View Global LLDP Information

About this task

Use this procedure to view global LLDP information, to know which LLDP settings and parameters are configured.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display LLDP local system data:

    show lldp local-sys-data [med]

  3. Display the LLDP neighbor system information:

    show lldp neighbor [summary] [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

  4. Display the list of ports:

    show lldp port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

  5. Display the LLDP reception statistics:

    show lldp rx-stats [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

  6. Display the LLDP statistics:

    show lldp stats

  7. Display the LLDP transmission statistics:

    show lldp tx-stats [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Variable Definitions

The following table defines parameters for the show lldp command.

Variable

Value

local-sys-data

Displays the LLDP local system data.

neighbor [summary] [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays the LLDP neighbor system information. You can also view this on a specific port.

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

port [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays the LLDP administrative status of a port or all ports on the switch.

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

rx-stats [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays the LLDP reception statistics on all ports on the switch, or on a specific port.

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

stats

Displays the LLDP statistics.

tx-stats [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays the LLDP transmission statistics on all ports on the switch or on a specific port.

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
