I am reconfiguring an IAP-105 I picked up for use with surveying to use for a one off event coming up in a few weeks and I thought the process was fairly straightforward to configure a static channel on an IAP, basically just the configuration:
arm
a-channels 165
The intent that arm would have only channel 165 to pick from and thus never stray from 165. In practice, this configuration has the IAP start up on channel 44 and never go to 165. Additionally if I add in other channels (but removing channel 44):
arm
a-channels 36,40,48,52,56,60,64,100,165
it ignores them as well. Running an rf-summary shows:
Survey IAP-105# show ap arm rf-summary

I was able to override arm via the 'a-channel 165 18' command but I clearly missed something in the arm setup. Can someone give me a hint as to where I went wrong? Thanks!
