Interopmode - Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Command Reference Manual

interopMode

Enables or disables Brocade switch interoperability with McDATA switches.
Synopsis interopmode [mode [-z McDataDefaultZone] [-s McDataSafeZone]]
Description Use this command to enable or disable Brocade switch interoperability with McDATA switches
within a Brocade fabric.
Fabric OS v6.0.0 introduced a McDATA Enterprise OS (M-EOS)-compatible McDATA Open Fabric
Mode (interopMode 3) on all platforms that support McDATA Fabric Mode (interopMode 2). Open
Fabric Mode is intended specifically for adding Fabric OS-based products into M-EOS fabrics that
are already using McDATA Open Fabric Mode. Fabrics comprised of only Fabric OS switches in
McDATA Open Fabric Mode are not supported and cannot be zoned. All zoning of a mixed M-EOS
and Fabric OS fabric operating in McDATA Open Fabric Mode is performed through the M-EOS
switches.
Notes Interop Mode 1 (former "open" mode) is not supported in Fabric OS v6.0.0 or later.
The interopMode command must be executed on all Brocade switches in the fabric. The following
restrictions apply when changing Fabric modes:
•
•
•
When changing From Brocade Native to McDATA Fabric or McDATA Open Fabric Mode:
•
•
When changing from McDATA Fabric or McDATA Open Fabric Mode to Brocade Native Mode:
•
When changing between McDATA Fabric mode and McDATA Open Fabric mode:

Fabric OS Command Reference
53-1001186-01
Switches must be disabled (offline) when changing Fabric mode. Changes to take effect after
the switch reboots automatically.
Not all services are available in interop mode. Refer to the Fabric OS Administrator's Guide for
details.
Zone commands in McDATA Open Fabric Mode (3) are disabled except display commands and
two set commands, cfgDisable and cfgClear, which can only be called when the switch is
offline.
McDATA Fabric mode only supports a user domain ID range of 1-31, which is added to the
domain offset to get the PID domain range. The domain range for McDATA Open Fabric mode is
97 to 127. The existing preferred configuration must be changed to a value within this range
before the conversion is allowed. If your domain is out of range, the system makes a best
estimate of what the domain should be. For example, if your domain is 0x92, going to McDATA
Fabric mode (2) will end up at domain 2 (mask out upper bits). Or, when changing to McDATA
Open Fabric Mode (3), your domain will end up at 0x62 (98 decimal). Mask out upper bits, and
add a domain offset of 0x60.
Existing zone configurations, defined and effective, will be erased. The switch assumes the
zone configuration from the fabric it joins or a new configuration must be configured.
Existing zone configurations, defined and effective, are erased. The switch assumes the zone
configuration from the fabric it joins or you must create a new configuration.
The system reboots and the configuration is lost.
