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. |
