Introduction
This document explains how to interpret the output displayed by the show compress command when hardware compression is enabled (that is, when you implement compression in the Compression Service Adapter [CSA] hardware).
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on these software and hardware versions:

The show compress Command
In order to see what the show compress command does, view this sample output:
Router#show compress Serial6/1 Hardware compression enabled CSA in slot3 in use Compressed bytes sent: 402 bytes 0 Kbits/sec ratio: 4.092 Compressed bytes recv: 390 bytes 0 Kbits/sec ratio: 3.476 restarts:1 last clearing of counters: 1278 seconds
Field Definitions
The information displayed here by the show compress command is the same for both hardware and distributed compression. For Cisco 7200 Series Routers with multiple CSAs, an additional line is displayed to indicate the CSA currently in use.

|
Compressed bytes sent |
Total number of compressed bytes sent including the kilobits per second |
|
Compressed bytes recv |
Total number of compressed bytes received including the kilobits per second |
|
ratio |
Compression ratio for bytes sent and received since the link last came up or since the counters were last cleared. |
|
restarts |
