Changing the LLDP Transmit State

Types of Information Transmitted

© Copyright Lenovo 2016
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 630), 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 G8264 port from their MIB.
In addition, if LLDP is fully disabled on a port and then later re‐enabled, the G8264
will temporarily delay resuming LLDP transmissions on the port to allow the port
LLDP information to stabilize. The reinitialization delay interval can be globally
configured for all ports using the following command:
RS G8264(config)# lldp reinit­delay <interval>
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.
When LLDP transmission is permitted on the port (see "Enabling or Disabling
LLDP" on page 630), the port advertises the following required information in
type/length/value (TLV) format:
Chassis ID

 Port ID
 LLDP Time‐to‐Live
LLDP transmissions can also be configured to enable or disable inclusion of
optional information, using the following command (Interface Port mode):
RS G8264(config)# interface port 1
RS G8264(config­if)# [no] lldp tlv <type>
RS G8264(config­if)# exit
where type is an LLDP information option from Table
Table 45.
