FIGURE 2 LLDP connectivity
General operating principles
LLDP use the services of the Data Link sub layers, Logical Link Control and Media Access Control,
to transmit and receive information to and from other LLDP Agents (protocol entities that
implement LLDP).
LLDP is a one-way protocol. An LLDP agent can transmit and receive information to and from
another LLDP agent located on an adjacent device, but it cannot solicit information from another
LLDP agent, nor can it acknowledge information received from another LLDP agent.
Operating modes
When LLDP is enabled on a global basis, by default, each port on the Brocade device will be
capable of transmitting and receiving LLDP packets. LLDP supports the following operating modes
on physical interfaces:
Transmit and Receive LLDP information. (System default)
Transmit LLDP information only
Receive LLDP information only
