Cisco MDS 9000 Family Fabric Manager Configuration Guide

Chapter 48 Configuring FCIP
Default Settings
Table 48-5 lists the performance settings for different cards.
Note 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.
Caution 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.
Tip 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.
Default Settings
Table 48-6 lists the default settings for FCIP parameters.
