Cisco ASA Hardware Resource Question for Netflow and Traffic Policing
Posted on 2014-02-12
I would like to leverage and extract more value out of our Cisco ASA. Specifically with regards to bandwidth management and network monitoring.
I would like to enable Netflow exporting on the ASA to a "Netflow Trap" as well as traffic policing or shaping, the latter of which uses the ASA's RAM for buffering.
Currently our ASA has 256 RAM and can be maxed out at 512MB. Of the 256 we are using 150MB. Also, CPU usage is very low, around 15%.
My question is, if I turn on Netflow as well as some form of simple traffic policing or shaping, how much RAM do you think will be used up by doing so? Just wonder if anyone has had experience with doing these particular things.
thanks for the help.
