[c-nsp] Gigabit aggregation switches

[Steve Francis]

Can anyone share experiences with WS-C3550-12T 
<http://www.cisco.com/en/US/products/hw/switches/ps646/products_data_sheet09186a00800913d0.html>, 
WS-C2970G-24TS-E 
<http://www.cisco.com/en/US/products/hw/switches/ps5206/products_data_sheet09186a0080197384.html> 
or WS-C2948G-GE-TX 
<http://www.cisco.com/en/US/products/hw/switches/ps606/products_data_sheet09186a00801cfafe.html>?

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
