Yes, you can create a trunked interface, and even include your firewall interfaces if you have a single switching fabric for the LAN. If you have business reasons where VLAN isolation is not sufficient, then you will have to have a link to each switching fabric. If you have 3 separate switches, you will need 3 separate trunks. Each trunk can be a single interface, and have multiple VLANs associated with it, but the general rule is one trunk to each separate switching fabric. The switch fabric needs to be able to support LACP if you are planning to use more than one link in your trunk.
