additional 10/100 interface for cisco 1720 router

Hi there
I have a cisco 1720 router with 1 fastethernet (builtin) and 1 serial port.
I'd like to attach an additional fast ethernet card / port to it.
which model number would I need?

Scotty_cisco

you have a 1720 I am assuming you have an unused wic slot opposite the other t1 card right?

The one I would use is this.

WIC-4ESW

it is a 4 port switch.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123relnt/1700/rn1700xc.htm

but it is not Fastethernet and it looks like it is only supported in the 1721

WIC-1ENET
http://www.cisco.com/en/US/products/hw/routers/ps221/products_tech_note09186a008009483a.shtml

is supported but again is not a fastethernet

Thanks

Cisco EtherSwitch HWIC - switch - 4 ports

Product ID
Mfg. Part: HWIC-4ESW-POE
UNSPSC: 43222612

I think that is the part you are looking for. I emailed my sales rep to confirm. This is a four port switch. I added one like this to our router and created vlans and assigned each interface to separate vlans and each port acts a separate router interface.

Sorry, wrong card. Scotty-Cisco is correct with WIC-4ESW. Mine was for power over ethernet.

But, each port can be placed in a separate vlan and assigned an IP address and will act as a separate interface. It is easier that using sub-interfaces on routers.

According to my sales rep, it is compatible with the 1720.

I agree with Scotty_Cisco that you should dble-chk with your vendor about their return policy. But, my CDWG pre-sales Cisco Enginneer swears that it works.
