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 are incompatible with the
Caution
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, we
Tip
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 you enable
compression at one end of the FCIP tunnel, be sure to enable it at the other end of the link.
