I am new to IPS applications and was wondering if there was any difference in the IPS software I have installed on my 1841 router vs the IPS software on a 3825 router I am looking into purchasing. On the 1841 I am using the IOS c1841-advsecurityk9-mz.124-21.bin and on the 3825 c3825-advsecurityk9-mz.124-3j.bin
The functionality of the IPS software and the signature selection is the same between those two platforms. But IPS processing takes a toll on both CPU and memory. The 3825 will have more of these resources available and could handle a larger amount of traffic as a result.
