We have two admin nodes and two PSNs.
There is a network switch. When one of the laptops connected to a port on the switch authenticates via PSN1, it is successfully authenticated. However, when it sends the authentication request to PSN2, then on ISE authentication logs, I see network device not found. Why is one of the PSN recognizing the switch, while the other PSN is not? Both the PSNs are in sync with admin node.
