ip-compression

To enable compression on the FCIP link, use the ip-compression command in interface configuration

submode. To disable compression, use the no form of the command.

Syntax Description

Command Modes

Interface configuration submode.

Command History

Usage Guidelines

When no compression mode is entered in the command, the default is auto.

The FCIP compression feature introduced in Cisco SAN-OS Release 1.3 allows IP packets to be

compressed on the FCIP link if this feature is enabled on that link. By default the FCIP compression is

disabled. When enabled, the software defaults to using the auto mode (if a mode is not specified).

Cisco SAN-OS Release 2.0(1b) and later, you to configure FCIP compression using one of the following

OL-8413-07, Cisco MDS SAN-OS Release 3.x

ip-compression [auto | mode1 | mode2 | mode3]

no ip-compression [auto | mode1 | mode2 | mode3]

Enables automatic compression setting.

Enables fast compression for the following high bandwidth links:

— IPS-4 and IPS-8, less then 100 Mbps

— MPS-14/2, up to 1 Gbps

Enables moderate compression for medium bandwidth links less then 25

Enables compression for bandwidth links less then 10 Mbps.

Modification

This command was introduced.

Changed the keywords from high-throughput and high-comp-ratio to

mode1, mode2, and mode3.

mode1 is a fast compression mode for high bandwidth links (> 25 Mbps)

mode2 is a moderate compression mode for moderately low bandwidth links (between 10 and 25

mode3 is a high compression mode for low bandwidth links (< 10 Mbps)

auto (default) mode picks the appropriate compression scheme based on the bandwidth of the link

(the bandwidth of the link configured in the FCIP profile's TCP parameters)
