I would like to ask what security risks such an error has on the network and the storage itself, and whether the solution is to modify the broadcast domain or what

Hello, 

 

This means that the port has layer 2 reachability to its assigned broadcast domain and  it also has layer 2 reachability to at least one other broadcast domain.

 

Examine the physical connectivity and switch configuration to determine if it is incorrect.

Network Recommendations:

- Isolate the network ports e0M from the rest of the network - a management network is preferred
- Isolate the concerned network ports into a vlan
- Isolate the network traffic from the switches
Note: e0m port should not be merged with another broadcast domain
