Information About LLDP Management TLV IP Addresses
• If the LLDP management v4 TLV is configured to be sent, and if the LLDP VLAN is configured:
• If the LLDP management v4 TLV is configured to be sent and if neither the LLDP management IPv4
address nor the LLDP VLAN is configured, the IPv4 address of the management port mgmt0 is used in
the management v4 TLV of the LLDP PDU to be sent.
• If the LLDP management v4 TLV has no IPv4 address configured, the interface port's MAC address is
sent in one TLV.
• If the LLDP management v4 TLV is not configured to be sent, no management TLV IPv4 address is
sent.
The following rules are applied while selecting a management address to be sent in the LLDP management
TLV for IPv6:
• If the LLDP management v6 TLV is configured to be sent, and if the LLDP management IPv6 address
of a port is configured, the LLDP management IPv6 configured on the port is used in the management
TLV of the LLDP protocol data unit (PDU) to be sent.
• If the LLDP management v6 TLV is configured to be sent, and if the LLDP VLAN is configured:
• If the LLDP management v6 TLV is configured to be sent and if neither the LLDP management IPv6
address nor the LLDP VLAN is configured, the IPv6 address of the management port mgmt0 is used in
the management v6 TLV of the LLDP PDU to be sent.
• If the LLDP management v6 TLV has no IPv6 address configured, the interface port's MAC address is
sent in one TLV.
• If the LLDP management v6 TLV is not configured to be sent, no management TLV IPv6 address is
sent.
The following are the TLV selection processes that are followed based on the IPv4 or IPv6 address configured:
• No IP address configured—The interface port's MAC address is sent in one TLV.
• Only IPv4 address configured—Two TLVs are sent. One has the IPv4 address and the other has the
interface port's MAC address. This process follows the rules applied while selecting a management
address to be sent in the LLDP management TLV for IPv4.
• Only IPv6 address configured—The IPv6 address is sent in one TLV. This process follows the rules
applied while selecting a management address to be sent in the LLDP management TLV for IPv6.
• Both IPv4 and IPv6 addresses configured—Two TLVs are sent. One has the IPv4 address and the other
has the IPv6 address. This process follows the rules applied while selecting a management address to
be sent in the LLDP management TLV for IPv4 and for IPv6.

• If the VLAN ID is specified and the SVI on it is operationally enabled, the SVI IPv4 address of
the VLAN ID is used in the management v4 TLV of the LLDP PDU to be sent.
• If the native VLAN is available and the SVI on it is operationally enabled, the SVI IPv4 address
of the native VLAN is used in the management v4 TLV of the LLDP PDU to be sent.
• If the VLAN ID is specified and the SVI on it is operationally enabled, the SVI IPv6 address of
the VLAN ID is used in the management v6 TLV of the LLDP PDU to be sent.
• If the native VLAN is available and the SVI on it is operationally enabled, the SVI IPv6 address
of the native VLAN is used in the management v6 TLV of the LLDP PDU to be sent.
