Parameters Concerning
LLDPDU Sending
ONFIGURATION
To do...
Specify the management
address and specify to send
the management address
through LLDPDUs
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.
To disable MAC/PHY configuration/status TLV sending, you need to disable
■
LLDP-MED capabilities TLV sending first.
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.
Enabling sending of LLDP-MED capabilities TLVs also enables sending of
■
MAC/PHY configuration/status TLVs.
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:

Remarks
Optional
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. Refer to
"VLAN Configuration" on
page 83.
Remarks
-
Either of the two is required.
Configuration performed in
Ethernet interface view
applies to the current port
only; configuration
performed in port group view
applies to all the ports in the
corresponding port group.
Optional
Disabled by default
