Hello,
We are using ISE for radius authentication. I have setup a new Cisco switch stack at one of our locations and setup the network device in ISE. Unfortunately, when trying to authenticate, the ISE logs show a failure of "Could not locate Network Device or AAA Client" The reason for this failure is the log shows it's coming from the wrong IP address. The IP address of the switch is 10.xxx.aaa.241, but the logs show it is 10.xxx.aaa.243. I have removed and re-added the radius configs on both ISE and the switch, but it still comes in as .243. There is another switch stack at that location (same model, IOS etc), that works properly.
The radius config on the switch:
aaa new-model
!
!
aaa authentication login default local
aaa authentication login Comm group radius local
aaa authentication enable default enable
aaa authorization exec default group radius if-authenticated
ip radius source-interface Vlanyy
radius server 10.xxx.yyy.zzz
address ipv4 10.xxx.yyy.zzz auth-port 1812 acct-port 1813
key 7 abcdefg
The log from ISE:

As a test, I setup a device using the .243 address. While ISE claims it authenticates, it really doesn't. I have to use my local account to access the device.
Any advice on how to resolve this issue would be appreciated. Please let me know if more information is needed.
