Chapter 46 Configuring Fabric Binding
Configuring Fabric Binding
Verify the status of the fabric binding feature of a fabric binding-enabled switch by entering the show
fabric-binding status command:
switch# show fabric-binding status
VSAN 1:Activated database
VSAN 4:No Active database
About Switch WWN Lists
A user-specified fabric binding list contains a list of switch WWNs (sWWNs) within a fabric. If an
sWWN attempts to join the fabric, and that sWWN is not on 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.
Configuring Switch WWN List
To configure a list of sWWNs and optional domain IDs for a Fibre Channel VSAN, perform this task:
This example configures the sWWN of another switch to the configured database list for domain ID 3:
switch(config)# fabric-binding database vsan 10
switch(config-fabric-binding)# swwn 21:00:05:30:23:1a:11:03 domain 3
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.
Command Purpose
Step 1
switch# configuration terminal
switch(config)#
Enters configuration mode.
Step 2
switch(config)# fabric-binding database vsan
vsan-id
switch(config-fabric-binding)#
Enters the fabric binding submode for the
specified VSAN.
switch(config)# no fabric-binding database vsan
vsan-id
Deletes the fabric binding database for the
specified VSAN.
Step 3
switch(config-fabric-binding)# swwn swwn-id
domain domain-id
Adds the sWWN of another switch for a
specific domain ID to the configured
database list.
switch(config-fabric-binding)# no swwn swwn-id
domain domain-id
Deletes the sWWN and domain ID of a
switch from the configured database list.
