Hello mates. I just want to know if you've countered this issue. We have had a WS-C6509 (with WS-F6K-MSFC2 loaded )which had a problem on a WS-X6348-RJ-45. After the module was replaced, we had found a weird thing that happened on the MSFC as it displays System image file is "unknown:/c6msfc2-jsv-mz.121-13.E15.bin" in the show version.
I have made checks on the status of the Layer 2 and 3 device and found that everything is working yet its just weird to have an unknown state in the show version.
