Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

PrefixCount

Indicates the number of IPv6 public route prefixes in the routing table.

Threshold

Indicates the threshold of the number of IPv6 public route prefixes.

Impact on the System

The number of IPv6 public route prefixes exceeded the alarm threshold, and services may be affected if the number of IPv6 public route prefixes keeps increasing.

Possible Causes

Cause 1:

A large number of IPv6 dynamic protocol routes (BGP or IGP routes for example), static routes, or direct routes were added to the routing table.

Cause 2:

The threshold of the number of IPv6 public route prefixes was decreased.

Procedure

  1. Run the display current-configuration command to check whether the threshold value specified in the ipv6 prefix-limit command is too small.

    • If the threshold value is too small, go to 2.
    • If the threshold value is in a proper range, go to 3.

  2. Rerun the ipv6 prefix-limit number alert-percent command to increase number and alert-percent.
  3. Run the display ipv6 routing-table statistics command to check the number of IPv6 public route prefixes and the number of routes of each protocol that are added to the routing table.

    Check whether services need these routes or whether the routes are added to the routing table due to incorrect configurations.
    • If the routes are added to the routing table due to incorrect configurations, go to 4.

    • If services need these routes, replace the license or contact technical support personnel for specification expansion.

  4. Adjust the configurations to delete unneeded routes, and check whether the RM_1.3.6.1.4.1.2011.5.25.145.19.2.4 hwPublicIpv6PrefixThresholdExceedClear alarm is generated.

  5. Collect alarm information and configuration information, and then contact technical support personnel.
  6. End.
