We have ISE 2.4 Patch 5 running with distributed environment (7 PSNs, 1 Admin & 1 MnT)
We are using Cisco 2960+ switches with IOS 15.2(4)SE6 with all access ports in closed mode.
For Desktops & Laptops we are using 802.1x auth method using AnyConnect 4.6.362 and for rest of the endpoints we are using MAB auth method.
Now, here is an issue.
We get calls from users that suddenly they are not getting network connectivity and everything was fine some time back.
While troubleshoot we observe in logs that there pc/laptop was successfully authenticated via 802.1x and now requests are suddenly coming via MAB (despite having anyconnect present and services running)
Post reboot 2 or 3 or multiple times issue resolves.
We are unable to understand what causes this behaviour when things are going normal. This happens across all Windows OS (7/10, 32/64 bit)
Request you to share your suggetions and experience.
