Configuring fabric reconfiguration
IMPORTANT:
The fabric reconfiguration feature takes effects only when the fabric configuration feature is enabled.
A fabric reconfiguration can be performed manually or automatically by using the automatic
reconfiguration feature.
A fabric reconfiguration triggers a principal switch selection phase.
A fabric reconfiguration can be disruptive or nondisruptive.
• Disruptive reconfiguration—Floods the Reconfigure Fabric (RCF) frames throughout the fabric, and
notifies all switches to perform a disruptive reconfiguration. During the reconfiguration procedure,
each switch clears all data and performs renegotiation. Data transmission in the fabric is disrupted.
• Nondisruptive reconfiguration—Floods Build Fabric (BF) frames throughout the fabric, and notifies
all switches to perform a nondisruptive reconfiguration. During the reconfiguration procedure, each
switch tries to save the last running data for its domain ID to remain unchanged. Thus, data
transmission in the fabric is not disrupted.
You can manually perform a disruptive reconfiguration after an interface is isolated or the priority of a
switch is modified in a fabric.
A disruptive reconfiguration is automatically performed if the domain ID lists overlap when two fabrics
are merged.
A nondisruptive reconfiguration is automatically performed when one of the following conditions exists:
• When two fabrics are merged, the principal switch information of the two fabrics is different, and
the domain ID lists are not empty and do not overlap.
