Firmware upgrade and downgrade considerations for MAPS
The following firmware upgrade and downgrade considerations apply to the Monitoring and Alerting
Policy Suite (MAPS) in this version of Fabric OS.
Firmware upgrade considerations
When upgrading to Fabric OS 7.4.0, there are four main scenarios:
• Upgrading if Fabric Watch is installed but not enabled (activated) before the upgrade to Fabric OS
7.4.0.
• Upgrading if Fabric Watch is installed and enabled before the upgrade to Fabric OS 7.4.0.
• Upgrading if MAPS was installed before the upgrade to Fabric OS 7.4.0, but not enabled.
• Upgrading if MAPS was installed before the upgrade to Fabric OS 7.4.0, and is enabled.
Each of these scenarios is discussed in the following sections. In addition, MAPS Fabric Performance
Impact monitoring and the legacy bottleneck monitoring feature are mutually exclusive. If the legacy
bottleneck monitoring feature was enabled before the upgrade, MAPS will not monitor fabric
performance.
Upgrading if Fabric Watch is installed but not enabled
If Fabric Watch is installed on the switch but is not enabled at the time of the upgrade, then MAPS is
installed and will monitor the fabric using the policy named “dflt_base_policy” which has the basic
monitoring capabilities and will not permit you to migrate any custom Fabric Watch thresholds as part of
the upgrade.
NOTE
If the Fabric Vision license is not active before you upgrade, then you cannot enable any policies and
MAPS will monitor the fabric using only the basic monitoring capabilities until the Fabric Vision
license is installed.
Upgrading if Fabric Watch was installed and is enabled
If Fabric Watch is installed on the switch and is enabled, then MAPS is installed with the basic
monitoring capabilities, you can migrate any existing Fabric Watch thresholds as part of the change to
MAPS.
