If SNMP trap notification is enabled, the notification messages can also appear in the system log.
This is enabled by default. To change whether the SNMP trap notifications for LLDP events appear
in the system log, use the following command:
Changing the LLDP Transmit State
When the port is disabled, or when LLDP transmit is turned off for the port using the LLDP
admin-status command options (see “Transmit and Receive Control” on page 346), a final LLDP
packet is transmitted with a time-to-live value of 0. Neighbors that receive this packet will remove
the LLDP information associated with the G8124 port from their MIB.
In addition, if LLDP is fully disabled on a port and then later re-enabled, the G8124 will temporarily
delay resuming LLDP transmissions on the port in order to allow the port LLDP information to
stabilize. The reinitialization delay interval can be globally configured for all ports using the
following command:
where interval is the number of seconds to wait before resuming LLDP transmissions. The range is
between 1 and 10. The default is 2 seconds.
Types of Information Transmitted
When LLDP transmission is permitted on the port (see “Enabling or Disabling LLDP” on
page 346), the port advertises the following required information in type/length/value (TLV)
format:
Chassis ID
Port ID
LLDP Time-to-Live
RS G8124(config)# [no] logging log lldp
RS G8124(config)# lldp reinit-delay <interval>
