Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
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.
