SCC Policies
The switch connection control (SCC) policy is used to restrict which switches can join the fabric.
Switches are checked against the policy each time an E_Port-to-E_Port connection is made. The
policy is named SCC_POLICY and accepts members listed as WWNs, domain IDs, or switch names.
Only one SCC policy can be created.
By default, any switch is allowed to join the fabric; the SCC policy does not exist until it is created.
When connecting a Fibre Channel router to a fabric or switch that has an active SCC policy, the
front domain of the Fibre Channel router must be included in the SCC policy.
SCC policy states are shown in Table 32.
Virtual Fabric considerations: In a logical fabric environment the SCC policy enforcement is not
done on the logical ISL. For a logical ISL-based switch, the SCC policy enforcement is considered as
the reference and the logical ISL is formed if the SCC enforcement passes on the extended ISL. The
following changes:
• A logical switch supports an SCC policy. You can configure and distribute an SCC policy on a
logical switch.
• SCC enforcement is performed on a ISL based on the SCC policy present on the logical switch.
For more information on Virtual Fabrics, refer to Chapter 10, “Managing Virtual Fabrics”.
