I have a Cisco 1720; as you may know, it has just one Fast Ethernet port, but two WIC slots where I can add additional interfaces.
I would like to add a second Fast Ethernet port. However, I don't know if Cisco have ever produced a Fast Ethernet WIC that is compatible with the 1700 series.
A dual Fast Ethernet WIC would be ideal, a single Fast Ethernet WIC would be suitable. All I can see though is a 10 Mb Ethernet WIC (WIC-1ENET). Alternatively, would I be able to use the ports on a WIC-4ESW as separate Fast Ethernet interfaces (which I could assign IP addresses to)?
