Any ideas on the following:- I have Cisco 3548XL and a Cisco 2960G, I am trying to link the both with a WS-G5483 GBIC Module. The 2960G picks it up no problem and the led indicate so. The 3548XL shows the module in the graphical interface and in show interface it also seeing the correct media type ( media type T) but interface is down/down, also there is no LED activity on the 3548XL. The 3548XL is runing IOS 12.0(5.3)WC1.
Hope some one can help?
You need at least 12.0(5)WC3b to support WS-G5483 on XL switch. Try to upgrade the switch and I believe it should work.
