14.2.11.2.5 Compression Statistics

Activate the Compression Statistics page from the Statistics Menu page. This page displays
counts of the number of bytes before and after for both Header and Payload Compression. For
Header Compression, the percentage of bandwidth savings is displayed. For Payload
Compression, the effective compression ratio is displayed.
The Compression Statistics page contains the following options/fields:
Selection
Queue01...08
DefQue
Global
CLEAR
ClrAll
ClrDefQ
Base [1]
Note: Although the QoS option is not required to use Header or Payload Compression, the
Compression Statistics are displayed by QoS Rule flow Queues. If QoS is not enabled, all the
Compression Statistics will fall within the Global Queue.
