LLDP Operating Rules
Port Trunking. LLDP manages trunked ports individually. That is, trunked ports are configured
individually for LLDP operation, in the same manner as non-trunked ports. Also, LLDP sends separate
advertisements on each port in a trunk, and not on a per-trunk basis.
IP Address Advertisements. In the default operation, if a port belongs to only one static VLAN,
then the port advertises the lowest-order IP address configured on that VLAN. If a port belongs to
multiple VLANs, then the port advertises the lowest-order IP address configured on the VLAN with
the lowest VID. If the qualifying VLAN does not have an IP address, the port advertises the base MAC
address of the device as its IP address. For example, if the port is a member of the default VLAN
(VID = 1), and there is an IP address configured for the default VLAN, then the port advertises this
IP address. In the default operation, the IP address that LLDP uses can be an address acquired by
DHCP or Bootp.
Spanning-Tree Blocking. Spanning tree does not prevent LLDP packet transmission on STP-
blocked links.
802.1X Blocking. Ports blocked by 802.1X operation do not allow transmission of LLDP packets.
