Configuring Fabric Binding

About Fabric Binding Activation and Deactivation

The fabric binding feature maintains a configuration database (config database) and an active database. The
config database is a read-write database that collects the configurations you perform. These configurations
are only enforced upon activation. This activation overwrites the active database with the contents of the
config database. The active database is read-only and is the database that checks each switch that attempts to
log in.
By default, the fabric binding feature is not activated. You cannot activate the fabric binding database on the
switch if entries existing in the config database conflict with the current state of the fabric. For example, one
of the already logged in switches may be denied login by the config database. You can choose to forcefully
override these situations.
After activation, any already logged in switch that violates the current active database will be logged out,
Note
and all switches that were previously denied login because of fabric binding restrictions are reinitialized.
