2.3.17 Two Cascaded IAD132E(T)s Cannot Ping Each Other
Symptom
Two cascaded IAD132E(T)s cannot ping each other.
Cause
The possible causes are as follows:

The two IADs are connected through a direct-connect cable, but the cable-check function
is not enabled.

The network is disconnected or the power supply is faulty.

IP addresses are not in the same network segment.
Solution
Step 1 Run the cable-check enable command on the upstream IAD.
The two IADs can be cascaded through a crossover cable. If a direct-connect cable is used, you must
enable the cable-check function on the upstream IAD.
Step 2 Check whether network port indicators are normal.

If no, check the network cable and power supply.

If yes, go to Step 3.
Step 3 Verify that the IP addresses are in the same network segment.
Step 4 Check whether the fault is rectified.

If yes, the procedure ends.

If no, go to Step 5.
Step 5 Contact Huawei technical support.
