Network > LLDP
The LLDP page provides configuration options for the Link Layer Discovery Protocol (LLDP). These options enable
LLDP to standardize relationships across devices in a multi-vendor network so that device information can be
advertised directly to connected peer-neighbor devices.
To configure LLDP:
1. Select the checkbox to enable LLDP.
2. Type the Transmit Interval. This time interval is how often the PDU advertises itself to any LLDP receivers
on the network. The PDU acts as an LLDP transmitter only.
3. Click Apply.
The LLDP packet transmits the Chassis ID (the MAC address), the Port ID ("eth0"), the time to live (the transmit
interval times four [by definition]).
Also transmitted is the system name (the SNMP system name or the system name in "show SNMP"), and the
system description (the STI production description [for example, "Sentry Switched CDU"]).
The table below shows the possible values included in the LLDP packet:
