Cisco 7921 - Spectrum management is not enabled/supported by AP.

Hi all :)

I get the following alarm from the site survey on a 7921.

Spectrum management is not enabled/supported by AP.

Can anyone tell me what this means?

Also, when you are walking around doing a site survey, what is the CU?

Many thx indeed,

Ken

This is referring to 802.11h when using 5 GHz.

I assume this is the Cisco Unified Wireless LAN Controller?

If so, check to ensure that Channel Announcement and Channel Quiet Mode are enabled

See page 44 in the 7921G Deployment Guide @ http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7921g/6_0/english/deployment/guide/7921dply.pdf')">http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7921g/6_0/english/deployment/guide/7921dply.pdf.

CU stands for Channel Utilization, which is based on QBSS information provided by the AP to inform the client how busy the channel is.

What's the model of your AP and the WLC's firmware?
