Enabling Fabric Binding

The fabric binding feature must be enabled in each switch in the fabric that participate in the fabric
binding. By default, this feature is disabled in all switches in the Cisco MDS 9000 Family.
The configuration and verification commands for the fabric binding feature are only available when
fabric binding is enabled on a switch. When you disable this configuration, all related configurations are
automatically discarded.

Configuring a List of sWWNs

A user-specified fabric binding list contains a list of switch WWNs (sWWNs) within a fabric. If a
sWWN attempts to join the fabric, and that sWWN is not in the list or the sWWN is using a domain ID
that differs from the one specified in the allowed list, the ISL between the switch and the fabric is
automatically isolated in that VSAN and the switch is denied entry into the fabric.
The persistent domain ID must be specified along with the sWWN. Domain ID authorization is required
in FICON VSANs where the domains are statically configured and the end devices reject a domain ID
change in all switches in the fabric.

Activating Fabric Binding

The fabric binding maintains a configuration database (config-database) and an active database. The
config-database is a read-write database which 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 login.
By default, the fabric binding feature is not activated. You cannot activate 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 the force option to override these situations.
After activation, any already logged in switch that violates the current active database will be logged
out, and all switches that were previously denied login due to fabric binding restrictions will be
reinitialized.

Forcing Fabric Binding Activation

If the database activation is rejected due to one or more conflicts listed in the previous section, you may
decide to proceed with the activation by using the force option.
