Configuring for Network Management Applications

LLDP (Link-Layer Discovery Protocol)

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)

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 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.

Changing the Time-to-Live for Transmitted Advertisements. The

Time-to-Live value (in seconds) for all LLDP advertisements transmitted from

a switch is controlled by the switch that generates the advertisement, and

determines how long an LLDP neighbor retains the advertised data before
