Yeah my mistake.. was a 2950 that couldn't do ISL as someone else pointed
out to me.

2900XL and 3500XL are exactly equivalent in this regard (and most other ways
too other than GBIC slots) - as long as you have the EN models with 8Mb -
I'd
advise putting any non-EN models with 4Mb in the trash.  Make sure you're on
12.0(5)WC17 and subject to the limitations (no rapid SPT, no extended vlan
IDs, 1Gbps simplex per port on 3508XL, etc etc) they've been a fine
workhorse.
