FCIP Compression

The FCIP compression feature 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).

The "auto" mode (default) selects the appropriate compression scheme based on the card type and

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

With SAN-OS 3.3(1) and later NX-OS, all compression options (auto, mode1, mode2, mode3) mean

hardware deflate on 9222i and MSM 18+4. There is no software compression.

The Cisco MDS 9216i and 9222i Switches also supports the IP compression feature. The integrated

supervisor module has the same hardware components that are available in the MPS-14/2 module.

The compression modes in Cisco SAN-OS Release 2.0(1b) and later and NX-OS are incompatible with

the compression modes in Cisco SAN-OS Release 1.3(1) and earlier.

While upgrading from Cisco SAN-OS Release 1.x to Cisco SAN-OS Release 2.0(1b) or later and

NX-OS, we recommend that you disable compression before the upgrade procedure, and then enable the

required mode after the upgrade procedure.

If both ends of the FCIP link are running Cisco SAN-OS Release 2.0(1b) or later and NX-OS and you

enable compression at one end of the FCIP tunnel, be sure to enable it at the other end of the link.
