Impact on the System

This alarm has no adverse impact on the system, because trusted interfaces discard all DHCP reply packets from illegitimate DHCP servers.

Possible Causes

The number of DHCP reply packets discarded on an untrusted interface exceeded the configured threshold.

Procedure

1. Run the display dhcp snooping { interface interface-type interface-number | vlan vlan-id [ interface interface-type interface-number ] } command to check whether the interface is configured as a trusted interface.

1. If the interface is configured as a trusted interface, this log message is informational only, and no action is required.

2. Collect log information and configuration information, and then contact technical support personnel.
