If you use a HWIC-4ESW in a router that supports it, can those 4 ports be individually configured as Fast Ethernet 2/3/4, etc? (I'm a firewall guy, so bear with me :-) ) I'm getting confused by the "switch" aspect...
Basically, I just need more routable fast ethernet ports on the 3845. Is this the best solution?
Mike refer to this link..
The Cisco EtherSwitch network module and service module interfaces can be configured directly as Layer 3, or routed, ports by using the no switchport command and assigning an IP address directly to the port. Cisco Switchports on the HWIC do not support Layer 3 addresses natively; they must be assigned to a SVI and use a VLAN interface for Layer 3. Every switch port can be assigned to a unique VLAN, up to 15 VLANs maximum.
