FIGURE 13 Starting point for QoS
Upgrade and downgrade considerations for Adaptive Networking in AG mode
The Brocade G620 is supported in Fabric OS v8.0.0 and subsequent releases. Downgrading to a prior release is not supported.
Upgrading to Fabric OS v7.1.0 from Fabric OS v6.4.0 is supported. Note the following considerations when upgrading to Fabric OS
v7.1.0 from Fabric OS v6.2.X and earlier and downgrading from Fabric OS v7.1.0 to Fabric OS v6.2.X and earlier:
∙ If any of the AG QoS-enabled ports are active and you attempt a firmware downgrade, the downgrade is prevented. You must
disable the QoS-enabled ports before performing a firmware downgrade.
∙ Upgrades from earlier versions to Fabric OS v7.1.0 are allowed, but AG QoS-enabled ports do not become effective until the
ports are disabled or enabled so that QoS mode can be negotiated on the ISLs.
Adaptive Networking on Access Gateway considerations
∙ QoS is configured in the fabric, as normal, and not on the AG device.
∙ QoS on Access Gateway is only supported on Fabric OS 6.3 and later.
∙ You should disable HBA QoS if connecting to an AG device running Fabric OS 6.2 or prior release.
∙ Disable QoS on an AG port if it connects with a switch running Fabric OS 6.2. Otherwise, the port will automatically disable with
an error. To recover, disable QoS on the port, and then enable the port.
