Configuring LLDP
24
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 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. Refer to “Specifying
the minimum time between SNMP traps and syslog messages” on page 697.
Syntax: [no] lldp enable snmp notifications ports ethernet <port-list> | all
For <port-list>, specify the ports in the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
You can list all of the ports individually, use the keyword to 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.
PowerConnect(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.
