Message
DHCPSNP/4/REPLYLOG: The number of the discarded DHCP reply packets on the untrusted interface exceeded the threshold. (IfIndex=[IfIndex], VlanIndex=[VlanIndex], VsiIndex=[VsiIndex], Interface=[IfName], VlanID=[VlanId], DiscardedNumber=[DiscardPktAccount])
Description
The number of DHCP reply packets discarded on an untrusted interface exceeded the configured threshold.
Parameters
| Parameter Name | Parameter Meaning |
|---|---|
IfIndex |
Indicates the interface index. |
VlanIndex |
Indicates the VLAN index. |
VsiIndex |
Indicates the VSI index. |
Interface |
Indicates the interface name. |
VlanId |
Indicates the VLAN ID. |
DiscardedNumber |
Indicates the number of discarded packets. |
Possible Causes
The number of DHCP reply packets discarded on an untrusted interface exceeded the configured threshold.
Procedure
- Run the display dhcp snooping [ interface interface-type interface-number | vlan vlan-id ] 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.
