I have facing this problem for a very long time. Here the desc figure of the switch situation.
The problem is I have been trying to access the switch on the RIGHT(A3100) through network but cant ping it(172.16.1.2) from anywhere. But the switch on the LEFT(A5500) can be access like normal through ping even hp web access.Right now I can only access the RIGHT(A3100) switch through console.
As we can see both switch are connected through trunk port.
Here are some routing info from switch on the LEFT(A5500):
[Switch A5500]dis ip ro

And Here are routing info for switch on the RIGHT(A3100):
[Switch A3100]dis ip r

If you need more info just ask. I'm still new to this and not sure about the actual problem. Thanks in advance!
