Thanks Reza, the customer is disappointed as ISE was installed nearly a year ago for device profiling initially, yet we haven't got that far because the platform requires 802.1x on the interfaces configured to send AAA for profiling information. I think stacked 2960x run warmer and higher CPU like the 3750s. I'm thinking of moving them to IBNS v2.0.

High CPU with 2960x Stacks and 802.1x configuration. I have a customer with stacks of 2960-x switches which have high CPU once .1x configuration is applied on the interfaces. Process such as Auth Manger and CPU - EPM ACL PLUG-IN are very high. Had a Cisco TAC case open for a couple of months now, it has gone to the Architecture team, they suspected memory leak, we keep sending outputs but so far no answer.

Hello, have you tried updating your device drivers?
I would suggest next step is packet capture, get an over the air capture?
You our can also get a capture from the AP, I don’t have the commands to hand but I would check to see what is occurring.
also take local capture on laptop and check it’s arp table for local gateway during issue.

Seeing this on AireOS 8.5.120.0 with Cisco 2802 APs.
Windows 7 Device shows limited connectivity, the ARP entry is gone for the gateway.
The WLC shows client in run state and fully associated and authenticated.
Can see Client is continually broadcasting FF:FF:FF:FF:FF:FF on the air, to resolve, client needs to disconnect/reconnect or wait for EAP re-key to resume access and for limited conncectivity to disappear.
Issue does not occur at set time, same AP will still be serving other clients.

The DVDs and Drive were okay, there were in fact booting, however the DVD menu was only shown on monitor output (despite the read me guide stating it would display on both serial and video).

Hi Marce1000,
Yes, I used Nero Burning Tools and verified.
The DVD boots using a number of servers and I see the Prime Infrastructure menu/install screen, but not on the Prime Appliance.
Additionally, I have burnt working disks for the old ISE Appliance which appears to be similar model of IBM x3550.

Hello, I have a Generation 1 Appliance that I am trying to install/upgrade to Prime Infrastructure 3.1 (3.1.4 supports Gen 1).
The appliance will not boot from DVD, we do not even get to the Prime Menu option boot screen.
According to the read me this should appear automatically after server initialization.
I have tried Prime Infrastructure 3.0 and 3.1 Dual Layer DVDs and explicitly telling the server to boot from DVD.
I have also tried a different DVD Drive.
The DVDs are high quality, and confirmed working on other servers.
Has anyone encountered this issue on PRIME-NCS-APL-K9 appliance? Almost like the server bios/firmware needs updating.

Hi George, could you let me know what you have in your 'Wireless Essentials Kit' for troubleshooting Cisco Wireless Networks.
Site Survey Tool - i.e. Airmagnet (which you use)/Ekahau Spectrum Analysis - i.e. Airmagnet Spectrum/ Chanalyzer Packet Capture (On the go) - i.e. AirPcap+EyePA
Anything else you recommend?

I have the answer to my question: Please refer to the following link which mentioned that we can’t use any other versions than openssl 0.9.8, since the controller will not accept the certificate, please check the following links which mentioned that: http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/109597-csr-chained-certificates-wlc-00.html#conf https://supportforums.cisco.com/document/102151/certificate-signing-requests-wlc-open-ssl

Hey, So according to the Cisco Security Advisory the WLC is listed as non vulnerable - So the WLC HTTPs WebGUI cert does not internally use OpenSSL or at least a vulnerable version. What about those who are using a Captive Portal for Guest Wireless? Many people use OpenSSL to convert 3rd Party certificates for the Portal as per the Cisco guides?
