Configuring LLDP

9

Use the show lldp command to view the configuration.

Enabling LLDP SNMP notifications and Syslog messages

SNMP notifications and Syslog messages for LLDP provide management applications with
information related to MIB data updates and general status.

When you enable LLDP SNMP notifications, corresponding Syslog messages are enabled as well.
When you enable LLDP SNMP notifications, the device will send traps and corresponding Syslog
messages whenever there are changes to the LLDP data received from neighboring devices.

LLDP SNMP notifications and corresponding Syslog messages are disabled by default. To enable
them, enter a command such as the following at the Global CONFIG level of the CLI.

BigIron RX(config)# lldp enable snmp notifications ports e 4/2 to 4/6

The above command enables SNMP notifications and corresponding Syslog messages on ports
4/2 and 4/6. By default, the device will send no more than one SNMP notification and Syslog
message within a five second period. If desired, you can change this interval.

Syntax: [no] lldp enable snmp notifications ports ethernet <slotnum/portnum> | all

You can list all of the ports individually, use the keyword to specify ranges of ports, or a combination
of both. To apply the configuration to all ports on the device, use the keyword all instead of listing
the ports individually.

Specifying the minimum time between SNMP traps and
Syslog messages

When SNMP notifications and Syslog messages for LLDP are enabled, the device will send no more
than one SNMP notification and corresponding Syslog message within a five second period. If
desired, you can throttle the amount of time between transmission of SNMP traps
(lldpRemTablesChange) and Syslog messages from five seconds up to a value equal to one hour
(3600 seconds).

NOTE

Because LLDP Syslog messages are rate limited, some LLDP information given by the system will
not match the current LLDP statistics (as shown in the show lldp statistics command output).

To change the minimum time interval between traps and Syslog messages, enter a command such
as the following.

BigIron RX(config)# lldp snmp-notification-interval 60

When the above command is applied, the LLDP agent will send no more than one SNMP
notification and Syslog message every 60 seconds.

Syntax: [no] lldp snmp-notification-interval <seconds>

where <seconds> is a value between 5 and 3600. The default is 5 seconds.
