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
