Cisco & DFS Channels

[Alucidnation]

Why is it that Cisco do not support 5G channels 120,124, & 128 in the UK?

These channels are legal for use in this country, albeit if they are enabled there should be a 10 minute wait for them to become active.

I'm reasonably sure other enterprise manufacturers support them.

Cisco does support those channels in the UK, you just need to enable the Extended UNII-2 channels checkbox. See the screenshot.

Hi Martin,

Extended channels enabled and I have tried to select channel 116 to use in an 80Mhz config for ac clients but it comes back telling me it is not available to use in the country, (as 120,124 &128 make up the 'channel').

I have been in contact with support and they had a look at my settings etc and have told me the same!

After a bit of investigation, it turns out that these channels must have DFS, but would have a 10 minute wait.

Currently running wlc os 8.1.131.0

Unless i am missing something?
