show lldp port command parameters
Parameters and variables
Description
rx-stats
The LLDP receive statistics for the local port.
tx-stats
The LLDP transmit statistics for the local port.
pdu-tlv-size
The different TLV sizes and the number of TLVs
in an LLDPDU.
tx-tlv {dot1 | dot3 }
Display which TLVs are transmitted from the
local port in LLDPDUs:
•
dot1: displays status for 802.1 TLVs
•
dot3: displays status for 802.3 TLVs
To display the transmission status of the
optional management TLVs, include only the
tx-tlv parameter in the command.
neighbor { dot1 [vlan-names
| protocol-id] } |
[dot3] | [detail]
The port neighbor TLVs:
•
dot1: displays 802.1 TLVs:
— vlan-names: VLAN Name TLV
— protocol-id: Protocol Identity TLV
•
dot3: displays 802.3 TLVs
•
detail: displays all TLVs.
[neighbor-mgmt-addr]
The port neighbor LLDP management address.
LLDP configuration example
By default, LLDP is enabled for Tx and Rx on all switch ports. The default
value for the LLDP Tx interval is 30 seconds (LLDPDUs are sent at 30
seconds). With the default settings, only the mandatory TLVs are sent, but
the switch can receive any LLDP Core, DOT1, or DOT3 TLV from its peers.
