[Antonio Soares]

Don't forget that the 3550's will reach end of support in May 2011:

Feature Navigator is wrong - as usual. 3550 does not have hw support for 
IPv6, therefore no support for it. No plan, according to BU (have this 
info via our account manager), to support 
IPv6 on these switches. Go for 3560 or 3750....
