim--Claim token errors

  • Iso.Trsh--Number of times the threshold for isolating errors was crossed

  • Cong. Trsh--Number of times the congestion threshold was crossed

  • NoIso Tr.--Number of times the threshold for nonisolating errors was crossed

  • No Resp.--Number of no response errors detected on this ring since the reporting agent was activated

Ethernet Manager Parameters

Use Ethernet Manager to set parameters for the graphical displays of network activity shown in the Ethernet Statistics window.

Ethernet Manager provides three functions: Set Threshold Parameters, Set Statistics Graph Scale, and Ethernet Statistics File Management. To modify parameters for one of these functions, from the Control menu, select Ethernet Manager, then select the function. Each function has its own dialog box.

Set Threshold Parameters

The Set Threshold Parameters dialog box, shown in Figure 3-21, defines alert thresholds at the network level for three types of events: receive events, collisions, and frequency alignment errors (FAE). You can set low and high thresholds in frames/sec. The fields in this dialog box are described in Table 3-31.


Figure 3-21: Set Threshold Parameters Dialog Box




Table  3-31:
Set Threshold Parameters Dialog Box Fields

Field Description
Receive Includes all receive events. The default low threshold is 3000 frames/sec and the default high threshold is 7000 frames/sec.
Collisions Includes all collisions. The default low threshold is 1000 frames/sec and the default high threshold is 3000 frames/sec.
FAE Includes all errors except collisions. The default low threshold is 1000 frames/sec and the default high threshold is 3000 frames/sec.

Set Statistics Graph Scale

The Set Statistics Graph Scale dialog box, shown in Figure 3-22, sets the vertical scale for the Ethernet Statistics window in frames/sec. The option buttons in this dialog box are described in Table 3-32.

Dynamic Scale Sets the scale automatically depending on the magnitude of the data.
Fixed Scale Enables you to set the maximum value in the scale yourself, using the horizontal scroll bar. If the number of frames/sec exceeds this value, the graph line in the Ethernet Statistics window is clipped. The largest value permitted is 10,000 frames/sec.

Ethernet Statistics File Management

Graphical information displayed in the Ethernet Statistics window is saved in files for future retrieval. Three files are created, one for each event type, for each port for which a window is open. A file is full after the window has been running for approximately 10 to 15 minutes, and contains approximately 630 bytes of data. Statistical files are in binary format and can be retrieved by selecting a port and an event type in the Ethernet Statistics window, clicking the Freeze Graph command button, and scrolling through the display.

The Ethernet Statistics File Management dialog box, shown in Figure 3-23, is designed for advanced management of statistical files. You do not normally need to change any of the settings in this dialog box, which are described in Table 3-33. Ethernet Manager automatically manages the files and deletes the oldest ones as required.

Caution  Do not use Windows or DOS to delete statistical files from the hard disk. Instead, use the Delete command in this dialog box.

Describe Operations

This section explains Describe operations.

Describe

Use the Describe command to view and modify configuration information about a node or device. For a hub symbol, you can view its name, notepad, physical location, LAN adapter address, network administrator telephone number, segment number, and TCP/IP address.

There are two types of Describe dialog boxes. The Describe dialog box described in this section applies to router/hub objects.

The Router/Hub Describe dialog box, shown in Figure 3-24, appears whenever you do one of the following:


Note If you open the Describe dialog box for the hub object in a router/hub's submap, it shows information only for the hub (NMS entity), and you cannot change any of its fields.

Figure 3-24: Router/Hub Describe Dialog Box



Table 3-34 describes the fields and command buttons in the Router/Hub Describe dialog box.


Table  3-34: Router/Hub Describe Dialog Box Fields and Command Buttons
Field or Command Button Description
Name Specifies the name of the hub for which the information is displayed. This name may contain up to 15 alphanumeric characters, including spaces, and is always displayed in uppercase.
Label Specifies an abbreviated name of up to eight characters that is displayed on the submap, computer, or component symbol in your map. The label is automatically taken from the Name field; it cannot be edited and is always displayed in uppercase letters.
Entities Lists the entities in the specified device. Double-clicking on a name opens its Interfaces dialog box. Entities are independent CPUs that contain SNMP agents to collect and relay information on the object. The entities listed are supported by the selected hub. The default is an NMS entity in slot zero (0).
Name Lists the names of the entities for this object. The names are listed in the format type_number. Type refers to the type of device, such as NMS or RTR. Numbers are sequential, starting with zero. Names are assigned automatically and cannot be altered. The entity with number zero (for example, NMS_0) performs all hub management functions.

Type

Specifies the two types of entities:

  • Network management modules (NMS)

  • Router (RTR)

Slot

Identifies the slot in the hub in which the entity is installed. Options are 0 and 1. Slot 0 is the lower slot andphysically contains the NMS module; this slot is assigned by default to the NMS entity. Slot 1 contains the Token Ring (LBM) or Ethernet (ECM) module; this slot is assigned by default to the RTR entity.
Configured Indicates whether the entity has been configured (triangle) or not configured (dash). This symbol changes only after you exit and reenter the Describe dialog box.
Notes Allows you to enter text. For example, you might want to record line speed, room location, or when preventive maintenance was last performed.
Add... Displays the Add New Entity dialog box, which allows you to add a new entity to the list of entities supported by the selected hub.
Update... Modifies entity information for the specified device. In the Entities box, select an entity, then click Update to change its type or slot while retaining all other parameters. Click OK to confirm your changes and return to the Describe dialog box.

Type Specifies the interface type of the selected entity: ET (Ethernet), PC (PCbus), SL (SLIP ), or TR (Token Ring),
Segment Specifies a ring number or segment name. This is an alias composed of letters and numbers for the ring or segment on which the interface (for example, the NMS module) is connected. You must use the same name in the Segment text box for all hubs whose NMS modules are on the same segment. When Ring Manager is running, it automatically inserts this parameter in an empty field.
Telephone Specifies an optional telephone number of the contact person for the specified hub. Remember to include all prefixes and area codes.
MAC Address Specifies the MAC address of the interface. For example, you can specify the address of the LAN adapter installed on the NMS interface module in the hub. If left blank, this field is filled in automatically. Whenever you assign a MAC address to a Token Ring device, select Sync. MAC Database under Ring Manager in the Control menu to update the database with the new address information.

TCP/IP Parameters

Presents a series of fields into which you can enter communications data for the selected interfaces. Check the boxes for each protocol supported by the interface: TCP/IP or SNMP. Then complete the following communications fields:

  • IP Address--Enter the IP address of the interface. This entry is mandatory.

  • Net Mask--Enter the net mask for the interface's address. The default net mask for the given IP class address is automatically inserted when the field is blank (for example, Class C default is 255.255.255.0).

  • Default Gateway--Enter the address of the interface's default gateway (optional).

Current Interfaces

Displays the interfaces currently supported by the selected entity.
Add Adds another interface to the list currently supported by the entity. A maximum of three interfaces is supported per entity.
Update Updates the interface selected in the list of Current Interfaces.
Remove Removes the selected interface from the entity and from the list of Current Interfaces.
Clear Retains the selected interface but erases its interface-specific information.

Miscellaneous Operations

This section discusses other operations of Cisco Hub/Ring Manager for Windows.

Using SNMP Manager

HP OpenView for Windows provides a special dialog box, called SNMP Manager, that you can use to get and set MIB variables in the SNMP agent.

To open the HP OpenView SNMP Query dialog box, perform the following steps:

Step 1 From your network map, click on a router/hub object.

Step 2 From the Control menu, click SNMP Manager.

Step 3 Click Select Query.

Step 4 From the Query list, select cmosip.ovq.

The cmosip.ovq file contains a query for an SNMP action. The HP OpenView SNMP Query dialog box appears with the relevant variables, as shown in Figure 3-26. After making any changes to the MIB variables, reset the agent through the control panel or the appropriate SNMP variable.


Figure 3-26: SNMP Manager Dialog Box



For more information on this dialog box, refer to the HP OpenView Windows User's Guide. For more information on these MIB variables, refer to the appendix "MIB Group and Trap Descriptions."

Identify Node

The Identify Node dialog box provides information on an occupied port of the router/hub. From the Identify Node dialog box, you can only view information; you cannot alter any of the text fields.

To open the Identify Node dialog box, perform the following steps:

Step 1 From your network map, select a router/hub.

Step 2 From the Control menu, select Control Panel. The graphical representation of the router/hub appears.

Another way to open the Control Panel is to click the right mouse button on the router/hub object and select Control Panel from the popup menu.


Step 3 Point to an occupied port (one showing a green light) on the router/hub, then click the left mouse button and select Identify.

The Identify Node dialog box appears, as shown in Figure 3-27.



Figure 3-27: Identify Node Dialog Box



You can also open the Identify Node dialog box by performing one of the following operations:

Table 3-36 describes the fields and command buttons in the Identify Node dialog box.


Table  3-36: Identify Node Dialog Box Fields and Command Buttons
Field or Command Button Description
Object Name Specifies the name of the device.
Object Type Specifies the type of device, such as router/hub.
MAC Address Specifies the MAC address of the node.
Node Type Specifies the type of node, such as Token Ring or Ethernet.
Connector Type Specifies the connector of the node, such as RJ-45.
