Hi, I'm new to Cisco h/w and have been self training on reconfiguring a 1721 router with a 1DSU T1 WIC. The router was originally for our internet connection. The left slot has the above WIC the right slot is empty. What I want to do is simply use the router to connect to a seperate network within our facility. My question is, do I need to use a different WIC card and if so, what should I use? THanks.
Then the WIC-1ENET should work just fine! Tn IOS you will see a new ethernet interface which you would need to configure and connect to the other site.
Hi, you only need to connect a a switch that does vlans and configure vlan encap on the fastethernet interfface.
Alternatively you need WIC-1E.
Both solution will allow hosts on the two segments to communicate but NOT at wire-speed,
thing for which you should get a L3 switch, the smaller of these is WS3560-8PC.
Hope this helps, please rate post if it does!
