Configuring Lldp Trapping - HP 5120 EI Series Lan Switching Configuration Manual

CAUTION:
The maximum TTL value that CDP allows is 255 seconds. To make CDP-compatible LLDP work properly
with Cisco IP phones, be sure that the product of the TTL multiplier and the LLDPDU transmit interval is less
than 255 seconds.
CDP-compatible LLDP operates in one of the follows modes:
• TxRx—CDP packets can be transmitted and received.
Disable—CDP packets cannot be transmitted or received.
•
To make CDP-compatible LLDP take effect on specific ports, first enable CDP-compatible LLDP globally,
and then configure CDP-compatible LLDP to operate in TxRx mode.
To enable LLDP to be compatible with CDP:
Step
1. Enter system view.
2. Enable CDP compatibility
globally.
3. Enter Ethernet interface view
or port group view.
4. Configure CDP-compatible
LLDP to operate in TxRx
mode.

Configuring LLDP trapping

LLDP trapping notifies the network management system (NMS) of events such as newly-detected
neighboring devices and link malfunctions.
LLDP traps are sent periodically, and the interval is configurable. To prevent excessive LLDP traps from
being sent when the topology is unstable, set a trap transmit interval for LLDP.
To configure LLDP trapping:
Step
1. Enter system view.
2. Enter Ethernet interface view or port
group view.
3. Enable LLDP trapping.
4. Return to system view.
5. Set the LLDP trap transmit interval.
