    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.

    Note: When the classifier-specific statistics accounting feature is enabled for a classifier group, the sum of IPv4 or IPv6 and user payload header bytes excluding control overhead header bytes is sent to AAA for service accounting. The bytes fields under the classifier-group field in IP policy input and output sections always display the number of bytes as a sum of IPv4 or IPv6 header, user payload, and control overheads without depending on the status of the classifier-specific statistics accounting feature. For more information about the classifier-specific statistics accounting feature, see Classifier-Specific Statistics Accounting for Classifier Groups Overview.

    Note: When a parity error is detected for policy accounting statistics and the router is enabled to perform actions after parity error detection, an error message is displayed for those subscriber policies instead of the corrupted statistics details. For more information about the parity error check mechanism and system operations on detecting corruption, see Detection of Corruption in the Statistics FPGA and System Operations on Detecting Corruption.
