LLDP (Link-Layer Discovery Protocol)

advertisements. Attempting to use the CLI to configure LLDP with an IP address that is either not configured on a VLAN, or has been acquired by DHCP or Bootp results in the following error message.

xxx.xxx.xxx.xxx: This IP address is not configured or is a DHCP address.

Spanning-Tree Blocking. Spanning tree does not prevent LLDP packet transmission or receipt on STP-blocked links.

802.1X Blocking. Ports blocked by 802.1X operation do not allow transmission or receipt of LLDP packets.

Configuring LLDP Operation

In the default configuration, LLDP is enabled and in both transmit and receive mode on all active ports. The LLDP configuration includes global settings that apply to all active ports on the switch, and per-port settings that affect only the operation of the specified ports.

The commands in this section affect both LLDP and LLDP-MED operation. for information on operation and configuration unique to LLDP-MED, refer to “LLDP-MED(Media-Endpoint-Discovery)” on page 13-53.
