If anyone can help me with this issue it would be greatly appreciated. I'm a new Sys Admin working in a Cisco shop. In our headquarters they had moved from using a router to a Cisco 9400 which also handles routing. Currently we have a line connection to one of our branches that is working but they wanted to upgrade the bandwidth and the carrier has installed a new service line. They provisioned the line and gave us instruction it was to be a tagged line for vlan#55. The plan had been to do the changeover early in the morning so it would not cause an outage. We tried this morning and failed. No access whatsoever.
I configured a new port on the 9400 switch similar to what is there and working now. I also configured the router interface as well. Here are the configs: **Please note that the IP had to be changed back on the switch so it would work on the old line for today.
9400#show int g9/0/48 switchport

9400(config-if)#ip add 10.10.10.53 255.255.255.252
On the Branches router which is an old 2811 the config is:
interface FastEthernet0/1
description EVPL to HQ
no ip address
ip flow ingress
duplex full
speed 100
interface FastEthernet0/1.1

encapsulation dot1Q 55
ip address 10.10.10.54 255.255.255.252
Thank you in advance.
