[AFMUG] What is Stuck VC, and is there anything I can do about it?

2014-09-29 Thread Bill Prince via Af 
Customer's SM went off line for almost two hours, and my only clue 
(besides it appearing off line from my end too) was this in the log file 
on the SM:


   09/26/2014 : 09:50:06 PDT : :Timezone set to PDT
   09/28/2014 : 13:44:26 PDT : :Stuck VC cleared (VC38)
   09/28/2014 : 13:48:24 PDT : :XO trim at min diff=-1498 c=7 cmove=-9
   f=7785 fmove=-148

 This is a PMP450 (5 GHz) on firmware 12.2.2.

Used to be an issue in 900 mhz sms i actually helped discover ; a stuck VC was 
a stuck virtual channel that would cause an SM to remain offline until the SM 
was rebooted.  They added code in at some point to check for that and clear 
the stuck vc so the SM didn't have to be rebooted anymore.  In our case, i 
think, it was control slot related (or at least increasing the control slots 
helped to slow the problem down until they added code to check for it).

I'm sure someone from Cambium can give you a more technical explanation :)
