Optional, the configuration
applies to the current port only.
By default, all types of LLDP
TLVs except location
identification TLV are sent.
Specify the management
address and specify to
send the management
address through LLDPDUs
lldp management-address-tlv
[
ip-address
]
Optional, the configuration
applies to the current port only.
By default, the management
address is sent through
LLDPDUs, and the
management address is the IP
address of the interface of the
VLAN with the least VLAN ID
among those permitted on the
port. If the IP address of the
VLAN interface is not
configured, IP address
127.0.0.1 is used as the
management address.
z
To enable MED related LLDP TLV sending, you need to enable LLDP-MED capabilities TLV
sending first. Conversely, to disable LLDP-MED capabilities TLV sending, you need to disable the
sending of other MED related LLDP TLVs.
z
To disable MAC/PHY configuration/status TLV sending, you need to disable LLDP-MED
capabilities TLV sending first.
z
When executing the
lldp tlv-enable
command, specifying the
all
keyword for basic LLDP TLVs
and organization defined LLDP TLVs (including IEEE 802.1 defined LLDP TLVs and IEEE 802.3
defined LLDP TLVs) enables sending of all the corresponding LLDP TLVs. For MED related LLDP
TLVs, the
all
keyword enables sending of all the MED related LLDP TLVs except location
identification TLVs.
z
Enabling sending of LLDP-MED capabilities TLVs also enables sending of MAC/PHY
configuration/status TLVs.
Enable LLDP Polling
With LLDP polling enabled, a device checks for the local configuration changes periodically. Upon
detecting a configuration change, the device sends LLDPDUs to inform the neighboring devices of the
change.
Follow these steps to enable LLDP polling:
