Filtering CDP information

In some environments it is desirable to be able to configure a switch to handle CDP packets by filtering out the

MAC address learns from untagged VLAN traffic from IP phones. This means that normal protocol processing

occurs for the packets, but the addresses associated with these packets is not learned or reported by the software

address management components. This enhancement also filters out the MAC address learns from LLDP and

802.1x EAPOL packets on untagged VLANs.

The feature is configured per-port.

Enter this command to configure the switch not to learn CDP, LLDP, or EAPOL traffic for a set of interfaces.

[no] ignore-untagged-mac <port-list>

Prevents MAC addresses from being learned on the specified ports when the VLAN is untagged and the

destination MAC address is one of the following:

01000C-CCCCCC (CDP)

0180c2- 00000e (LLDP)

0180c2-000003 (EAPOL)
