Fabric Binding Enforcement
Fabric Binding
Requires activation on a per VSAN basis.
Allows specific user-defined switches that are allowed
to connect to the fabric, regardless of the physical
port to which the peer switch is connected.
Does not learn about switches that are logging in.
Cannot be distributed by CFS and must be configured
manually on each switch in the fabric.
Port-level checking for xE ports is as follows:
• The switch login uses both port security binding and fabric binding for a given VSAN.
• Binding checks are performed on the port VSAN as follows:
While port security complements fabric binding, they are independent features and can be enabled or disabled
separately.
Fabric Binding Enforcement
To enforce fabric binding, configure the switch world wide name (sWWN) to specify the xE port connection
for each switch. Enforcement of fabric binding policies are done on every activation and when the port tries
to come up. For a Fibre Channel VSAN, the fabric binding feature requires all sWWNs connected to a switch
to be part of the fabric binding active database.
Configuring Fabric Binding
The fabric binding feature ensures ISLs are only enabled between specified switches in the fabric binding
configuration. Fabric binding is configured on a per-VSAN basis.
Configuring Fabric Binding
To configure fabric binding in each switch in the fabric, perform this task:

◦ TE port security binding check on each allowed VSAN
Port Security
to a Fibre Channel device (a host or another switch),
also identified by a WWN. By binding these two
devices, you lock these two ports into a group (or
list).
Requires activation on a per VSAN basis.
Allows specific user-defined physical ports to which
another device can connect.
Learns about switches or devices that are logging in
if learning mode is enabled.
Can be distributed by CFS.
