HP Displaying LLDP information for a port

Item	Description
	Set the TTL multiplier.
	The TTL TLV carried in an LLDPDU determines how long the device information
	carried in the LLDPDU can be saved on a recipient device. You can configure
	the TTL of locally sent LLDPDUs to determine how long information about the
	local device can be saved on a neighbor device by setting the TTL multiplier.
	The TTL is expressed as TTL multiplier × LLDP frame transmission interval.
TTL Multiplier	When you configure the TTL multiplier, follow these guidelines:
	• 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.
	• Because the maximum TTL allowed by CDP is 255 seconds, you must 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.
	Set the minimum interval for sending traps.
Trap Interval	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.
	Set initialization delay for LLDP-enabled ports.
	Each time the LLDP operating mode of a port changes, its LLDP protocol state
Reinit Delay	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.
	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
Tx Delay	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.
	Set the LLDP frame transmission interval.
	If the product of the TTL multiplier and the LLDP frame transmission interval is
Tx Interval	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.

Displaying LLDP information for a port

1.From the navigation tree, select Network > LLDP. By default, the Port Setup tab is displayed.

2.On the port list, click a port name to display its LLDP information at the lower half of the page.
