7204VXR support for 10GE?

Unanswered Question

We've got a 7204VXR router with an NPE-400 and a 1-port gigabit ethernet card, connecting to our upstream provider. We are looking into moving to a new provider on a 10 gigabit ethernet link, keeping the original connection as a backup.

Can the 7204VXR support 10 gig ethernet? Is there enough capacity to support 10 gig ethernet and the original 1 gig ethernet?

Nope and nope.

 

For 10g, you'll want to look at the ASR 1k series.

 

PS:

Actually a NPE-400 is undersized for gig.  Wire-speed gig Ethernet, for minimum size packets, needs a PPS rate of 1.488 Mpps.  For duplex, double that.  So even a NPE-G2 can be undersized for gig.  Of course, most traffic isn't minimal size packets and often you're not pushing full link capacity, so wire-speed capable performance isn't always required.

Thanks for the information... there is also a 3560G that will probably need to be replaced. We'd need one with 3-4 10gb ports. What's the best option?

I'm with Joseph. 

 

You want to push 10 Gbps then you are potentially looking at an ASR 1004 with RP2 and ESP40.

 

Describe the 3560 you want to replace.  What's the role?  Is this a distribution or a core switch?  If this is so, then I'd be looking at a 4500X.

The "latest" in the 3560 series would be the 3560X but it only support two 10 ports.  However the even newer 3650 supports four 10g ports.
