Hi, I have connected the GBIC port on a 3508G-XL to a 2950 FastEthernhet port, however, the ports are not coming up. I have tried straight through and crossover cables. Please could someone advise wheter the 2 switches can be connected and using which cables.
Your advice is much appreciated.
You can't connect a 1000BaseT GBIC to a FastEthernet interface. The 1000BaseT GBIC's (WS-G5483) only operate at 1Gbps. You will need a 1000BaseT interface on your 2950 to connect it to, there are no other options with the 3508G-XL. I assume you have a 2950 that only has 10/100 FastEthernet interfaces?
