Domain-Id - HP 5920 Series Command Reference Manual

Usage guidelines
This command takes effect only when the fabric configuration function is enabled.
A fabric reconfiguration triggers a principal switch selection phase.
A fabric reconfiguration can be disruptive or nondisruptive.
A fabric reconfiguration can be disruptive or nondisruptive.
Disruptive reconfiguration—Floods 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, and 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.
For fabric settings that do not take effect immediately (for example, switch priority), you can perform a
disruptive reconfiguration to make them take effect.
