I have a Cisco 9800 WLC where i am experiencing Teams call dropout issue while connecting to the Guest SSID.This is an intermittent issue. Have tried debugging the client MAC but didn't noticed any issue in that.
Can some one please help me to know where to look at for RF related message in the logs?
Let's analyze what you have stated "Citrix is working well on wired and on other SSID's except for guest"
Thanks for the information, i may ask you anotehr question.....is this worked before and was stable guest network ? or is this new setup having issue ?
as suggested other poster, you need to look the config and path to reach internet or other network resource you looking to access.
This is one of the most difficult issues to troubleshoot in the enterprise. My approach to this kind of issues will be to follow the below generic guidelines while I mostly end up with troubleshooting mostly from the client side and I use point 4 & 5 to maximum advatange.
From Client side
1. Make sure that the client wireless drivers are latest.
2. Make sure MSTeams application is updated and latest.
3. Make sure that the client is connected on 5GHz.
4. Use a resource monitor to Check the PC utilization (Memory, Storage, CPU) randomly when MSTeams to make sure client has enough resources.
5. Install an agent such as thousandeyes to get more visibility and information out of the client.
6. Use MTR test to MSTeams public IP's to check if there is any bottleneck inside your network.
From Wireless side
1. Make sure that the RF utilization on the channel AP's are in are within acceptable limits.
2. Use band select to steer clients to 5GHz and use latest Cisco recommended codes.
3. Use thousandeyes agents in wired infra and compare the outputs with the agent installed in the enpoint
4. Use NBAR based QOS and translate the same in to the wired infra as well.
5. Deploy correct RF profiles based on the environment (channel width, channel selection, ap location, antenna gain etc)
Microsoft recommendations related to MSTeams;
Best way to check is that you need to have a Spectrum Analyzer like Ekahu sidekick.
You can also use Cisco spectrum expert if you have AP's with RF ASIC (Cat 9000 series) as this will allow you to read the spectrum while AP is serving clients.
From WLC you can get an overview of channel utilization from AP prospective
show ap dot11 5ghz load-info
show ap dot11 24ghz load-info
show ap config slots
show ap name <APName> auto-rf dot11 24ghz
show ap name <APName> auto-rf dot11 5ghz
As @Scott Fella mentioned we need more visibility in to your issue to help you out. On top of what Scott already mentioned you need to give us like What WLC model, code, AP model, ap mode, client type, driver version etc.
