Additonal Interfaces on 2821

Unanswered Question
Oct 26th, 2007

Hi All,

I am relatively new to cisco and routers. My organization just purchased a cisco 2821 router. We would like to add two additional gigabit ethernet interfaces to it and connect to other subnets via Cat 5e or Cat 6 cabling. I was just wondering if it is possible to add two additional gigabit ethernet interface cards (HWIC's) and if so, what specific hardware we would need to purchase?



I have this problem too.

As you will be routing between the subnets, a software-based router may not guarantee full performances, you best choice would be to get a L3 switch for that, eg a 3560 or 3750 10/100 for the PCs and 4 SFP ports for high-speed routing.

Hope this helps, please rate post if it does!
