Since their upgrade to ISE 2.1 they have experienced some of their PSNs going into an inconsistent state which shows up as either a slow login for their users or being thrown into Internet only. A simple reboot of the PSN appears to correct everything.</P><P></P><P>The customer is asking the following questions:</P><UL><LI>Should they be rebooting the PSN on a regular schedule? <UL><LI>Their thoughts were to do 1/3 of the PSN every month so each quarter each PSN would be rebooted at least once.</LI></UL></LI><LI>Is there a best practice around rebooting PSN?<UL><LI>Or should I steer them towards restarting the service</LI></UL></LI><LI>Are we seeing this in other accounts?</LI><LI>Regardless if this is recommended or not… is there a way to automate the reboot of the PSN?</LI></UL></BODY></HTML> Fri, 30 Sep 2016 06:07:00 GMT https://community.cisco.com/t5/network-access-control/ise-psn-reboot-questions/m-p/3521340#M537398 Marc Poretti 2016-09-30T06:07:00Z Re: ISE PSN Reboot Questions https://community.cisco.com/t5/network-access-control/ise-psn-reboot-questions/m-p/3521341#M537408 <HTML><HEAD></HEAD><BODY><P>Marc,</P><P></P><P>This is not expected behavior.&nbsp; I recommend the customer open up a TAC case so that the deployment can be examined to determine why a reboot is necessary.</P><P></P><P>Regards,</P><P>-Tim</P></BODY></HTML> Mon, 03 Oct 2016 17:39:37 GMT https://community.cisco.com/t5/network-access-control/ise-psn-reboot-questions/m-p/3521341#M537408 Timothy Abbott 2016-10-03T17:39:37Z Re: ISE PSN Reboot Questions https://community.cisco.com/t5/network-access-control/ise-psn-reboot-questions/m-p/3521342#M537415 <HTML><HEAD></HEAD><BODY><P>Thanks Tim,</P><P></P><P>I anticipated your response. thanks for confirming.</P><P></P><P>On a side (but similar) note, are you aware of any way to automate the reboot of the PSN?
