How bizarre... Could this be true? Would that screw with any
etherchannels that were using ports 1-6?

Hi,
if i remember correctly, the 3508 has limited line rates of around
700mbit/s on the first 6 ports, only port 7 and 8 will do full 1gbit/s.
So you might add this to your list (or when i'm wrong, just ignore it ;)
Regards,
Sven

here is some data on the 3508G and 3550-12G and i've also included
some info on the 2960G-24TC. check out the values listed for both
the switch-fabric and forwarding-rate between the 3 switches. i'd
also note that the 3550-12G is 1.5 RU -- not sure if rack space is
an issue, but wanted to point that out.
not sure if that helps in your decision but the 2960G-24TC is also
another one that'll will double your port-density and provide more
throughput. all just depends on what which features you require.
