Displaying LLDP Neighbors Information
The LLDP Neighbors Information page displays information that was received from neighboring devices.
After timeout (based on the value received from the neighbor Time To Live TLV during which no LLDP PDU was received from a neighbor), the information is deleted.
To view the LLDP neighbors information:
- Click Administration > Discovery - LLDP > Neighbors Information. The LLDP Neighbors Information page opens.
This page displays the following fields:
- Local Port--Number of the local port to which the neighbor is connected.
- Chassis ID Subtype--Type of chassis ID (for example, MAC address).
- Chassis ID--Identifier of the 802 LAN neighboring device's chassis.
- Port ID Subtype--Type of the port identifier that is shown.
- Port ID--Identifier of port.
- System Name--Published name of the switch.
- Time to Live--Time interval (in seconds) after which the information for this neighbor is deleted.
- Select a local port, and click Details. The Neighbors Information page opens.
This page displays the following fields:
