Configuring LLDP
9
Per device
You can change the maximum number of neighbors for which LLDP data will be retained for the
entire system.
For example, to change the maximum number of LLDP neighbors for the entire device to 26, enter
the following command.
BigIron RX(config)#lldp max-total-neighbors 26
Syntax: [no] lldp max-total-neighbors <value>
Use the [no] form of the command to remove the static configuration and revert to the default
value of 392.
where <value> is a number between 16 and 65536. The default number of LLDP neighbors per
device is 392.
Use the show lldp command to view the configuration.
Per port
You can change the maximum number of LLDP neighbors for which LLDP data will be retained for
each port. By default, the maximum number is four and you can change this to a value between
one and 64.
For example, to change the maximum number of LLDP neighbors to six, enter the following
command.
BigIron RX(config)#lldp max-neighbors-per-port 6
Syntax: [no] lldp max-neighbors-per-port <value>
Use the [no] form of the command to remove the static configuration and revert to the default
value of four.
where <value> is a number from 1 to 64. The default is number of LLDP neighbors per port is four.
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
