Hi

You could connect using fibre from one of your 3448's fibre ports to one of the PC5324's combo ports, this would give you a gigabit uplink but you cannot add the 5324 to the stack.

Hope this helps

Should it work, if I use a copper cable from port 48 of one of the 3448 to port 24 of the 5324?. I suppose the uplink will work only at 100Mb, but could I use link agregation to use a pair of ports to increase bandwith to 200Mb?

Thanks

Hi

Yes you could do that, as you say just add your ports (maximum of 8) into your Link Aggregation Group (LAG) on both switches and this would give you your 200MB LAG. Remember, LAG's may or may not actually provide you with additional bandwidth it really depends on your traffic patterns. LAGs are great if your traffic is using different src/dst MAC pairs as each flow will use a different LAG member port but if your data is always using the same src/dst MAC pair then the flow will always traverse the same 1 member port so your bandwidth will not have increased. The below white paper explains how LAGs work in detail:-
