Hello,
I am implementing ISE 2.4 patch 1 with Posture Services in Huawei S5700 switches and I am seeing this behavior. After posture process, ISE send Disconnect Request to Huawei switch and endpoint reauthenticate and begins a new posture process. This behavior remains continuously in a looping process.
As workaround, I unchecked CoA Push RFC 5176 in Network Device Profile. After this, ISE send "CoA Request" to Huawei switch instead "Disconnect Request".
Best Regards,
Daniel Stefani
