Parameter Description
"triggered", the Randomization Interval is not used and is set to
0. A Randomization Interval of 0 in a measurement request indic-
ates that no random delay is to be used. This field can be given a
value in the range (0, 65535). The default value is 0.
Measurement Duration This value is used to set the Measurement Duration field in the
Transmit Stream/Category Measurement Request frame. The
Measurement Duration is set to the duration of the requested
measurement. It is expressed in units of TUs. When the request
mode for the Transmit Stream/Category Measurement Request
frame is set to triggered, the Measurement Duration field
should be set to 0. This field can be given a value in the range (0,
65535). The default value is 9776.
Traffic ID The value is used to set the Traffic Identifier field in the Transmit
Stream/Category Measurement Request frame. The Traffic Iden-
tifier field contains the TID subfield. The TID subfield indicates
the TC or TS for which traffic is to be measured. This field can be
given a value in the range (0, 255). The default value is 96
Bin 0 Range This value is used to set the 'Bin 0 Range' field in the Transmit
Stream/Category Measurement Request frame. Bin 0 Range
indicates the delay range of the first bin (Bin 0) of the Transmit
Delay Histogram, expressed in units of TUs. This field can be
given a value in the range (0, 255). The default value is 6.
In the CLI
To select the information to be sent in TSM report requests using the command-line interface, access the CLIin
config mode and issue the following command.

BSSTransition Management (802.11v)
BSS Transition Management enables an AP to request a voice client to transition to a specific AP, or suggest a
set of preferred APs to a voice client, due to network load balancing or BSS termination. This helps the voice
client identify the best AP to which that client should transition to as that client roams. ArubaOS supports BSS
Transition Management features defined by the 802.11v standard.
The BSS Transition capability can improve throughput, data rates and QoS for the voice clients in a network by
shifting (via transition) the individual voice traffic loads to more appropriate points of association within the
ESS.
Frame Types
BSS Transition Management uses the following frame types:
l Query: A Query frame is sent by the voice client that supports BSS transition management requesting a
BSS transition candidate list to its associated AP, if the associated AP indicates that it supports the BSS
transition capability.
