Configuring LLDP
20
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.
PowerConnect(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.
PowerConnect(config)#lldp enable snmp notifications ports e 2 to 6
The above command enables SNMP notifications and corresponding Syslog messages on ports 2
and 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. Refer to “Specifying the
minimum time between SNMP traps and syslog messages” on page 547.
Syntax: [no] lldp enable snmp notifications ports ethernet <port-list> | all
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).
