The 3524XL needed to have trunks because a switch needs to trunk
In order to carry more than one vlan..such as data and voice..

The access/trunk functions in the 3550 were not available..

I know this has been discussed before, but for the
life of me I can't find my notes or recall what the
reason was for the XL switches needing to be
configured as trunk ports. On newer switches, access
(dynamic) ports work fine and dynamically form trunk.

Was it a hardware limitation of XL switches (L2 only,
etc) or something else? looking for difference.

Thanks in advance,
Erick
