Problem Description

Multiple snmp services are configured in the cross-layer 3 mac acquisition. Some can be obtained, while others cannot. Click to view the currently obtained IP/MAC list and find that there is no corresponding information

Process——

  1. Check the configuration of the snmp service and find that the first and second configurations get the binding relationship error, while the following can get the binding relationship normally. After consulting the customer, these two have been abandoned.

  2. After deleting the two failed snmp services, you can see the corresponding binding relationship in the currently obtained IP/MAC list.

Root cause

  1. The logic of IAG obtaining MAC across three layers is to obtain one by one from top to bottom. The first one cannot be obtained, resulting in no matching downwards.

solution

Modify or delete the failed acquisition in the SNMP service configuration
