Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Changing the Minimum Interval for Successive Data Change
Notifications for the Same Neighbor.
If LLDP trap notification is enabled on a port, a rapid succession of changes
in LLDP information received in advertisements from one or more neighbors
can generate a high number of traps. To reduce this effect, you can globally
change the interval between successive notifications of neighbor data change.
Syntax setmib lldpnotificationinterval.0 -i < 1 - 3600 >
Globally changes the interval between successive traps
generated by the switch. If multiple traps are generated in the
specified interval, only the first trap will be sent. The
remaining traps will be suppressed. (A network management
application can periodically check the switch MIB to detect any
missed change notification traps. Refer to IEEE P802.1AB or
later for more information.) (Default: 5 seconds)
For example, the following command limits change notification traps from a
particular switch to one per minute.
ProCurve(config)# setmib lldpnotificationinterval.0 -i 60
lldpNotificationInterval.0 = 60
Configuring Per-Port Transmit and Receive Modes
These commands control advertisement traffic inbound and outbound on
active ports.
Syntax lldp admin-status < port-list > < txonly | rxonly | tx_rx | disable >
With LLDP enabled on the switch in the default configuration,
each port is configured to transmit and receive LLDP packets.
These options enable you to control which ports participate in
LLDP traffic and whether the participating ports allow LLDP
traffic in only one direction or in both directions.
txonly: Configures the specified port(s) to transmit LLDP pack-
ets, but block inbound LLDP packets from neighbor devices.
rxonly: Configures the specified port(s) to receive LLDP packets
from neighbors, but block outbound packets to neighbors.
tx_rx: Configures the specified port(s) to both transmit and
receive LLDP packets. (This is the default setting.)
disable: Disables LLDP packet transmit and receive on the
specified port(s).
