Catalyst 3750 Smartport Roles

I have 4 stacks of Catalyst WS-C3750X-48T-L   switches for my LAN infrastructure, and they're all configured with multiple VLANs, QoS, etc. in conjunction with a Unified Communications system. On most of my client ports, I've applied the IP Phone+Desktop smartport roles, and likewise AP/Switch/Router roles for those devices.

My question is this-- is it appropriate to apply a smartport role on the switch ports connected to ASA devices (ie. can an ASA be treated as a switch or router)? If not, in addition to trunking, what other parameters should applied to those ports to optimally configure them?

You can treat the ASA as a router to all intents and purposes. Although you talk about trunking, are you trunking yout switch to the firewall ?

Okay, personally i would just configure it manually because it makes sense to only allow the vlans you need on the trunk link ie.

int gi0/1  <-- this connects to ASA

switchport mode trunk

switchport trunk encapsulation dot1q

switchport trunk allowed vlan WS-C3750X-24T-S   <vlans that are going to ASA>
