We are using ISE 3.4 P4 on Essentials license. We have a CWA Self Registered portal that is supposed to assign static identity group on registration. No profiling is involved.We are observing problems where endpoints are not being assigned to the sta...

I am trying to use the Genie API get_boot_variables(). It has a model specific function for cat3k, but the API is not detecting cat3k devices from my testbed file. I am guessing it uses the testbed.devices.device.type field. Does anyone have an expla...

Interesting bug. It is listed as an open caveat on latest 9800 and 8500 code. Workaround is to disable OFDMA but supposedly just affects MS Teams? I'm suspicious it's a bigger problem than documented.https://bst.cloudapps.cisco.com/bugsearch/bug/CSCw...

I performed an OTA capture and noticed a lot of the traffic I was interested in had frame size ~3KB. It is all UDP. Could this be problematic with MSS of 1.5KB? Particularly when channel utilization gets high?

I am sending CDP attributes to ISE during endpoint authentication. I am struggling to use these attributes in an authorization policy. I want a policy that matches if cdpCachePlatform contains 'Phone'. So far, the policy does not match.This is the po...

Hello, I have discovered the answer. The platform field in device testbed must match one of the Unicorn supported platforms.https://pubhub.devnetcloud.com/media/unicon/docs/user_guide/supported_platforms.html

I have been troubleshooting a similar problem with Microsoft HoloLens and ~10 clients per AP. I’m curious about technical explanation for the provided workaround since it would disable ax capability.

I'm working with a developer that has a real time bi-directional video application. We have Cisco 9120 APs configured for 40Mhz channels. We observe 70-80% channel utilization when ~8 clients are on the same AP. The app begins to experience jitter as...

Thanks. I am wondering about the frame size. I believe it will get fragmented as the traffic is routed which could be bad for UDP performance? High channel utilization is not good for any traffic but I’m guessing larger frames are more susceptible to...

This thread is still relevant and this setting should be better documented. These are the wmm-default values on 9800 WLC which is default global setting. They look very wrong.
