Definately not. The 3550 is an overpriced outdated product with moderate performance with way too small table sizes. For instance: The Summit48si handles 128k MAC addresses. The 3550 handles something like 6-15k. The Summit48si can do buffering when doing QoS/shaping, the 3550 does only policing. If you want to deliver a 2meg service over ethernet to a customer, this is a big issue. There is only one product in the 3550 line that is pricewise worth getting is the 3550-12G if you need to do L2 gig aggregation to 1gig uplink and you do not have many VLANs. There are three issues I see where the 3550 actually has a selling point: VRFs (even though they are too few) Q-in-Q (limited by the small mac table size) CEF (if you have very small routing table size and no broadcasts) -- Mikael Abrahamsson email: email@example.com
