Chapter 59 Configuring Router Interfaces

Basic Interface Settings on Cisco IOS Routers

Note Frame relay must be configured on the parent interface.

Note IETF Frame Relay encapsulation provides interoperability between a Cisco IOS router and

equipment from other vendors. To configure Cisco Frame Relay encapsulation, use CLI

commands or FlexConfigs.

Step 11 (Optional) Enter a description of up to 1024 characters for the interface.

Step 12 Click OK to save the interface/subinterface definition and close the dialog box. The new interface is

displayed on the Router Interfaces page. Subinterfaces are displayed beneath the parent interface.

Deleting a Cisco IOS Router Interface

Although you can delete the definition of a virtual interface at any time, use this option with great care.

If the interface is included in any policy definitions that exist for this router, deleting the interface causes

these policy definitions to fail when they are deployed to the device.

Note Deleting the basic interface definition does not delete any advanced settings that are configured under

Interface > Settings > Advanced Settings. You must delete these advanced settings separately. If you

fail to do so, deployment fails.

Note Deleting the definition of a physical interface from the Router Interfaces page does not remove the

interface from the device. If you perform this operation by mistake, you can perform rediscovery to

restore the definition to Security Manager. For more information, see Discovering Policies on Devices

Already in Security Manager, page 5-15.
