Item Description
make sure the product of the TTL multiplier and the LLDP frame
transmission interval is less than 255 seconds for CDP-compatible LLDP to
work correctly with Cisco IP phones.
Trap Interval
Set the minimum interval for sending traps.
With the LLDP trapping function enabled on a port, traps are sent out of the port
to advertise the topology changes detected over the trap interval to neighbors.
By tuning this interval, you can prevent excessive traps from being sent when
topology is instable.
Reinit Delay
Set initialization delay for LLDP-enabled ports.
Each time the LLDP operating mode of a port changes, its LLDP protocol state
machine reinitializes. A configurable reinitialization delay prevents frequent
initializations caused by frequent changes to the operating mode. If you
configure the reinitialization delay, a port must wait the specified amount of time
to initialize LLDP after the LLDP operating mode changes.
Tx Delay
Set LLDP frame transmission delay.
With LLDP enabled, a port advertises LLDP frames to its neighbors both
periodically and when the local configuration changes. To avoid excessive
number of LLDP frames caused by frequent local configuration changes, an
LLDP frame transmission delay is introduced. After sending an LLDP frame, the
port must wait for the specified interval before it can send another one.
LLDP frame transmission delay must be less than the TTL to make sure the
LLDP neighbors can receive LLDP frames to update information about the
device you are configuring before it is aged out.
Tx Interval
Set the LLDP frame transmission interval.
If the product of the TTL multiplier and the LLDP frame transmission interval is
greater than 65535, the TTL carried in transmitted LLDP frames takes 65535
seconds. The likelihood exists that the LLDP frame transmission interval is
greater than TTL. You should avoid the situation, because the LLDP neighbors
will fail to receive LLDP frames to update information about the device you are
configuring before it is aged out.
