AAA / Adding additional ACS server

anuragvadakkekara — Mon, 11 Mar 2019 04:06:21 GMT

Hello Guys,

Need to setup AAA proposed plan as attached.We have been using current setup since very long for both our office devices and data centre devices.Now we wanna to add one more ACS apart from the existing two and need to point out all the data centre devices to this new ACS server.

Is it possible to configure multiple groups for multiple devices and seperate ACS server's for defined groups ? If possible please let me know the commands and if not, please let me know the alternate ways.

Hope you could understand my requirements and current setup. PFA..

Many Thanks in advance !!

Best Regards,

Anurag.K

Hi Anurag,

You can add the new ACS/tacacs server and have that server in top of the sequence.

tacacs server host 10.16.2.10

tacacs server host 10.16.2.8

tacacs server host 10.16.2.9

tacacs server key xxxxx

If you really want to create a seperate group for the new ACS/tacacs server then you need to have below listed configuration.

aaa group server tacacs+ GROUP1

server 10.16.2.8

server 10.16.2.9

aaa group server tacacs+ GROUP2

server 10.16.2.10

aaa authentication login default group GROUP1 GROUP2 line

Let me knoiw if you have any doubts.

AAA / Adding additional ACS server

anuragvadakkekara — Sun, 17 Nov 2013 07:03:08 GMT

Thanks for your detailed revert mate!!!

However i have one more concern regarding with accounting.If i authenticate data centre devices with ACS 3 (newly added), from where i can get the accounting details. Would it be in the same server or can i accessible from the other ACS servers (1 & 2) as well ?

If accounting information only accessible from ACS server 3 for data centrre devices, is there any way to access the same from ACS 1 & 2 ? If yes, please share the relevant configurations for the same.

Many Thanks in adavance ..

Best Regards,
