I have used
The Catalyst 3548 uses the Cisco IOS command set, much like the Catalyst
2924XL.
You might want to look into the Catalyst 2948G (not 2948G-L3) for the
Catalyst OS command set. It works just like the Catalyst 5000 series
without an RSM. Keep in mind that the 2948G does not support ISL trunking
though; it only support 802.1Q trunking for your VLAN's).
This would be a much more cost effective than procuring a 5xxx series box.
