How do I view LLDP neighbors

0

Run the display lldp neighbor [ interface interface-type interface-number ] command to view information about neighboring devices of all interfaces or a specified interface.

Run the display lldp neighbor brief command to view brief information about neighbors of the device.

What should I do if an S series switches fails to discover LLDP neighbors
If a Huawei S series switch (except the S1700) fails to discover LLDP neighbors, the solutions are as follows: 1. Ensure that LLDP is enabled globally on the local switch and not disabled on related interfaces. 2. Ensure that LLDP is enabled globally on the peer switch and not disabled on related interfaces. 3. Ensure that the BPDU processing function is enabled on the related interfaces on the local and peer switches, and no other policy is used to discard LLDP BPDUs.

Why cannot an S series switches obtain LLDP neighbor information through SNMP
On a Huawei S series switch (except the S1700), the LLDP module has two MIB files, that is, HUAWEI-LLDP-MIB.mib and LLDP-MIB.mib. In the default configuration of the switch, SNMP is only applicable to the objects in the internet tree. The objects such as neighbor information in LLDP-MIB.mib are not in the internet tree. Therefore, the SNMP MIB view needs to be set to ISO. Then, all the objects in the ISO view can be accessed through SNMP. To obtain LLDP neighbor information through SNMP, run the following commands on the switch: [HUAWEI]snmp-agent community read huawei123 mib-view iso-view [HUAWEI]snmp-agent community write huawei123 mib-view iso-view [HUAWEI]snmp-agent sys-info version all [HUAWEI]snmp-agent mib-view included iso-view iso

How do I add a neighboring GK on the SMC1.0?
In the node management module of the SMC1.0 web interface, select a GK (GK 1) and add another GK (GK2) as the neighboring GK of GK 1 in the route table. To establish the neighboring relationship, you also need to add GK 1 as the neighboring GK of GK2. Route prefix: indicates the number prefix routed to the neighboring GK. IP address: indicates the IP address of the peer GK. Use the default values of other parameters.
