Configuring LLDP

Step 3
Step 4
This example shows how to configure the global LLDP hold time to 200 seconds:
switch# configure terminal
switch(config)# lldp holdtime 200
switch(config)#
This example shows how to enable LLDP to send or receive the management address TLVs:
switch# configure terminal
switch(config)# lldp tlv-select management-address
switch(config)#
This example shows how to enable LLDP to send or receive IPv4 management address TLVs:
switch# configure terminal

switch(config)#
This example shows how to enable LLDP to send or receive IPv6 management address TLVs:
switch# configure terminal

switch(config)#

Information About LLDP Management TLV IP Addresses

You can use the LLDP management TLV to convey the system information of network devices to their
neighbors. The LLDP management TLV includes the management address, which can be used by remote
managers to obtain information related to the local device. Currently, by default, the IPv4 and IPv6 address
of the management port mgmt0 are sent in the management TLV.
Cisco NX-OS Release 6.0(2)U4(1) introduces support for two TLVs, IPv4 and IPv6.
You can explicitly specify the management IPv4 or IPv6 address to be sent in the LLDP management TLV.
This address can be one of the following:
• IPv4 or IPv6 address of a port
• IPv4 or IPv6 address of a VLAN (SVI)
The following rules are applied while selecting a management address to be sent in the LLDP management
TLV for IPv4:
• If the LLDP management v4 TLV is configured to be sent, and if the LLDP management IPv4 address

of a port is configured, the LLDP management IPv4 address configured on the port is used in the
management TLV of the LLDP protocol data unit (PDU) to be sent.
