8 LLDP configuration

LLDP configuration

This section describes how to enable and configure LLDP.

Table 44 lists the LLDP global-level tasks and the default behavior/value for each task.

LLDP global configuration tasks and default behavior /value

Global task	Default behavior / value when LLDP is enabled
Enabling LLDP on a global basis	Disabled
Specifying the maximum number of LLDP	Automatically set to 392 neighbors per device
neighbors per device
Specifying the maximum number of LLDP	Automatically set to 4 neighbors per port
neighbors per port
Enabling SNMP notifications and Syslog messages	Disabled
Changing the minimum time between SNMP traps	Automatically set to 2 seconds when SNMP notifications and
and Syslog messages	Syslog messages for LLDP are enabled
Enabling and disabling TLV advertisements	When LLDP transmit is enabled, by default, the Brocade
	device will automatically advertise LLDP capabilities, except
	for the system description, VLAN name, and power-via-MDI
	information, which may be configured by the system
	administrator.
	Also, if desired, you can disable the advertisement of
	individual TLVs.
Changing the minimum time between LLDP	Automatically set to 2 seconds
transmissions
Changing the interval between regular LLDP	Automatically set to 30 seconds
transmissions
Changing the holdtime multiplier for transmit TTL	Automatically set to 4
Changing the minimum time between port	Automatically set to 2 seconds
reinitializations

LLDP configuration notes and considerations

•LLDP is supported on Ethernet interfaces only.

•If a port is 802.1X-enabled, the transmission and reception of LLDP packets will only take place while the port is authorized.

•Cisco Discovery Protocol (CDP) and Brocade Discovery Protocol (FDP) run independently of LLDP. Therefore, these discovery protocols can run simultaneously on the same device.

•By default, the Brocade device limits the number of neighbors per port to four, and staggers the transmission of LLDP packets on different ports, in order to minimize any high-usage spikes to the CPU.

•By default, the Brocade device forwards

•Ports that are in blocking mode (spanning tree) can still receive LLDP packets from a forwarding port.

•Auto-negotiation status indicates what is being advertised by the port for 802.3 auto-negotiation.
