WAN throughput on a 2801

Unanswered Question
Apr 2nd, 2009

Can someon confirm this? I have been informed that the total WAN throughput on a 2801 is 1.5 Mbps no matter if the connection is coming through the ethernet port, a serial port or whatever? I thought it was much higher than that.

Thanks in advance! All replies rated!

I have this problem too.

BTW, Jon quoted performance for a 2811.

The 2801 is a little slower at about 46 Mbps for CEF.

Also keep in mind, you often need to allow for duplex traffic, i.e. 46 Mbps would be 23 Mbps for duplex.

Further, you want to avoid running the router at 100%, so you might want to divide the perforamance in half or more.

I.e., 2801 might well "safely" handle about 10 Mbps (duplex).

PS:

NB: There are other differences between the 2800 models. A visible one is module slots. Not so visible, might be subtle ones, such as 2801 doesn't (I believe) support Etherchannel across its ports, but the other 2800 series models do.

Don't listen to that person anymore :-). I've attached a performance guide that shows what each router can do. You will notice if you process switch it is 1.5Mbps, but you should run CEF unless you have a specific reason.

Hope that helps.

Thanks guys. They person that informed us of that was in Cisco Pre-sales! Maybe he was trying to bump us up a notch
