Here is the issue…We have a network with 5 vlans , and 15 endpoint switches (2950s). In two areas of the network, a port has been designated switchport access only to VLAN 10…that port then runs to a linksys hub, where the devices on that hub all go to vlan 10.
in two instances, I have attempted to replace that hub with another 2950, and changed the connecting ports to trunks with all vlans allowed. I then set the specific ports on the 2950 to the vlan I want.
In both instances, I lost complete connectivity. In one vlan it was just a straigh network with no AD, in the second one, it has an AD domain controller.
Can someone point me to something I may have missed? I know what I know of Cisco IOS through trial and error, and am by no means an expert.
