Enhanced 911 Support
ArubaOS provides seamless support for emergency calls in the Dell network by interoperating with RedSky
emergency call server. The controller uses SNMP to interoperate with RedSky call handling system.
You must configure the Red Sky server as an SNMP host and enable SNMP traps to activate the E911 feature on
the controller. For more information on configuring the RedSky server as SNMP host, see “Configuring SNMP”
on page585.
The E911 support has the following basic functions:
 Location tracking
 Call handling
 Caller identification and callback capability
For information on call-handling, caller identification and callback capability, see the RedSky documentation.
The controller tracks the location of the voice clients and notifies the emergency call server using SNMP traps.
The controller notifies the location of a voice client to the emergency server:
 When it identifies a voice client
 When a voice client roams from one access point to another access point in the same controller
 When a voice client roams from one access point to another access point in a different controller
 When a voice client registers with a PBX system
The notification process ensures that the emergency call server is notified whenever a voice client is identified or
the location of the client is updated. If a voice client roams outside of a WLAN coverage, the controller does not
send any notifications to the emergency call handling system. This may happen when there is a sudden loss of
WLAN coverage due to extreme conditions such as, fire accidents. In such cases, the last associated access point
will be the location of the voice client.
The emergency call server queries the controller using the SNMP 'get' request to get the location of a specific
emergency caller. In response to the location query, the controller sends the following parameters to the
emergency server:
 Client IP Address
 Client Mac Address
 AP Name
 AP Wired MAC
NOTE: This release of ArubaOS supports only RedSky emergency call server.
NOTE: The controller tracks the location only for voice clients. To track the location of a remote voice client, the administrator
must configure the location of the remote access point in the controller or emergency call server.
