Trunk from 2930m to 1920s no connect to management

[paolom007]

Hello all,
we have Aruba 2930m in the RZ and the floors 1920s.

Now we want to connect the connection to the floor switches via trunk.
As soon as we connect the 2nd line we have no access to the 1920s for management. Only when a cable is connected, we come to the web interface.
What is wrong.

Many Thanks

Sounds like a misconfigured link aggregation. When one of the two devices is misconfigured it can happen that half of the traffic does not work, while the other half works. It may look strange in the first place, but when you think about the load sharing algorythms it makes sense. 

So check the trunk configuration.
