show logging profile wireless filter mac <rClient_MAC> to-file always-on-<FILENAME.txt>
RadioActive Tracing:
debug wireless mac <Client_MAC>
Embedded Captures filtered by client MAC:
monitor capture MYCAP clear
monitor capture MYCAP interface Po1 both
monitor capture MYCAP buffer size 100
monitor capture MYCAP match any
monitor capture MYCAP inner mac <Client_MAC>
monitor capture MYCAP start
!!Reproduce
monitor capture MYCAP stop
monitor capture MYCAP export flash:|tftp:|http:.../filename.pcap
show wireless stats client summary | i <Client_MAC>
