Setting LLDP Properties
The LLDP Properties page enables entering LLDP general parameters. These include enabling/disabling the feature globally and setting timers.
To enter LLDP properties:
- Click Administration > Discovery - LLDP > Properties. The LLDP Properties page opens.
- Enter the parameters.
- LLDP Status--Select to enable LLDP on the switch (selected by default).
- LLDP PDU Action--If LLDP is not enabled, select the action to be taken if a packet that matches the selected criteria is received:
- TLV Advertise Interval--Enter the rate in seconds at which LLDP advertisement updates are sent or use the default.
- Topology Change System Log Notification Interval--Enter the minimum time interval between system log notifications.
- Hold Multiplier--Enter the amount of time that LLDP packets are held before the packets are discarded, measured in multiples of the TLV Advertise Interval. For example, if the TLV Advertise Interval is 30 seconds, and the Hold Multiplier is 4, then the LLDP packets are discarded after 120 seconds.
- Reinitializing Delay--Enter the time interval in seconds that passes between disabling and reinitializing LLDP, following an LLDP enable/disable cycle.
- Transmit Delay--Enter the amount of time in seconds that passes between successive LLDP frame transmissions due to changes in the LLDP local systems MIB.
For a description of LLDP MED, refer to the LLDP MED Network Policy section.
- In the Fast Start Repeat Count field, enter the number of times LLDP packets are sent when the LLDP-MED Fast Start mechanism is initialized. This occurs when a new endpoint device links to the switch.
- Click Apply. The LLDP properties are added to the Running Configuration file.
