Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

Procedure
Step 1
Enable the fabric configuration feature.
Step 2
Configure a list of sWWNs and their corresponding domain IDs for devices that are allowed to access the
fabric.
Step 3
Activate the fabric binding database.
Step 4
Copy the fabric binding active database to the fabric binding configuration database.
Step 5
Save the fabric binding configuration.
Step 6
Verify the fabric binding configuration.
Enabling Fabric Binding
The fabric binding feature must be enabled in each switch in the fabric that participates in the fabric binding.
By default, this feature is disabled in Cisco Nexus 5000 Series switches. 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.
To enable fabric binding on any participating switch, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Enables fabric binding on that switch.switch(config)# fabric-binding enable
Step 2
Disables (default) fabric binding on that
switch.
switch(config)# no fabric-binding enable
Step 3
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:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
