Monitoring Interfaces and Policy Lists

Purpose

Display information about an interface and its policy lists. The delta keyword displays baselined statistics and the brief keyword displays the operational status of all configured interfaces

Action

To display information about interfaces and policy lists:

Note: For tunnel interfaces, the packets field under the IP policy output section in the output of the show ip interfaces command displays the number of fragments or packets sent out from the tunnel interface for which an output policy is attached, depending on whether you enabled preservation of output policy statistics using the enable-frag-stats command. Although this field displays the unit of measure as packets, it denotes the number of fragments if statistics generation for output policies based on fragments is enabled. Otherwise, this field indicates the number of output policed packets on the tunnel interface.
