Managing Devices
In Cisco netManager, devices are virtual representations of resources (computers, servers, and so on) that are connected to your computer through a Local Area Network (LAN), a wireless network, or even over the Internet. Cisco netManager watches these devices through the network connection. When those network resources cannot be reached by Cisco netManager, the device is considered down and an action can be configured to fire.
You can add devices by importing device credentials using a seed file, or manually adding individual devices. For more information, see the following topics:
•
"Adding a New Device" section
• "Importing Devices from a File" section
IP Phone Discovery
Cisco netManager performs an auto-discovery on all IP phones every four hours to detect if SIP and SCCP IP Phone are associated with a managed Cisco Unified Communications Manager or Cisco Unified Communications Manager Express. Cisco netManager also verifies registration status of all detected IP phones with Cisco Unified Communications Manager or Cisco Unified Communications Manager Express.
Note The ability to view and monitor IP communication devices depends upon the type of licensing you have.
Device Services
Cisco netManager associates active monitors with devices on your network. Active monitors query the network services installed on a device and then wait for a response. These monitors query the services running on a network resource, checking to make sure that the FTP server, web server, email server, etc., are up and responding. Active monitors include DNS, SNMP, Telnet, Ping, TCPIP, and NT Service. If a response is either not received or is not what is expected, the service is considered down. If the query is returned as expected, the service is considered up. If any one service on a device is down, then the device as a whole is considered down.
For a more information about service monitors, see Chapter 8, "Using Active Monitors."
About the Devices Tab
This view provides an overview of all the devices in your network.
With a look and feel similar to Windows Explorer, the My Network tree helps you keep your complex network organized and performing properly. Devices are organized by device group, and appear in the list in alphabetical order based on the name of the folder or the display name of the device. For more information on the type of information displayed, see "Device List" section.
During discovery, device groups are created for each subnetwork that is found on the network that was scanned. At the top level of the My Network tree, all devices of the entire scan are contained in the All devices folder. The second folder is the All routers folder and contains all devices that can function as a router. The folders below All devices and All routers are specific device groups that are categorized by associated device rules. For more information on these groups, see "Understanding Device Groups" section.
Device List
Each device on the list provides information about its device type, capabilities, and status. The capabilities column indicates the different roles that the device is capable of. For example, if a device has the capability of being a router and an H323 gateway, the column would list both router and H323 Gateway. The Status column describes any faults or events on the device. For a description of each event listed in the Status column, see List of Events, page 14-17.
Note If you right-click a device in the device list to acknowledges its events, all the events for that device are marked as acknowledged. For more information, see Using Acknowledgements.
Figure 5-1 shows an example of a device list.
Figure 5-1 Device List
Context-Sensitive Menu
A context-sensitive menu is available on the web interface of the Devices tab. The context-sensitive menu comes up when you right-click a device or device group. This menu contains a list of tools that can be used on the device or device group. The type of tools that are available depends on the type of device you have selected. For more information on the standard network tools available, see Launching Network Tools, page 17-12.
Figure 5-2 shows an example of the Context-sensitive Menu.

• New Group. Adds a new device group to your list of monitored devices.
• New User Defined Group. Adds a new user-defined group to your list of monitored devices.
Device States and Icons
Each folder in the My Network tree has a device state indicator on the folder icon. This indicator shows the worst state across all of the devices contained in that folder.
The following icons appear in the device list when viewing the contents of a device group.
Icon
|
Description
|
|
(Green) All monitors on the device are considered up.
|
|
(Red) Device is considered down, because one or more monitors are down. The green square shows that at least one monitor is responding.
|
|
Device entry appears in another device group. At least one monitor on the device is unresponsive, but at least one is considered up.
|
|
(Orange) Device is currently in maintenance mode.
|
|
Device group contains at least one device that is considered down.
|
|
Device group is empty, or devices have not been polled due to a dependency on another device.
|
|
A bold device name shows that the device has undergone a state change, and that state change has not been acknowledged. For more information about acknowledgements.

Understanding Device Groups
A group consists of objects, where objects refer to devices and groups. Each group has a set of properties (such as a name, description, permission, and so on), but what define a group are its associated rules. Rules determine the membership of a group, which may change whenever the rule is evaluated.
The following types of groups are supported:
•System-Defined groups—The default grouping of devices that cannot be deleted or edited. For a description of each system-defined group, see the Working with System-Defined Groups.
•Dynamic groups—A dynamic group that you can create by defining an sql query. Dynamic groups act as SQL queries that run on the Cisco netManager database, and can display real-time data if viewed through a report that is set to automatically refresh. For more information on dynamic groups, see the "Using Dynamic Groups" section
•User-Defined groups—A dynamic group where the user can group devices using one of the following criteria: location, description, contact or IP address. To create a user-defined group, see "Creating a User-Defined Group" section.
Note The supported format for an IP address is a set of four octets (*.*.*.*). An asterisk (*) denotes the octet range of 1-255. You can filter IP addresses using the octets in a sequential order. For example, if you filter devices with IP addresses containing 10.76.91, your results may include 10.76.91.151 or 172.10.76.91. You cannot use an IP range or wildcards, for example 10.*.91.
•Static groups—Groups that you edit or create to reflect the way you manage the network. You can edit or create device groups and determine whether they can be viewed by other users. To create a static group, see "Creating a Device Group" section.
Working with System-Defined Groups
The system-defined groups are visible to all users, and are the default groups that are administered by Cisco netManager. If a device has multiple capabilities, the device will be listed under all appropriate groups. For example, if a device can function as a router, H323 gateway and a MGCP gateway, it will be listed in all those groups.
Note System-defined groups cannot be modified or deleted.
Note The ability to view and monitor IP communication devices depends upon the type of licensing you have.
The following system-defined groups come preconfigured:
•Routers
•Switches
•Hosts
•Servers
•Cisco Media Server
•Cisco Unified Communications Manager
•Cisco Unified Communications Cluster. Lists subgroups of the Cisco Unified Communications Manager cluster group and contains all of the devices associated with the corresponding instance of the Cisco Unified Communications Manager cluster.
•Cisco Unity
•Cisco Unity Connection
•Cisco Unity Express
•Cisco Unified Communications Manager Express
•Cisco Unified Conferencing Express
•Cisco Unified Contact Center Express
•Cisco Unified Communications Manager - Business Edition
•H323 Gateways
•MGCP Gateways
•SRST Devices
•Wireless LAN Controllers
•Wireless Access Points
•Security Devices
Creating a Device Group
To create a static device group:
Step 1 Do one of the following:
•From the My Network tree in the Device tab, right-click on a folder, and select New Group....
•Click the New Group icon located on the top right of the Device tab.
Step 2 Enter the name of the new group you are creating.
Step 3 Enter the description for the new group.
Step 4 Click OK.
Modifying Group Properties
Step 1 Do one of the following:
•From the My Network tree in the Device tab, right-click on a folder, and select New Group....
•Click the New Group icon located on the top right of the Device tab.
Step 2 Modify the name of the group.
Step 3 Modify description of the group.
Step 4 If you are modifying a dynamic group, select appropriate user access privileges for that group.
Step 5 Click OK.
Creating a User-Defined Group
Step 1 From the My Network tree in the Device tab, right-click User Defined Group folder, and select New User Defined Group....
Step 2 Enter the name of the new group you are creating.
Step 3 Enter a description for the new group.
Step 4 Select the attribute that will be used to filter devices for the group; for example, location.
Step 5 Enter the attribute value; for example, California.
Step 6 Click OK.
Modifying Group Access Rights for a User
Step 1 From the My Network tree in the Device tab, right-click User Defined Group folder, and select Properties.
Step 2 Check the appropriate Read/Write access rights.
Step 3 Click OK.
Renaming a Device Group
To rename a device group, right-click on the group in the My Network tree, click Properties, then change the name in the Group Name box.
Using Dynamic Groups
This feature provides the ability to create device groups based on whatever criteria users choose, without having to create device shortcuts. Dynamic groups can be created for specific device types, device attributes, active monitors, or anything else that is stored for individual devices in the database. Dynamic groups act as SQL queries that run on the Cisco netManager database, and can display real-time data if viewed through a report that is set to automatically refresh.
Cisco netManager is pre-configured with dynamic group examples. You can view these examples from the Dynamic Group Examples folder, under the My Network tree in the Devices tab.
All of the Dynamic Group Examples are active, so if you have devices that meet the criteria, you will see the device displayed within the group. In the web interface, the dynamic group display is refreshed every 2 minutes. A group is also refreshed when you select it.
To view or edit the criteria for a dynamic group, right-click the group name, then select properties.
Note Dynamic groups on the web interface do not follow group access rights. Anyone with the ability to view the device group that a dynamic group is in can access that dynamic group. However, only devices that the user has the permission to view appear in the group.
To configure dynamic groups:
Step 1 From the My Network tree in the Device tab, right-click a folder, then select New Dynamic Group. The Dynamic Group dialog box opens.
Step 2 Enter a display name for the group, enter the group description, and enter an SQL query in the Filter box that identifies the devices you want to appear in that group.
Step 3 Click OK to add the group to the device list. SQL validation occurs as soon as you click OK. If the filter fails, an error message appears.
In addition to the pre-configured dynamic groups, we have provided several sample filters for you to create some dynamic groups.
Tip If you do not know how to formulate SQL queries, you can cut and paste filter entries from existing dynamic groups, then edit them to read data from other tables.
Dynamic Group Examples
The following table lists several dynamic group filters that you can use to create dynamic groups for your devices. To use these examples, select the text of the filter, and then copy and paste the text into the Filter box of the Dynamic Group dialog box.
Note You may have to remove the copyright information from the cut and paste if it appears when you copy from this help file.

This group shows all device groups (except itself) in a rotating order. For example, if the State Change Timeline report is using this Rotating Group, every minute, when the report auto-refreshes (or when the user presses F5), this Rotating Group looks at a different Dynamic Group. So, it might look at Dynamic Group A first, then B, then C, etc., and then start back at the beginning. The effect is like a security guard's monitor: The scene changes from the front door, to the back door, to the loading dock, to the hallway, back to the front door, etc.

Creating Access Rights for a Device Group
An important part of creating a device group is configuring the appropriate access rights for that group. Group access rights ensure that only those users with specific rights are allowed to view and modify a device group.
Step 1 From My Network tree in the Device tab, right-click on a group, and select Properties.
Step 2 From the Group Properties dialog box, you can add and edit the access rights for the selected group. For more information on the types of tasks associated with each access right, see User Access Rights for a Device Group.
Note You must enable group access rights for a user account before a user can add or edit access rights for a device group. To do this, the Cisco netManager administrator will have to enable group access rights for a user in the Manage Users dialog box (Configure > Manage Users).
User Access Rights for a Device Group
Device Group Access Rights lets the administrator determine which device groups certain web users are allowed to view or edit.
The following is a list of operations and the group access rights that must be assigned for the user to perform those operations:
• List, Map, and Group reports in the Group Views menu require Group Read access.
• Create Group and Group Properties in the Group Operations menu require Group Read Write access.
• Copy Group requires Group Read in the source group, and Group Read Write in the destination group. (Permissions to groups and subgroups are copied, not inherited from the new parent).
• Move Group requires Group Read Write in both the source and the destination groups. (Permissions of the group and subgroups remain the same.)
• Delete Group requires Group Read Write, Device Read Write recursively. (Device Read Write may not be required if the group is empty).
• Create Device requires Group Read Write and Device Read Write. If the device already exists in other groups, you must also have Group Read Write and Device Read Write in one or more of those groups.
• Copy Device requires Group Read in the source group and Group Read Write in the destination group. The level of device permissions must be the same in both groups. Downgrade from Device Read Write to Device Read is also permitted.
• Move Device requires Group Read Write in both the source and the destination groups. The level of device permissions must be the same in both groups. Downgrade from Device Read Write to Device Read is also permitted.
• Viewing Device Properties and Device Reports requires Device Read.
• Modifying Device Properties, Bulk Field Change, and Acknowledgement require Device Read Write.
Understanding Device Properties
You can modify individual device properties by right-clicking a device in the Device List, then selecting Properties.
The Device Summary page displays basic information about a device, including:
•Display Name—Displays the identifying name for the current device. This name is populated during discovery, but can be changed by the user at any time in the Device Properties - General page. Changing the name will not change how the device is polled; it affects only how it is displayed in Cisco netManager.
•Device Type—Displays the type of device (printer, workstation or router, for example). The device type can be changed on the Device Properties - General page.
•Host name—Displays the DNS name of the device.
•Address—Displays the IP address of the device.
The icon associated with the device, over a colored shape that indicates the worst state of any of the active monitors on the device, is displayed to the left of Device Name. The icon can be changed on the Device Properties - General page.
Additional attributes associated with the device (Location, Contact and Description as well as any custom attributes) are displayed below the device icon. Attributes can be added, modified or removed from the Device Properties - Attributes page.
Notes display any associate with the device. Notes are managed on the Device Properties - Notes page.
The following topics give an overview of the device properties available to use and modify.
• General Device Properties
• Device Property Performance Monitors
• Active Monitor Device Properties
• Passive Monitor Device Properties
• Device Property Actions
• Device Property Polling
• Device Property Credentials
• Device Property Notes
• Device Property Custom Links
• Device Property Attributes
General Device Properties
The General section of the Device Properties dialog box provides, and lets you modify, basic information for the selected device.
• Display name—An identifying name for the current device. This name is populated during discovery, but can be changed by the user at any time. Changing the name will not change how the device is polled, only how it is displayed in Cisco netManager.
• Polling type—Select the type of polling you want Cisco netManager to use for this device.
– ICMP (TCP/UDP)
– IPX
– NetBIOS
Note If NetBIOS is selected, the Host Name box must contain a valid NetBIOS name. If IPX is selected, the Address box must contain a valid IPX address. If NetBIOS or IPX is selected, you cannot monitor TCP/IP services on this device.
• Poll using—Select if you want Cisco netManager to use the IP address or the hostname (DNS) of the device for polling.
• Host name (DNS)—This should be the official network name of the device if the polling method is ICMP. The network name must be a name that can be resolved to an IP address. If the polling method is NetBIOS or IPX, this must be the NetBIOS or IPX name.
• Address—Enter an IP or IPX address.
• Additional Network Interfaces—Click this button to configure an additional Network Interface for the current device.
• Device Type—Select the appropriate device type from the pull-down menu. The icon displayed will represent the device in all views.
Device Property Performance Monitors
The performance monitors section of the Device Properties dialog box lets you configure and manage performance monitors for the selected device. To get to this dialog box, right-click on a device from the device list, and select Properties > Performance Monitor. For more information, see Chapter 10, "Using Performance Monitors."
Note For some performance monitors, the SNMP credential on the device must be configured. For WMI performance monitors, the NT credential is required.Enable/Disable Performance Monitors— Select options in this list to enable monitors.
If you select a specific performance monitor without configuring the monitor manually, the default collection type is automatically selected. The collection type refers to the item on the current device that is being monitored (this does not pertain to the custom WMI and SNMP monitors that may appear). For Cisco devices all performance monitors, except Interface Utilization and Ping Latency and Availability, will be enabled by default.
Performance monitors will be associated with the device based on its capabilities:
Note The ability to view and monitor IP communication devices depends upon the type of licensing you have.

The top list displays active monitors that have been defined in the Active Monitor Library with the Use in Discovery option selected. The bottom list displays all performance monitors defined in the Performance Monitor Library. For more information about performance monitors, see Chapter 9, "Using Passive Monitors."
• Use comprehensive discovery—By default, Cisco netManager sends a ping command to each viable IP address in the range configured in the first section of this wizard. If the device responds, Cisco netManager then scans for the monitors listed on this dialog box. If no device responds, discovery moves on to the next IP address. Select this option to have device discovery scan each IP address for all of the selected monitors without first sending the ping command to the device. Discovery will take longer if this option is selected.
Note If you want a ping monitor created for the devices found in discovery, you must select Ping as an 'active monitor to scan' even if you have cleared the Use comprehensive discovery option.
During discovery, interface monitors are added after the scan, only if a device has multiple physical interfaces. If a device only has 1 interface, then no interface monitors are added, even if the interface monitor is selected to be scanned. Loopback interface doesn't count.
• Resolve host names. Select this option to have Cisco netManager attempt to populate the list of discovered devices with host names, instead of IP addresses. Clear this option to have the list show only IP addresses of discovered devices.
• Identify device via SNMP. Select this option to have Cisco netManager read the SNMP information on the device.
• SNMP read communities. Enter one or more community strings, separated by commas, that the device will respond to. If the read community string is incorrect, or none is provided, Cisco netManager determines device type based on the monitors discovered during the scan.
Note This option is only available when adding a single device.
• Windows credentials. Select a Windows credential to use when attempting to discover devices where you have to provide a Windows username or password when connecting. Credentials are configured in the Credentials Library. When a device is discovered using a credential, that credential is then associated to that device. You can change this on Device Properties > Credentials. If you select All, discovery uses all configured credentials in the Credentials Library. The credential that is successful is then associated with the device.

Rediscovering Devices
This task rediscovers all the devices in the network. You would want to perform this task if device credentials, capabilities, etc., are changed. During rediscovery, if device capabilities have changed, associated monitors and data inventory are updated. If a device is unreachable, the device status will be updated accordingly. This can be a time-consuming task that will allow you navigate the web interface, but not perform any operations.
To rediscover devices:
Step 1 From the Go menu, select Device > Rediscover Devices...
Step 2 Click OK.
Note If you cannot rediscover a device's new capabilities because you have reached the device count limit of your license, an appropriate error message will appear.
Suspending and Resuming Single Device Polling
This task permanently suspends or resumes polling on a specific device.
Step 1 From the device list, right-click a device. From the context menu, click Device Management > Suspend or Device Management > Resume.
Step 2 Click OK.
Device Types
In the left-hand pane of the Cisco netManager console interface, the Device Types (icons representing the types of devices you may have on your network) appear.
Click the tab at the bottom of the pane to switch from Device Types (Basic) to Device Types (Advanced).
You can select a device type in the Device Properties General dialog box on the console or web interface. When you change a device type on an existing device, you are only changing the icon that represents the device; you are not adding additional information and settings to the device. All other changes will have to be done manually. For more information about selecting a specific device types for existing devices, see "Changing Device Types" section.
Configuring Device Types
If you want Device Discovery to use a special icon when it finds this device, make sure you have run the MIB extractor.
Step 1 From the console, click Configure > Device Types > New.
Step 2 Enter a Device Type Name for the new device.
Step 3 In the Icon filename box, browse to a graphic file to represent the device.
Step 4 In the Overlay text box, you can enter a word or two which will overlay the device icon to help differentiate this device. For example, HP Laser will help differentiate this device from other printers which use the same icon.
Step 5 Select the device Polling type.
Step 6 (Optional) In the SNMP Object ID text box, enter an SNMP identifier (or use the browse button (...) to find one) that corresponds to a vendor device type; this is usually found in the private > enterprises section of the MIB tree, under the vendor name.
Device discovery finds and maps devices using the SNMP identifiers to locate the specified devices. To scan for devices, you must also enter the proper community name.
You can use multiple identifiers. For example, suppose a manufacturer named Acme makes three devices: the Acme 4500, the Acme 4501, and the Acme 4502. You could define one device type to represent any Acme device in the 4500 series; in the SNMP Object box, you would enter the three SNMP identifiers for the Acme 4500, 4501, and 4502. The Scan tool uses the icon for any of the three devices.
You need to separate multiple SNMP object identifiers by using semicolons. The last number in the identifier can be an asterisk, can be a range using hyphens, or can contain multiples separated by commas. For example:
1.3.6.1.4.1.311.1.1.3.1.3
1.3.6.1.4.1.311.1.1.3.1.3;1.3.6.1.4.1.311.1.1.3.1.4
1.3.6.1.4.1.311.1.1.3.1.3,4
1.3.6.1.4.1.311.1.1.3.1.1,3-4
1.3.6.1.4.1.311.1.1.3.1.*
Step 7 Click Next to save the new device type, and access the Active Monitor dialog for device types.
Step 8 Click Add to add an active monitor for the device type.
Step 9 Click Next to access the Passive Monitor dialog for device types.
Step 10 Click Add to add a passive monitor for the device type.
Step 11 Click Next to access the Context Menu dialog for device types.
Step 12 Click Add to add a context menu for the device type.
Step 13 Click Next to access the Action policy dialog for device types.
Step 14 Associate an action policy, or click the browse button to create or edit an action policy.
Step 15 Click Finish to save the new device type.
Changing Device Types
Device Types act like templates for new devices, containing device properties (such as active and passive monitors, menu items, etc.) and represented by different icons in Device Properties.
When you change a device type on an existing device, you are only changing the icon that represents the device, and not adding additional information and settings to the device. If you rediscover the device, the icon will change back to the original device type. All other changes will have to be done manually.
To change a device type icon on an existing device:
Step 1 In Device view, right-click on a device. In the context menu, click Properties > General.
Step 2 In the Device type list, select a new device type.
Step 3 Click OK to save changes.
Editing Multiple Devices with Bulk Field Change
The Bulk Field Change feature gives you the ability to make changes to multiple devices and device groups. You must have administrative privileges to the devices or device groups that you want to make changes to.
To edit multiple devices:
Step 1 Select the devices or device groups you want to change, then right-click and select Bulk Field Change. The Bulk Field Change context menu opens.
Note When you select a device group, every device in the group, and any subgroup of the group, will reflect the bulk field change.
Step 2 Select the field you want to change. The following items can be modified through Bulk Field Change:
• Credentials
• Polling Interval
• Maintenance Mode
• Maintenance Schedule (web interface only)
• Device Type
• Action Policy
• Up Dependency
• Down Dependency
• Notes
• Attribute
• Performance Monitors
• Active Monitor
• Active Monitor Properties
• Passive Monitor (web interface only)
• Passive Monitor Properties (web interface only)
Step 3 Enter the configuration information that you want to set.
Step 4 Click OK to save changes.
Using Acknowledgements
When a device state changes, regardless of any action that has been placed on the device, Cisco netManager uses the Acknowledgement feature to make you aware that the state change occurred. The device name appears in bold in the Device List.
After the device is in Acknowledgement mode, it will remain so until you actively acknowledge it.
Note Acknowledging a device state change does not keep that device from firing actions. To stop a device from firing actions, you must put the device into Maintenance mode.
To acknowledge a state change, select the device or devices you want to acknowledge, right-click, then click Acknowledge Events. For a list of events, see List of Events, page 14-17.
Credentials Overview
The Credentials system stores login or community string information for Windows (WMI Active Monitors and WMI Performance Monitors) and SNMP devices in the Cisco netManager database. The system supports SNMP v 1, 2, and 3.
Credentials are configured in the Credentials Library (found on the web interface menu at Go > Configure > Credentials Library) and used in several places throughout the application. They can be associated to devices in Device Properties > Credentials or through the Credentials Bulk Field Change option.
A device needs SNMP credentials applied to it before SNMP-based Active Monitors will work. Similarly, NT Service Checks must have Windows credentials applied.
