Meaning behind RCB and MWAR in Wireless Terminology?

Hi Folks,

sorry if that is kind of a beginners question,
but I have been working with Cisco Wireless for quiet some while without it being my main focus.

But I stuble a lot across the shortcuts RCB and MWAR.
And I couldn't find out what those two abbreviations mean by searching the Web.

From what I understand when I see the two terms:
I have to issue "show capwap client rcb" on APs to see the info to which WLC the AP is joined.
And it refers to the WLC as mwar then.

So MWAR seems to be a term for the WLC,
and RCB a term which holds this kind of information.

Is this correct?
And if yes or no, what do the two terms mean anyway? 🙂

Thanks a lot in advance and best regards!

RCB is radio control block, don’t know what mwar stands for.

MWAR reference controller info like name, ip, etc. That is all I know:)

MWAR is an acronym for Main Wireless Application Routine. This goes way back to the old days before Cisco acquired Airespace.
