Usage Guidelines

After you run the dhcp snooping max-user-number command to set the maximum number of DHCP snooping binding entries on an interface, you can run the dhcp snooping user-alarm percentage command to set the alarm thresholds for the percentage of DHCP snooping binding entries.

When the percentage of learned DHCP snooping binding entries against the maximum number of DHCP snooping entries allowed by the device reaches or exceeds the upper alarm threshold, the device generates an alarm. When the percentage of learned DHCP snooping binding entries against the maximum number of DHCP snooping entries allowed by the device reaches or falls below the lower alarm threshold later, the device generates a clear alarm.

Example

# Set the lower alarm threshold for the DHCP user count percentage to 30 and the upper alarm threshold to 80.
