Advanced LLDP configuration
The configuration procedure above and the defaults for other settings suit most networks. Use the following
commands for fine tuning if necessary.
Timer intervals should be long enough not to create unnecessarily high numbers of advertisements when there
are topology changes. However, be aware that if the intervals are long, a neighbor’s information can continue
to be stored after its information has changed, or after it is disconnected.
12.
awplus#
Enter Configuration mode.
13.
awplus(config)#
interface <port-list>
Enter Interface Configuration mode for the switch
ports.
14.
awplus(config-if)#
Override the default LLDP management address
advertised through this port if required. This must
be an IPv4 address that is already configured on
the device. To see the management address that
will be advertised, use the
15.
awplus(config-if)#
By default, SNMP notifications are not transmitted.
Enable them for these ports if required. (SNMP
LLDP traps (notifications) must also be enabled.)
16.
awplus(config-if)#
Return to Global Configuration mode.
17.
awplus(config)#
The transmit interval determines how often
regular LLDP transmits advertisements from each
port. The transmit interval must be at least four
times the transmission delay.
Default: 30 seconds
18.
awplus(config)#
lldp notification-interval <5-
The notification interval determines the minimum
interval between sending SNMP notifications
(traps).
Default: 5 seconds
19.
awplus(config)#
A series of successive changes over a short period
of time can trigger the agent to send a large
number of LLDPDUs. To prevent this, there is a
transmission delay timer. This establishes a
minimum length of time that must elapse
between successive LLDP transmissions. The
transmission delay cannot be greater than a
quarter of the transmit interval.
Default: 2 seconds
20.
awplus(config)#
Reinitialization delay timer determines the
minimum time after disabling LLDP on a port
before it can reinitialize.
Default: 2 seconds
21.
awplus(config)#
The transmit interval is multiplied by the holdtime
multiplier to give the Time To Live (TTL) value that
is advertised to neighbors.
Default: 4
22.
awplus(config)#
Return to Privileged Exec mode.
Clear data
If necessary, you can clear either neighbor information or LLDP statistics for particular ports or all ports.
23.
awplus#
Clear the information from the table of neighbor
information.
24.
awplus#
clear lldp statistics [interface
Clear LLDP statistics (packet and event counters).
