I need to find the CPU clock-speed of an ISR.
show version does not indicate this information on the c2811 I have running on an SP services IOS image.
Couldn't even locate this on 2800 series feature comparison given in,
Thanks in advance for your time.
The performance metric is compared by router models not CPU. It's not like you can purchase a router and have the option to upgrade the CPU for faster performance.
The performance metric by router models is explained on the document I pointed out.
What more information do you want than the one provided by the PDF?
