4LLDPLLDPLink Layer Discovery Protocol (LLDP) enables a station to advertise its capabilities and to discoverother LLDP-enabled stations in the same 802 LAN. An LLDP agent can transmit and receiveinformation to and from another LLDP agent located on an adjacent device, but it cannot solicitinformation from another LLDP agent, nor can it acknowledge information received from anotherLLDP agent.LLDP debug commandsThis section describes the LLDP-related debug commands.debug lldpSyntax: debug lldpThis command displays information about LLDP port state changes. Command output resemblesthe following example.Brocade# debug lldpLLDP: All Ports: debugging is onNov 17 19:29:37 LLDP port 1/1 : Tx INIT -> INIT ; Rx WAIT_PORT_OPER ->WAIT_PORT_OPERNov 17 19:29:37 LLDP: Ethernet: 1/1 tx_enabled = 1 rx_enabled = 1Nov 17 19:29:37 LLDP port 1/2 : Tx INIT -> INIT ; Rx WAIT_PORT_OPER ->WAIT_PORT_OPERNov 17 19:29:37 LLDP: Ethernet: 1/2 tx_enabled = 1 rx_enabled = 1Nov 17 19:29:37 LLDP port 1/3 : Tx INIT -> IDLE ; Rx INIT -> WAIT_FOR_FRAMENov 17 19:29:37 LLDP: Ethernet: 1/3 tx_enabled = 1 rx_enabled = 1Nov 17 19:29:44 LLDP event : Packet recieved on port: 1/1Nov 17 19:29:44 LLDP event : Packet recieved on port: 1/2Nov 17 19:29:44 LLDP event : Packet recieved on port: 1/3Nov 17 19:30:08 LLDP event : poll timer triggeredNov 17 19:30:08 LLDP event : poll timer triggered, calling timer handlerNov 17 19:30:08 LLDP event : Packet sent from port: 1/1Nov 17 19:30:08 LLDP event : called transmit PDU on port 1/1Nov 17 19:30:08 LLDP event : poll timer triggeredNov 17 19:30:08 LLDP event : poll timer triggered, calling timer handlerNov 17 19:30:08 LLDP event : Packet sent from port: 1/2Nov 17 19:30:08 LLDP event : called transmit PDU on port 1/2Nov 17 19:30:08 LLDP event : poll timer triggeredNov 17 19:30:08 LLDP event : poll timer triggered, calling timer handlerNov 17 19:30:08 LLDP event : Packet sent from port: 1/3Nov 17 19:30:08 LLDP event : called transmit PDU on port 1/3debug lldp portSyntax: debug lldp port ethernet The ethernet parameter limits the display of LLDP port state change information to thespecific Ethernet port. Command output resembles the following example.Brocade# debug lldp port ethernet 1/1LLDP debug port set to 1/1.Nov 17 19:29:37 LLDP port 1/1 : Tx INIT -> INIT ; Rx WAIT_PORT_OPER ->WAIT_PORT_OPERNov 17 19:29:37 LLDP: Ethernet: 1/1 tx_enabled = 1 rx_enabled = 1Nov 17 19:29:44 LLDP event : Packet recieved on port: 1/1Nov 17 19:30:08 LLDP event : poll timer triggered104 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
