Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

Configuring Basic LLDP Per-Port Advertisement Content

In the default LLDP configuration, outbound advertisements from each port on the switch include both mandatory and optional data.

Mandatory Data. An active LLDP port on the switch always includes the mandatory data in its outbound advertisements. LLDP collects the mandatory data, and, except for the Remote Management Address, you cannot use LLDP commands to configure the actual data.

Chassis Type (TLV subelement)

Chassis ID (TLV)

Port Type (TLV subelement)

Port ID (TLV)

Remote Management Address (TLV; actual IP address is a subelement that can be a default address or a configured address)

Configuring a Remote Management Address for Outbound LLDP

Advertisements. This is an optional command you can use to include a specific IP address in the outbound LLDP advertisements for specific ports.

Syntax [ no ] lldp config < port-list> ipAddrEnable < ip-address>

Replaces the default IP address for the port with an IP address you specify. This can be any IP address configured in a static VLAN on the switch, even if the port does not belong to the VLAN configured with the selected IP address. The no form of the command deletes the specified IP address. If there are no IP addresses configured as management addresses, then the IP address selection method returns to the default operation. (Default: The port advertises the IP address of the lowest-numbered VLAN (VID) to which it belongs. If there is no IP address configured on the VLAN(s) to which the port belongs, and the port is not configured to advertise an IP address from any other (static) VLAN on the switch, then the port advertises an address of 127.0.0.1.)

Note: This command does not accept either IP addresses acquired through DHCP or Bootp, or IP addresses that are not configured in a static VLAN on the switch
