Description

Sangfor HCI supports the LLDP protocol to the connected switch interface. It enables the network interface number, MTU, TTL, and other information of the peer devices directly connected to the interface can be obtained, which is effective for administrators to operate, maintain and locate faults in the switch.

Precautions

1. It only supports viewing LLDP information on a single physical network interface but does not support viewing LLDP information on aggregated interfaces and VLAN subnet interfaces.
2. If there are multiple VLANs on the trunk interface of the switch, only one VLAN can be displayed.
3. Some other brands’ switches will forward LLDP packets of other devices (e.g., Sundray switches), resulting in the obtained LLDP information that is not the information of the directly connected interface on the switch end.

Prerequisites

The connected switch has enabled the LLDP protocol.

Steps

1. Navigate to Nodes > Physical Interfaces, select a node, and click Advanced > Configure LLDP.

2. Select the network interface to obtain the peer device information and click the Enable button.

3. After LLDP is enabled, go back to the Physical interfaces, locate the corresponding physical network interface, and click the View LLDP button. Then, you can view the LLDP information transmitted by the network interface of the peer devices/switches.

• Device ID: The MAC address of peer devices/switches.

• Port ID: The port ID of peer devices/switches.

• TTL: Time to live, packet’s lifetime.

• Port Description: Custom description.

• OS Name: Name of the peer devices/switches.

• OS Feature: Mode of the peer devices/switches.
