cisco 3925 looking for Gig ethernet card recommendation

tonnesen · ‎10-16-2013

I am looking to add 2 Gig ethernet ports into one of the card slots of the cisco 3900 router. I was given the following two part numbers and these look like serial ports NM-1T3/E3 or Vwic3-2MFT T1/E1. Comments please

Exactly what are you trying to do? What are these "2 Gig ethernet ports" going to be connected to?

they will be used for connecting to other networks

The above will provide two routed gog ports, although on any 3900, the router doesn't have the performance to guarantee even one gig port at wire-speed.
