(Optional) Configuring Alarm Thresholds for the Percentage of ND Snooping Dynamic Binding Entries

(Optional) Configuring Alarm Thresholds for the Percentage of ND Snooping Dynamic Binding Entries

Context

After setting the maximum number of ND snooping dynamic binding entries on an interface, you can set the alarm thresholds for the percentage of ND snooping dynamic binding entries.

When the percentage of learned ND snooping dynamic binding entries against the maximum number of ND snooping dynamic entries allowed by the device reaches or exceeds the upper alarm threshold, the device generates an alarm. When the percentage of learned ND snooping dynamic binding entries against the maximum number of ND snooping dynamic entries allowed by the device reaches or falls below the lower alarm threshold later, the device generates a clear alarm. The alarm information helps network administrators monitor the status of ND snooping binding table in real time.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run nd snooping user-alarm percentage percent-lower-value percent-upper-value

    The alarm thresholds for the percentage of ND snooping dynamic binding entries are configured.

    By default, the lower alarm threshold for the percentage of ND snooping dynamic binding entries is 50, and the upper alarm threshold for the percentage of ND snooping dynamic binding entries is 100.
