Viewing switch information available for outbound advertisements

Syntax: 

show lldp info local-device [port-list]

Without the [port-list] option, displays the global switch information and the per-port information currently available for populating outbound LLDP advertisements.

With the [port-list] option, displays only the following port-specific information that is currently available for outbound LLDP advertisements on the specified ports:

  • PortType
  • PortId
  • PortDesc
NOTE:

This command displays the information available on the switch. Use the lldp config <port-list> command to change the selection of information that is included in actual outbound advertisements. In the default LLDP configuration, all information displayed by this command is transmitted in outbound advertisements.

In the default configuration, the switch information currently available for outbound LLDP advertisements appears similar to the display in the following example.

    The Management Address field displays only the LLDP-configurable IP addresses on the switch. (Only manually-configured IP addresses are LLDP-configurable.) If the switch has only an IP address from a DHCP or Bootp server, then the Management Address field is empty (because there are no LLDP-configurable IP addresses available.
