LLDP configuration
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.
Brocade(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 463.
Syntax: [no] lldp enable snmp notifications ports ethernet <port-list> | all
For port-list , specify the ports in one of the following formats:
• FWS, FCX and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• FESX compact switches – 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.
Brocade(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.
Changing the minimum time between LLDP transmissions
The LLDP transmit delay timer limits the number of LLDP frames an LLDP agent can send within a
specified time frame. When you enable LLDP, the system automatically sets the LLDP transmit
delay timer to two seconds. If desired, you can change the default behavior from two seconds to a
value between 1 and 8192 seconds.
