Huawei quidway s7700 - Optional) Performing a Cable Test on an Interface

Context
Do as follows on the S7700 where you need to enable port isolation.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
port-isolate mode { l2 | all }
The port isolation mode is set.
By default, ports are isolated on Layer 2 but can communicate on Layer 3.
Step 3 Run:
interface interface-type interface-number
The Ethernet interface view is displayed.
Step 4 (Optional) Run:
am isolate interface-type interface-number [ to interface-number ]
The Ethernet interface is isolated from another interface unidirectionally.
NOTE
After interface A is isolated from interface B unidirectionally, packets sent by interface A cannot reach
interface B, whereas packets sent from interface B can reach interface A.
Step 5 Run:
port-isolate enable [ group group-id ]
Port isolation is enabled.
NOTE
Ports in a port isolation group are isolated from each other, and ports in different port isolation groups can
communicate with each other. If group-id is not specified, a port is added to port isolation group 1.
