    Monitoring the Policy Configuration of IPv6 Interfaces

    Purpose

    Display detailed or summary information, including policy and classifier information, for a particular IPv6 interface or for all interfaces. The default for the show ipv6 interface command is all interface types and all interfaces. The brief or detail keywords with the show ipv6 interface command displays different levels of information.

    Action

    To display information about IPv6 policy lists:

    Note: If you enable scheduler profile–based computation of service session accounting by using the service-accounting- statistics scheduler-based command, the forwarded packets and bytes fields, and the dropped packets and bytes fields are displayed in the rate-limit-profile section under the IPv6 policy output heading for policies with hierarchical parent groups. The committed, conformed, exceeded, saturated, and unconditional packets and bytes fields are not displayed in the rate-limit- profile section in the output of the command for policies with hierarchical parent groups. These fields are displayed instead of the forwarded packets and bytes fields, and the dropped packets and bytes fields only if you disable scheduler profile-based computation of service session accounting.

    Note: When the classifier-specific statistics accounting feature is enabled for a classifier group, the sum of 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 IPv6 policy input and output sections always display the number of bytes as a sum of 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.
