Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

Configuring Global LLDP Packet Controls

The commands in this section configure the aspects of LLDP operation that

apply the same to all ports in the switch.

Enabling or Disabling LLDP Operation on the Switch. Enabling LLDP

operation (the default) causes the switch to:

■ Use active, LLDP-enabled ports to transmit LLDP packets describing itself

to neighbor devices.

■ Add entries to its neighbors table based on data read from incoming LLDP

advertisements.

For example, to disable LLDP on the switch:

ProCurve(config)# no lldp run

Changing the Packet Transmission Interval. This interval controls how

often active ports retransmit advertisements to their neighbors.

Syntax [ no ] lldp run

Enables or disables LLDP operation on the switch. The no form

of the command, regardless of individual LLDP port

configurations, prevents the switch from transmitting

outbound LLDP advertisements, and causes the switch to drop

all LLDP advertisements received from other devices. The

switch preserves the current LLDP configuration when LLDP

is disabled. After LLDP is disabled, the information in the

LLDP neighbors database remains until it times-out. (Default:

Enabled)

Syntax lldp refresh-interval < 5 - 32768 >

Changes the interval between consecutive transmissions of

LLDP advertisements on any given port. (Default: 30 seconds)

Note: The refresh-interval must be greater than or equal to

(4 x delay-interval). (The default delay-interval is 2). For example,

with the default delay-interval, the lowest refresh-interval you can

use is 8 seconds (4 x 2 = 8). Thus, if you want a refresh-interval of

5 seconds, you must first change the delay interval to 1 (that is,

4 x 1 < 5). If you want to change the delay-interval, use the setmib

command.
