Interface Configuration

Interfaces on port adapters can support multiple technologies. Configuration windows are technology-specific. For example, a POS interface supports three configurable technologies:

Generic
POS
IP

Therefore, to view or modify the configuration of a POS interface, you might need to view three windows:

Generic Interface Configuration
POS Interface Configuration
IP Interface Configuration

This applies to viewing or modifying all different types of interfaces. The following table lists the technology-specific configuration windows that apply to each interface type.

Table 7-1 Interfaces and Configuration Windows

Interface	Technology-Specific Configuration Windows
POS	Generic POS IP SONET
ATM	Generic ATM IP SONET
Ethernet	Generic Ethernet IP

Generic Interface Configuration

This section covers the following topics:

Viewing the Generic Interface Configuration Window

To view the Interface Configuration window:

Right-click any selected port adapter or interface, then choose CERM Management > Physical > Interface > Generic > Configuration. The Interface Configuration window appears (Figure 7-1).

Figure 7-1 Interface Configuration Window (Configuration Tab)

Configuring and Commissioning an Interface

To configure and commission an interface:

Tip You might want to commission an interface if you have interfaces that are not yet connected or live. For example, when you commission a chassis, subchassis discovery is automatically initiated.

Step 1 From the Interface Configuration window, choose the chassis, module, and interface from the lists displayed on the left side of the window.

Note The status of the selected module appears at the bottom left corner of the window.

Step 2 To commission or decommission an interface:

To commission the selected interface, click Commission. Commissioning the interface allows Cisco 7200/7400 Series Manager to determine which state to move the interface into (typically normal).
To decommission the selected interface, click Decommission. Decommissioning the interface changes its status to decommissioned.

Step 3 You can change any available information in the Configurable Parameters area. Information that is not available for selection on a particular item is grayed out.

Step 4 Click the Save icon to save the changes.

Generic Interface Configuration Window—Detailed Description

The Interface Configuration window (see Figure 7-1 ) contains a single tab: Configuration.

Configuration Tab

The Configuration tab contains two areas: Configurable Parameters and Actions.

Configurable Parameters

The Configurable Parameters area contains the following fields:

Alias—Name for the interface, as specified by the network manager.
Administration Status—Allows you to enable, disable, or reset the module.
Link Up/Down Trap Enable—Allows you to choose whether link up/down traps should be generated for this interface.
Supplementary Information—Additional information.

Actions

The following are available from the Actions area:

Commission—Click to commission the selected interface.
Decommission—Click to decommission the selected interface.

IP Configuration

The IP Configuration window allows you to configure generic IP fields (such as IP address, interface state, and so on).

The IP Configuration section covers the following topics:

Viewing the IP Configuration Window

To view the IP Configuration window:

Step 1 Right-click a selected IP port adapter or IP interface, then choose CERM Management > Physical > Interface > IP > Configuration. The IP Configuration window appears, with the Generic Parameters tab displayed (Figure 7-2).

Figure 7-2 IP Configuration Window (Generic Parameters Tab)

Step 2 Choose a chassis, module, and IP interface from the lists displayed on the left side of the window.

Step 3 You can now configure any of the fields in the tabs. For detailed information on these fields, see the "IP Configuration WindowDetailed Description" section.

Step 4 Click the Save button when you are finished.

IP Configuration Window—Detailed Description

The IP Configuration window (see Figure 7-2) contains two tabs: Generic Parameters and Hot Standby Router Protocol (HSRP) Parameters.

Generic Parameters Tab

HSRP Parameters Tab

The HSRP Parameters tab is shown in Figure 7-3.

Note Cisco 7200/7400 Series Manager can support the configuration of only one HSRP group.

Standby Priority—Enable or disable the priority for the HSRP interface. Possible values are between 0 and 255.

Enabled: When the current interface fails, it automatically switches to the standby interface.
Disabled: When the current interface fails, it does not switch to a standby interface.

Priority—Value that prioritizes a potential hot standby router. The range is 1 to 255; the default is 100.
Standby Authentication—Enable or disable the standby authentication string.

Enabled: Checks for an authentication string set and allows you to configure the interface if the string set is found.
Disabled: Does not check for an authentication string.

Authentication String—Serves as a check to avoid any damage to the interface. It can be up to eight characters in length. The default string is "cisco".
Standby Hello Time—Measured in seconds; can be an integer from 1 to 255. The default is 3 seconds.

Configuration Tab

The Configuration tab (see Figure 7-7) contains a single area: General.

General

The General area contains the following fields:

Loopback—The following options are available:

Internal: No cable is needed to connect the input and output ports. The data is looped back within the device itself. Applicable only for Gigabit and Fast Ethernet interfaces.
External: Input and output ports are physically connected by a cable to simulate a loopback. When data is transmitted, it travels through the output port and enters the device through the input port. Applicable only for Gigabit and Fast Ethernet interfaces.
Enabled: Packets are transmitted back to the source to test the interface functionality and ensure that packets transmitted through the interface reach the intended destination without data loss. Applicable only for Ethernet interfaces.

Caution When the loopback for the Ethernet interface is enabled, the Ethernet communication link to the Cisco 7200/7400 Series Manager is lost.

Disabled: Restricts receipt of connection status (Success or Failure) messages. Applicable for GRP Ethernet, Gigabit, and Fast Ethernet interfaces.
Keepalive Period: Displays the set keepalive time period. The system sends packets to verify if the interface or the network is up for routing packets. The default is 10 seconds.

MAC Address—Specify the MAC address of the interface. Each interface is identified by a unique MAC address.
