LLDP
The switch supports LLDP (Link Layer Discovery Protocol). LLDP provides a standards-based method for enabling
switches to advertise themselves to adjacent devices and to learn about adjacent LLDP devices. LLDP is a
vendor-neutral Link Layer protocol in the Internet Protocol Suite used by network devices for advertising their
identity, capabilities, and neighbors on a IEEE 802 local area network, principally wired Ethernet. The protocol is
formally referred to by the IEEE as “Station and Media Access Control Connectivity Discovery” specified in
standards document IEEE 802.1AB.
LLDP Configuration
This page lets you view and configure the current LLDP settings. You can configure LLDP and detailed per-port
parameters; the settings will take effect immediately.
To configure LLDP:
1.
Click System, LLDP and LLDP Configuration.
2.
Modify the LLDP timing parameters.
3.
Set the required Mode for transmitting or receiving LLDP messages.
4.
Specify the information to include in the TLV field of advertised messages.
5.
Click Apply.

LLDP Parameters
Tx Interval
: The switch periodically transmits LLDP frames to its neighbors for having the network discovery
information up-to-date. The interval between each LLDP frame is determined by the Tx Interval value. Valid
values are 5 - 32768 seconds.
Tx Hold
: Each LLDP frame contains information about how long the information in the LLDP frame will be
considered valid. The LLDP information valid period is set to Tx Hold multiplied by Tx Interval seconds. Valid
values are restricted to 2 - 10 times.
