3.8 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. The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Link Layer protocol in the Internet Protocol Suite used by net-
work 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.

3.8.1 LLDP Configuration
When you change LLDP configuration and the detail parameters, the settings will take effect immediately. This page enables you
to view and configure the current LLDP port settings.
to view and configure the current LLDP port settings.
Web Interface
To configure LLDP:
1. Click 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 Save.

Parameter Description
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 restricted to five to 32768
seconds.
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 two to 10 times.
