Rate Limiting on Cisco Router

Thu Jul 8 22:28:02 UTC 2010

That's strange, Are you paying for a CIR of 80Mb/s? 
Normally they only leave the limiting up to you if its more of a
burstable connection, Like you pay for 80Mb/s but its a full line rate
interface and its billed per Mb/s over 80 on a 95th percentile scheme.
If that is the case you can safely go over 80Mb/s for a certian amount
of time per month, Assuming its billed monthly.

Subject: Rate Limiting on Cisco Router

Thanks again for all the responses to my previous post.

We have a Cisco 7206VXR router with IOS of 12.4(12) and a PA-POS-1OC3
card ofr our OC3.

The problem we have now is that we are only paying for 80 MB/s of the
OC-3, and the ISP is leaving the capping of it up to us. I have
googled and the only things I can find is that you can not do a real
cap on this type of interface.

We have tried the rate-limit command with various parameters and we
are unable to keep it at 80. I have read that this is not the correct
way to do it, but I'm not sure what is.

Any advice?

Pointers appreciated.
