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.
Figure 14-43. Compression Statistics page
The Compression Statistics page contains the following options/fields:
Selection Entry Description
Queue01…08 [RO] Displays statistics in a table format showing:
Pre-Header Comp Bytes
Post-Header Comp Bytes
Header Comp % Savings
Pre-Payload Comp Bytes
Post-Payload Comp Bytes
Payload Compression Ratio
DefQue
Global All traffic that does not fall within a defined QoS Rule is indicated in the
‘Global’ (Default Rule Queue).
CLEAR C Allows a reset of the Statistics of a specific Queue.
ClrAll A Resets all Compression Statistics.
ClrDefQ D
Base [1] B View up to 8 different Queues per screen. To allow editing on any of the 32
definable entries, select a base address to control which 8 QoS Queues are
displayed.
For example, if you want to view QoS Queues 16-24, then a Base value of
16 should be defined.
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.
