Issue Description

MAC acquisition across L3 network unable to gain mac and IP address.

Handling Process

1. Checked the basic configuration is correct and core switch’s configuration no issue.

2. During packet capture, found out the IP packet fragmented.


Root Cause

This is because Mac address reply from Core switch too many and caused the packet become larger, IAM will not manage these type of fragmented packet and caused IAM unable to gain the mac address and IP address.

Solution

Limit the number of max Mac addresses from 100 to 50.
