The Active policies set where they are present overwrite the Active and Defined policies set where they are absent. If the ACL policies do not match, the switch can join the fabric, but an error message flags the mismatch. Under both conflicting conditions, secPolicyActivate is blocked in the merged fabric. Use fddcfg -fabwideset command to resolve the fabric-wide consistency policy conflicts. Use the distribute command to explicitly resolve conflicting ACL policies. When a switch is joined to a fabric with a strict SCC or DCC fabric-wide consistency policy, the joining switch must have a matching fabric-wide consistency policy.

The following examples show how to set a strict SCC and tolerant DCC fabric-wide consistency policy.
Notes on joining a switch to the fabric
When a switch is joined to a fabric with a tolerant SCC or DCC fabric-wide consistency policy, the joining
switch must have a matching tolerant SCC or DCC fabric-wide consistency policy. If the tolerant SCC or
DCC fabric-wide consistency policies do not match, the switch can join the fabric, but an error message
flags the mismatch. If the tolerant 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 policies match, the switch joins the fabric successfully. If the ACL policies are absent 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 side to where they are absent. The Active policies set where they are present
overwrite the Active and Defined policies set where they are absent. If the ACL policies do not match, the
switch can join the fabric, but an error message flags the mismatch.
Under both conflicting conditions,
secPolicyActivate
is blocked in the merged fabric. Use
fddcfg
–fabwideset
command to resolve the fabric-wide consistency policy conflicts. Use the
distribute
command to explicitly resolve conflicting ACL policies.
When a switch is joined to a fabric with a strict SCC or DCC fabric-wide consistency policy, the joining
switch must have a matching fabric-wide consistency policy. If the strict SCC or DCC fabric-wide
consistency policies do not match, the switch cannot join the fabric and the neighboring E_ports will be
