Time-to-Live for Transmitted Information

The transmitted LLDP information is held by remote systems for a limited time. A time-to-live parameter allows the switch to determine how long the transmitted data should be held before it expires. The hold time is configured as a multiple of the configured transmission interval.

RS G8124(config)# lldp holdtime-multiplier <multiplier>

where multiplier is a value between 2 and 10. The default value is 4, meaning that remote systems will hold the port’s LLDP information for 4 x the 30-secondmsgtxint value, or 120 seconds, before removing it from their MIB.

Trap Notifications

If SNMP is enabled on the G8124 (see “Using Simple Network Management Protocol” on page 35), each port can be configured to send SNMP trap notifications whenever LLDP transmissions are sent. By default, trap notification is disabled for each port. The trap notification state can be changed using the following commands (Interface Port mode):

RS G8124(config)# interface port 1

RS G8124(config-if)# [no] lldp trap-notification

RS G8124(config-if)# exit

In addition to sending LLDP information at scheduled intervals, LLDP information is also sent when the G8124 detects relevant changes to its configuration or status (such as when ports are enabled or disabled). To prevent the G8124 from sending multiple trap notifications in rapid succession when port status is in flux, a global trap delay timer can be configured.

The trap delay timer represents the minimum time permitted between successive trap notifications on any port. Any interval-driven or change-driven trap notices from the port will be consolidated until the configured trap delay expires.

The minimum trap notification interval can be configured using the following command:

RS G8124(config)# lldp trap-notification-interval <interval>

where interval is the minimum number of seconds permitted between successive LLDP transmissions on any port. The range is 1 to 3600. The default is 5 seconds.
