User Guidelines
• LLDP manages LAG ports individually. LLDP sends separate advertisements on each port in
a LAG. LLDP data received through LAG ports is stored individually per port.
• LLDP operation on a port is not dependent on STP state of a port. I.e. LLDP frames are sent
and received on blocked ports. If a port is controlled by 802.1X, LLDP operates only if the
port is authorized.
