Controller Based WLANs

How to move the controlpath/datapath pcap file to internal flash of an Aruba Controller?
Requirement:

An Aruba Controller running 6.4.4.x and above.



Solution:
In many situations we may need to enable packet captures on an Aruba Controller to investigate the network related issues, in some situations we would not be able to setup a external device to store the captures so we can copy the pcap files to the internal flash of Aruba Controller temporarily for testing purposes and delete it after the debugging.


Configuration:
We can configure to the pacp files to Aruba Controller flash and below is an example of sending a controlpath capture files to the flash.
 
(ArubaMaster) #
(ArubaMaster) #packet-capture controlpath udp all
(ArubaMaster) #packet-capture copy-to-flash controlpath-pcap
(ArubaMaster) #
(ArubaMaster) #
(ArubaMaster) #show packet-capture

Active Capture Destination
--------------------------
Destination    Disabled

Active Capture (Controlpath)
----------------------------
Interprocess   Disabled
Sysmsg         Disabled
TCP            Disabled
UDP            Enabled    Ports: All
Other          Disabled

Active Capture (Datapath)
-------------------------
Wifi-Client    Disabled
Ipsec          Disabled

(ArubaMaster) #

 



Verification

We can see the capture file has been sent to the flash as below.

(ArubaMaster) #dir
