MAPS upgrade and downgrade considerations

When downgrading from Fabric OS 7.2 to any previous version of the OS, the following

MAPS-related behaviors should be expected:

• When an active CP is running Fabric OS 7.2 with MAPS disabled, and the standby device has

an earlier version of the Fabric OS, High Availability will be synchronized, but MAPS will not be

allowed to be enabled until the firmware on the standby device is upgraded. The

mapsConfig --enablemaps command fails and an error message is displayed.

• When an active CP is running Fabric OS 7.2 and MAPS is enabled, but the standby device is

running Fabric OS 7.1 or earlier, then High Availability will not be synchronized until the standby

CP is upgraded to Fabric OS 7.2.

• On devices with a single CP, there is no change in behavior when downgrading to an earlier

version of the Fabric OS.

• When a configuration download occurs, the MAPS configuration is downloaded onto a switch

only if MAPS is enabled on that local switch.

Migrating from Fabric Watch to MAPS

To use MAPS, you must migrate from Fabric Watch to MAPS. On a switch running Fabric OS 7.2.0 or

later, or when you upgrade your existing switch to Fabric OS 7.2.0, Fabric Watch is enabled by

default. On an upgraded switch, Fabric Watch continues to monitor as in Fabric OS 7.1.0 until

MAPS is activated.

When you migrate from Fabric Watch to MAPS, the Fabric Watch configuration can be converted to

a MAPS-compatible configuration so you do not need to reconfigure all of the thresholds and rules.

If you do not make the conversion as part of the migration, you will need to configure the rules

manually.

Activating MAPS is a chassis-specific process, and you can activate only one chassis at a time. On a

given chassis there can be multiple logical switches. Activating MAPS will enable it for all logical

switches in the chassis. Each logical switch can have its own MAPS configuration.

To migrate from Fabric Watch and activate MAPS, run the following commands:

mapsconfig --enablemaps

followed by

mapsconfig --fwconvert -enablepolicy policyname

Upon successful completion of this command, the following happens:

• Fabric Watch configurations are converted to MAPS policies. Refer to “Fabric Watch legacy

policies” on page 23 for additional information.

To not convert the Fabric Watch configurations when you activate MAPS, do not include

--fwconvert in the command.

• Fabric Watch monitoring and commands are disabled.

• MAPS commands are enabled.

• The MAPS policy that is specified in the -enablepolicy policy parameter is enabled.
