Hi everyone
Earlier today I did an IOS upgrade for an ISP. They are using a Cisco 3640 router to handle all the routing done on their network. Each module bay is occupied by an Ethernet module of some type. Two contain single 10Mbit Ethernet modules, one has a 4 port 10Mbit module, and one has a FastEthernet 10/100Mbit module (part number 1FE-TX). Here's the issue. The IOS they were running prior to the upgrade was 12.0(5). After the upgrade, it was 12.1(8). When it came back up on the new IOS, the FastEthernet reported the line protocol as down!
Now, in my own company, we had a long standing issue with Cisco on one of our 3660's where a 4 port BRI card didn't work until a specific IOS image was loaded. I thought that might be the problem in this case.
Stranger still, I connected a laptop directly to the FastEthernet port using a X-over, and the interface protocol came up. I assigned it a temporary IP, and it was soon pingable as well, yet when I tried again to connect it to the original connection (their Internet access via Ethernet from UUNet Canada), the protocol went down again.
Temporarily, I moved the UUNet provided Internet connection to an unused 10Mbit Ethernet port, and all is fine, but I would like to get the FastEthernet interface working. Does anyone have an ideas or experience with this issue?
