The problem is the IBM 5494 Remote Control Unit can no longer connect to the AS/400 at our remote site.

This problem started after changing the connect on our (3) 3900 series token switch stacks.

The old config on the switch stacks was:

**************

**3900 Stack**(VTP Domain: Cisco A / VTP Mode:Client)

***************

|

| (Fiber Uplink)

|

**************

**3900 Stack**(VTP Domain: No domain defined / VTP Mode: Transparent)

***************

|

| (Fiber Uplink)

|

**************

**3900 Stack**(VTP Domain: Cisco A / VTP Mode:Client)

***************

The router was not changed at all. The only change was made on that middle switch stack.

Do you guys have any ideas???? Please let me know..

Re: 3900 Series token stacks and IBM 5494 Remote Control Unit.

Check the VTP configuration revision number and see if the new server has overwritten any of the previously available vlans.
