We recommend that you disable compression in the router's main processor if the router CPU load exceeds 40 percent. To display the CPU load, use the show process cpu EXEC command. This section documents new or modified commands. All other commands used with this feature are documented in the Cisco IOS Release 11.2 command references. To disable compression, use the no form of this command.
Compression is implemented in the software installed in the router's main processor.
For all platforms except Cisco 7200 series and platforms that support the VIP2, compression is implemented in the software installed in the router's main processor. This option applies only to Cisco 7200 series routers. Default Compression is disabled. 11.2 P and 11.1 CA to include the distributed , software , and csa keywords. Using CSA hardware compression on Cisco 7000 series routers with RSP7000, Cisco 7200 series routers, and Cisco 7500 series routers removes the compression and decompression responsibilities from the VIP2 or the main processor installed in the router.
