Facing one issue for the new switch installed and trying to authenticated vty access through acs 22.214.171.124 version.
On switch configuration below
debug logs says this and i could see that there is no response coming from acs server and seems acs is having some issue.let me know if you see any issue on the switch side configuration. same configuration ,same model and IOS for other switch is working fine .switch rebooted and aaa new model was reconfigured already.appreciate inputs about if anybody faced the similar issue .I am suspecting issue on the acs side and thought to reboot it however need to know if anybody exp. this kind of behavior earlier.
The things is ACS is still showing aaa unknown client although configured in the device and aaa client in network device group!
Pls find more details below of switch and acs logs. PS:no issues with port 49 to telnet from switch and readability with source interface basics checks are already done .
