check delay to release,delay to CoA ,delay to renew setting
delay to release time should be low since it needs to occur immediately after the applet is downloaded and before the Cisco ISE server directs the NAD to re-authenticate with a CoA request. The default release value is 1 second.
the delay to CoA delays the Cisco ISE from executing the CoA. Here, enough time should be given to allow the applet to download and perform the IP release on the client. The default value is 8 seconds.
The delay to renew value is added to the IP release value and does not begin timing until the control is downloaded. The renew should be given enough time so that the CoA is allowed to process and the new VLAN access granted. The default value is 12 seconds.
Check the "Enable Agent IP refresh after VLAN change" parameter to refresh the Windows client IP address in both wired and wireless environments for MAB with posture.
To ensure the Mac OS X client IP address is refreshed when the assigned VLAN changes, this parameter is required for Mac OS X client machines accessing the network via the native Mac OS X supplicant in both wired and wireless environments.
Note When you use the "Enable Agent IP refresh after VLAN change" option, Cisco ISE sends "DHCP release delay" and "DHCP renew delay" settings (as specified below) instead of using the "Network transition delay" setting used for Windows Agent profiles. If you do not use the "Enable Agent IP refresh after VLAN change" option, Cisco ISE sends "Network transition delay" timer settings to client machines, but Cisco ISE will not send both.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
