   3  * Routines for the disassembly of packets sent from Cisco WLAN
   4  * Controllers, possibly other Cisco access points, and possibly
   5  * other devices such as Aruba access points.  See

   9  * which speaks of Aruba access points supporting remote capture and
  10  * defaulting to port 5000 for this, and also speaks of Cisco access
  11  * points supporting remote capture without any reference to a port
  12  * number.  The two types of remote capture are described separately;
  13  * there's no indication of whether they use the same protocol for
  14  * streaming packets but perhaps other protocols for, for example,
  15  * discovery and setup, or whether they use different protocols
  16  * for streaming packets.
  17  *

  22  * speaks of Aruba and Cisco access points together, mentioning port 5000.
  23  *
  24  * Apparently Aruba supports several protocols, including Peek remote.
  25  * See the packet-aruba-erm dissector.
  26  *
  27  * Tested with frames captured from a Cisco WCS.
