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.
FIGURE 2-9. LLDP CONFIGURATION
Parameter description:
LLDP Parameters:
Tx Interval: The switch periodically transmits LLDP frames to its neighbors to make 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 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.
Tx Delay: If some configuration is changed (e.g. the IP address) a new LLDP frame is transmitted, but the time between the LLDP
frames will always be at least the value of Tx Delay seconds. Tx Delay cannot be larger than 1/4 of the Tx Interval value. Valid values
are restricted to 1–8192 seconds.
Tx Reinit: When a port is disabled, LLDP is disabled or the switch is rebooted, an LLDP shutdown frame is transmitted to the
neighboring units, signaling that the LLDP information isn’t valid anymore. Tx Reinit controls the amount of seconds between the
shutdown frame and a new LLDP initialization. Valid values are restricted to 1–10 seconds.
