Switch WWN List Configuration

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.
To configure a list of sWWNs and domain IDs, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fabric-binding database vsan 5
switch(config-fabric-binding)#
switch(config)# no fabric-binding database vsan
10
Step 3
switch(config-fabric-binding)# swwn
21:00:05:30:23:11:11:11 domain 102
Step 4
switch(config-fabric-binding)# swwn
21:00:05:30:23:1a:11:03 domain 101
Step 5
switch(config-fabric-binding)# no swwn
21:00:15:30:23:1a:11:03 domain 101
Step 6
switch(config-fabric-binding)# exit
switch(config)#

Fabric Binding Activation

The fabric binding 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 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.
