I am not sure what you are asking...
These are instructions I followed for WLAN packet capture
Aruba Instant version 6.1.2.3-2.0.0.3 and above have the pcap command to do the wireless packet capture on the IAP. This command is not exposed on the Web UI and has to run from the CLI.
1. Enable Telnet option to the IAP. By default Telnet or terminal access is disabled.
2. Use "show ap monitor status" to identify the base BSSID.
WLAN Interface

bssid scan monitor probe-type phy-type task channel pkts
----- ---- ------- ---------- -------- ---- ------- ----
'''00:24:6c:ae:81:68''' enable enable m-portal 80211a-HT-40 tuned 149+ 360116135
'''00:24:6c:ae:81:60''' enable enable sap 80211b/g-HT-20 tuned 11 172543704
In the example above, the base bssid for 80211a is "00:24:6c:ae:81:68" and "00:24:6c:ae:81:60"
3. Use "pcap start <base bssid> <ip address of PC with Aruba version of Wireshark installed> <port> 0 1518"
Example:
pcap start 00:24:6c:ae:81:68 10.163.148.35 5555 0 1518
4. Use "show pcap" to check the active pcap session

5. Use "pcap stop <base bssid> <pcap-id> to stop the capture
Example:
pcap stop 00:24:6c:ae:81:68 1
6. Run the Aruba version of Wireshark on the PC, on the capture interface, select ARUBA udp-port=5555
