RRM DCA algorithm and DCA sensitivity

jsmbrown · ‎12-10-2008

Can anyone explain in detail the way DCA works? I have read the RRM document - http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008072c759.shtml#dca_algorithm

many times and I still do not understand DCA fully. It would help to have examples as well as to know when DCA sensitivity setting of high would be recommended.

Thanks,

Joe

DCA Sensitivity Level The configured DCA sensitivity setting: low, medium, or high. This setting determines how sensitive the DCA algorithm is to environmental changes such as signal, load, noise, and interference when determining whether to change channels.You can use the config advanced {802.11a | 802.11b} channel dca sensitivity {low | medium | high} CLI command to configure the DCA sensitivity level.
