I am trying to find out the main difference between the HWIC-1FE and HWIC-4ESW cards.
Also I have a cisco 2811 router that is configured with one Fastethernet connected to DSL and the other port connects to mt LAN and METRO (using subinterfaces), is this the best practice?
HWIC-4ESW is the 4-port single-wide 10/100BaseT Ethernet switch HWIC. The 4ESW is a L2 switch and is cost effective.
HWIC-1FE is 1-port Fast Ethernet HWIC. The HWIC-1FE is a true L3 interface and is expensive. It has feature parity with an onboard FE interface except for OAM support, which is delayed.
HWIC-4ESW has the capability to setup VLAN but they are not the routed ports Whereas, HWIC-1FE has the same characteristics as Onboard FE ports.
