[c-nsp] 2924XL gotchas?

[Paul Cairney]

IIRC the non-Enterprise 2900's were not do1q vlan capable, if anyone has an IOS that allows this on the 4mb hardware im sure there are many people out there who would bite your hand off for it.

Extended range vlans is only avaialable on the enterprise ios for 2950 and more recent switches, not sure about the 3500s as they were around the same era as 2900s but with a greater feature set so may be a more viable option then a 2950-T if you need extended range vlans.
