Parameters

Parameter Name	Parameter Meaning
BdIndex	Indicates the bridge domain name.
DiscardPktAccount	Indicates the number of discarded packets.

Possible Causes

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.

If the interface is configured as a trusted interface, this log message is informational only, and no action is required.
If the interface is configured as an untrusted interface, check whether the configured threshold for the number of DHCP reply packets discarded on the interface is proper and whether the device is attacked, so that you can determine whether to adjust the alarm threshold.
