I´m currently looking for a document that specify how many MAC addresses can be stored and authenticated via an ACS (1120)? I prefer to use the internal identity store over AD or LDAP for MAB authentication for 802.1X project.
I would like to know what is the impact on the ACS? CPU/MEM?
What is the impact on the user authentication? delay, timeout, etc.
Please specify any other restriction or side effect.
Thanks for your input
If you have one Standalone server you cannot disable the ACS Log Collector features on it. Usually the best approach is to get another ACS 5.x registered as a Secondary Instance of the Primary ACS.
The Primary ACS will handle the Authentication Load and we can change the Log Collector to run on the Secondary ACS server instead.
With the above deployment the Primary ACS will only perform authentication tasks while the secondary will be used for authentication if the primary goes down. The Secondary will always run as the Log Collector reducing the load on the Primary ACS.
Hope this helps
