Hi All,

Just a quick question, i have a 2911 as stated above which come with a base IOS of: c2900-universalk9-mz.SPA.152-4.M2.bin

I have downgraded the image to: c2900-universalk9-mz.SPA.150-1.M7.bin, however when the router initially boots i receive:

csdb tcp synwait-time 30

^

% Invalid input detected at '^' marker.

csdb tcp idle-time 3600

csdb tcp finwait-time 5

Is this something to do with the image i have downgraded to?

The errors you are seeing suggest that there are commands in your startup config that are not supported in the version of IOS you are using. This is to be expected if you go from a newer to an older version of IOS. It may or may not effect the functionality of your setup - it depends what you are trying to do...
