DHCP Snooping Statistics Fields
| Field | Description |
|---|---|
| Interface | The interface associated with the rest of the data in the row. |
| MAC Verify Failures | The number of DHCP messages that were dropped because the source MAC address and client hardware address did not match. MAC address verification is performed only if it is globally enabled. |
| Client Ifc Mismatch | The number of packets that were dropped by DHCP snooping because the interface and VLAN on which the packet was received does not match the client's interface and VLAN information stored in the binding database. |
| DHCP Server Msgs Received | The number of DHCP server messages (DHCPOFFER, DHCPACK, DHCPNAK, DHCPRELEASEQUERY) that have been dropped on an untrusted port. |
| Clear Counters (Button) | To reset the statistics to zero for one or more interfaces, select each interface with the data to reset and click Clear Counters. You must confirm the action before the entry is deleted. |
