We're trying to set up some new cisco switches. These new cisco siwtches are replacing some old dell switches. The dell switches are tied together via fiber and are on opposite ends of the building.
At each workstation in the building, there is a network drop running into a cisco phone, then it goes out of the phone and into the PC.
The cisco phones are configured for VLAN 100. The default access VLAN is 1 (must be what the workstations are using). THe phones receive DHCP from a cisco 1841 router that is currently connect to the old dell switches.
We configured the new switches via the GUI so that it showed each port to be configured for Cisco Phone and PC, and we changed the VLANs for each accordingly (100 and 1, respectively).
However, when we changed out the switches the phones never came back up. We noticed that the port on the new cisco switch that was connected to a cisco 1841 router was disabled. A look into the console showed that it was err-disabled. What should we do to make this work?
