lldp source-mac vlan vlan-id
By default, the source MAC address of LLDP frames is the MAC address of the egress
interface.
To use the MAC address of a Layer 3 Ethernet subinterface as the source MAC address, use
vlan-id
to specify the subinterface ID in Layer 3 Ethernet interface view.
Enabling generation of ARP or ND entries for received
management address TLVs
About generation of ARP or ND entries for received management address TLVs
This feature enables the device to generate an ARP or ND entry after receiving an LLDP frame
containing a management address TLV on an interface. The ARP or ND entry maps the advertised
management address to the source MAC address of the frame.
You can enable generation of both ARP and ND entries on an interface. If the management address
TLV contains an IPv4 address, the device generates an ARP entry. If the management address TLV
contains an IPv6 address, the device generates an ND entry.
Restrictions and guidelines
In Layer 2 Ethernet interface view, you must configure the interface to use the MAC address of a
VLAN interface instead of its own MAC address as the source MAC address of LLDP frames. This
ensures that the neighbor NE can generate correct ARP or ND entries.
In Layer 3 Ethernet interface view, you can specify an existing Layer 3 Ethernet subinterface as the
output interface in the generated ARP or ND entry. Make sure the Layer 3 Ethernet subinterface has
an IP address that can be used for communications with the neighbor device.

By default, generation of ARP or ND entries for received management address TLVs is
disabled on an interface.
In Layer 3 Ethernet interface view, the
vlan vlan-id
option specifies the ID of a Layer 3
Ethernet subinterface used as the output interface in the ARP or ND entry.
In Layer 2 Ethernet interface view, the
vlan vlan-id
option specifies the ID of the VLAN to
which the generated ARP or ND entry belongs. To prevent the ARP or ND entries from
overwriting each other, do not specify the same VLAN ID for different Layer 2 Ethernet
interfaces.
You can enable generation of both ARP and ND entries on an interface.
