Item Description
Trap Interval
Set the minimum interval for sending traps.
With the LLDP trapping function enabled on a port, traps are sent out 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
re-initializes. To prevent LLDP from being initialized too frequently at times of frequent
operating mode change, initialization delay is introduced. With this delay mechanism,
a port must wait for the specified interval before it can initialize LLDP after the LLDP
operating mode changes.
Tx Delay
Set LLDPDU transmit delay.
With LLDP enabled, a port advertises LLDPDUs to its neighbors both periodically and
when the local configuration changes. To avoid excessive number of LLDPDUs caused
by frequent local configuration changes, an LLDPDU transmit delay is introduced. After
sending an LLDPDU, the port must wait for the specified interval before it can send
another one.
IMPORTANT:
LLDPDU transmit delay must be less than the TTL to make sure that the LLDP neighbors can
receive LLDPDUs to update information about the device you are configuring before it is
aged out.
Tx Interval
Set the LLDPDU transmit interval.
IMPORTANT:
If the product of the TTL multiplier and the LLDPDU transmit interval is greater than 65535,
the TTL carried in transmitted LLDPDUs takes 65535 seconds. The likelihood exists that the
LLDPDU transmit interval is greater than TTL. You should avoid the situation, because the
LLDP neighbors will fail to receive LLDPDUs to update information about the device you are
configuring before it is aged out.
Displaying LLDP information for a port
1. Select Network > LLDP from the navigation tree to enter the Port Setup tab, as shown in Figure
165 .
2. In the port list click a port name to display its LLDP information at the lower half of the page. The
Local Information tab is displayed by default, as shown in
Figure 169 .
