3-5 LLDP
The switch supports the LLDP. For current information on your switch model, The 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.
3-5.1 LLDP Configuration
You can configure LLDP detail parameters on a per-port basis and the settings will take effect
immediately. This page lets you inspect and configure the current LLDP port settings.
Web Interface
To configure LLDP:
1. Click System, LLDP, and LLDP Configuration.
2. Modify 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 Parameter descriptions:
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. The default is 30 seconds.
