Hello all,
Our devices are configured to point to 3 ACS servers using the following commands:
aaa new-model
aaa group server tacacs+ ACS
server x.x.x.x
server x.x.x.x
server x.x.x.x
exit
On a recent IOS deployment all of the 'server x.x.x.x' commands were removed from the config following a reboot. This was on a wide range of devices using 122 40, also tried 122-44 with the same affect. Can anyone explain why?
Thanks in advance.

HI Paul, [Pls Rate if HELPS]
Possible reasons are:
1. The Configuration was not saved before reload [write memeory (or) copy running-config start-up config]
2. The router could have got loaded with the start-up config [ie., the running-config & start-up config may not be same]
3. If there are any Config that are saved as Archives [in flash] means, may be that could have loaded by some means of command that are put in config before reload.
Hope I am Informative.
Pls RATE if HELPS

Hi, all configs were definitely saved before the reload. All of the other AAA configuration remained, just the list of servers disappeared.

HI Paul, [Pls Rate all INFORMATIVE POST]
Normally during the IOS change process, the "no aaa new-model" is executed to avoid the un-necessary authentication Issue during the work.
Is there any such executed ?
Is there any Logs thrown on the Console during the Reload Process ?
If any capture please POST
Hope I am Informative.
Pls RATE all Informative POST

HI Paul, [Pls Rate all informative POST]
Not sure on what's happening. Need to check the IOS version support for the ACS.
If you re-configure the Server IP @ Address whether the Commands are accepted ?
Best Regards,
