[c-nsp] Gigabit aggregation switches

[Dave Breiland]

Correct me if I'm wrong, but I believe the only thing you really gain with
the 3550-12T is the possibility for Layer3 switching.  I haven't personally
tried it, but I believe you can route between VLANS on the 3550's.  

I recently implemented a 2970G-24 and have had no issues with it as of yet.
If I recall correctly, the 2970G-24 has a 24Gbps backplane, which seems most
important for your situation.  

The nice thing about the 2948G's that I have (48 port 10/100 w/ 2 GBICs) is
that it runs the CatOS... which I personally prefer.

Hopefully that gives you some info to think about and research.

Dave

Can anyone share experiences with WS-C3550-12T

I've heard people say good things about 3550-12T, but is there anything 
wrong with the 2970, which gives me a lot more gig ports for about 50% 
the cost?

All I really want is a switch that does rapid spanning tree, ssh, and 
basic layer2 vlan stuff, while giving me more than the 2 gig ports you 
normally get on other 3550s.

Of course, the real issue is I want the switch to be stable.
Comments?
Thanks
