FCS policies

FCS policy distribution
The FCS policy can be automatically distributed using the fddCfg -- fabwideset command or it can
be manually distributed to the switches using the distribute -p command. Each switch that receives
the FCS policy must be configured to receive the policy. To configure the switch to accept
distribution of the FCS policy, refer to
“Database distribution settings” on page 225.
Database distributions may be initiated from only the Primary FCS switch. FCS policy configuration
and management is performed using the command line or a manageability interface.
Only the Primary FCS switch is allowed to distribute the database. The FCS policy can be manually
distributed across the fabric using the distribute -p command. Since this policy is distributed
manually, the command fddCfg
–-
fabwideset is used to distribute a fabric-wide consistency policy
for FCS policy in an environment consisting of only Fabric OS v6.2.0 and later switches.
FCS enforcement for the distribute command is handled differently for FCS and other databases in
an FCS fabric:
•
For an FCS database, the enforcement allows any switch to initiate the distribution. This is to
support FCS policy creation specifying a remote switch as Primary.
•
For other database distributions, only the Primary FCS switch can initiate the distribution.
The FCS policy distribution is allowed to be distributed from a switch in the FCS list. However, if
none of the FCS switches in the existing FCS list are reachable, receiving switches accept
distribution from any switch in the fabric. To learn more about how to distribute policies, refer to
“ACL policy distribution to other switches” on page 227.
Local switch configuration parameters are needed to control whether a switch accepts or rejects
distributions of FCS policy and whether the switch is allowed to initiate distribution of an FCS policy.
A configuration parameter controls whether the distribution of the policy is accepted or rejected on
the local switch. Setting the configuration parameter to accept indicates distribution of the policy
will be accepted and distribution may be initiated using the distribute -p
command. Setting the
configuration parameter to reject indicates the policy distribution is rejected and the switch may
not distribute the policy.
The default value for the distribution configuration parameter is accept, which means the switch
accepts all database distributions and is able to initiate a distribute operation for all databases.

Distribution policy states
Fabric OS State
v6.2.0 and later configured to accept Target switch accepts distribution and fabric state change occurs.
v6.2.0 and later configured to reject Target switch explicitly rejects the distribution and the operation fails.
The entire transaction is aborted and no fabric state change occurs.
