HP Comware 5 Debug Manual Vol 2

Table 225 Output from the debugging lldp fsm command
• Field
• Description
•
Receive state
machine
change from
state1 state to
state2 state
•
The receive state machine changed from state 1 to state 2.
State 1 and state 2 can be:
• LLDP_RX_WAIT_PORT—The port is not enabled.
• LLDP_RX_DEL_AGEDINFO—An aged neighbor information is removed.
• LLDP_RX_INIT—The port is initialized for receiving packets.
• LLDP_RX_WAIT_FRAME—The port is waiting for receiving packets.
• LLDP_RX_FRAME—The port is receiving and resolving packets.
• LLDP_RX_DEL_INFO—The port received shutdown packets from the
remote end and deleted the neighbor information.
• LLDP_RX_DEL_AGEDINFO—The port is updating the neighbor
information.
•
Transmit state
machine
change from
state1 state to
state2 state
•
The transmit state machine changed from state 1 to state 2.
State 1 and state 2 can be:
• LLDP_TX_WAIT_PORT—The port is not enabled.
• LLDP_TX_INIT—The port is initialized for transmitting packets.
• LLDP_TX_IDLE—The port is idle.
• LLDP_TX_SHUTDOWN_FRAME—The port is transmitting shutdown
packets.
• LLDP_TX_INFO_FRAME—The port is transmitting packets.
Examples
The output in the following examples is generated under the following conditions:
•
Device A is connected to Device B through Ethernet 1/1.
•
LLDP is enabled globally on the devices and on the connecting ports.
# Enable debugging for LLDP state machines on Device A.

// The LLDP transmit state machine transitioned from the TC_IDLE state to the TX_INFO_FRAME state,
and then to the TX_IDLE state. The LLDP receive state machine transitioned from the
RX_WAIT_FOR_FRAME state to the RX_FRAME state, and then to the RX_WAIT_FOR_FRAME state.
