disabled. If the strict SCC and DCC fabric-wide consistency policies match, the corresponding SCC and
DCC ACL policies are compared.
The enforcement of fabric-wide consistency policy involves comparison of only the Active policy set.If the
ACL polices match, the switch joins the fabric successfully. If the ACL policies are absent either on the
switch or on the fabric, the switch joins the fabric successfully, and the ACL policies are copied
automatically from where they are present to where they are absent. The Active policy set where it is
present overwrites the Active and Defined policy set where it is absent. If the ACL policies do not match, the
switch cannot join the fabric and the neighboring E_ports will be disabled.
Use the
fddcfg –fabwideset
command on either this switch or the fabric to set a matching strict SCC
or DCC fabric-wide consistency policy. Use ACL policy commands to delete the conflicting ACL policy from
one side to resolve ACL policy conflict. If neither the fabric nor the joining switch is configured with a
fabric-wide consistency policy, there are no ACL merge checks required.
The descriptions above also applies to joining two fabrics. In this context, the joining switch in the above
descriptions becomes a joining fabric.
NOTE:
The existing SCC policy in the adjacent or joining switch are enforced before the fabric-wide
consistency policy is applied.
The next sections describe the interaction between the databases with active SCC and DCC policies and
combinations of fabric-wide consistency policy settings when fabrics are merged.
Matching fabric-wide consistency policies
For example: Fabric A with SCC:S;DCC (strict SCC and tolerant DCC) joins Fabric B with SCC:S;DCC
(strict SCC and tolerant DCC), the fabrics can merge as long as the SCC policies match (both are strict).
Table 31
describes the impact of merging fabrics with the same fabric-wide consistency policy that have
SCC and/or DCC policies.

To resolve the policy conflict, manually distribute the database you want to use to the switch with
the mismatched database. Until the conflict is resolved commands such as fddcfg --fabwideset and
