Publication Date:  2012-07-23 Views:  194 Downloads:  0
Issue Description
Multiple NEs have been added to the VSM. Choose File > Discovery > Link to discover links. However, after the operation is complete, LLDP links fail to be discovered
Alarm Information
None
Handling Process

1.         Run the system-view command to enter the system view.

2.         Run the display current-configuration | include lldp command to check whether LLDP is enabled and the management IP address of the NE is registered with the VSM.

3.         Run the display current-configuration | include snmp-agent command to check whether the LLDP-related SNMP parameters are correct.

Root Cause
LLDP is not enabled on the NE or the management IP address of the NE is incorrect.

The LLDP-related SNMP parameters are incorrect.

Suggestions

1.         Set the LLDP parameters of an NE. Among the parameters, 192.168.100.101 is the management IP address of the NE that is registered with the VSM.

[NE]lldp enable
[NE]lldp management-address 192.168.100.101

 

2.         Set the LLDP-related SNMP parameters.

[NE]snmp-agent community read   public mib-view lldp
[NE]snmp-agent community write   private mib-view lldp
[NE]snmp-agent mib-view included lldp iso
[NE]snmp-agent mib-view included lldp std
