| Description | The configured Domain_ID of the particular switch on this
Fabric, or zero if no Domain_ID has been configured.
The meaning of this object depends on
t11FamConfigDomainIdType object.
If t11FamConfigDomainIdType is 'preferred', then the
configured Domain_ID is called the 'preferred Domain_ID'.
Valid values are between 0 and 239. In a situation where
this Domain_ID cannot be assigned, any other Domain_ID
will be acceptable. A value of zero means any Domain_ID.
If t11FamConfigDomainIdType is 'insistent', then the
configured Domain_ID is called the 'insistent Domain_ID' and
valid values are between 1 and 239. In a situation where
this Domain_ID cannot be assigned, no other Domain_ID is
acceptable.
In both of the above cases, the switch sends an RDI (Request
Domain_ID) to request this Domain_ID to the Principal
Switch. If no Domain_ID is able to be granted in the case
of 'preferred', or if an 'insistent' Domain_ID is configured
but not able to be granted, then it is an error condition.
When this error occurs, the switch will continue as if it
receives a SW_RJT with a reason/explanation of 'Unable to
perform command request'/'Domain_ID not available'. That
is, its E_Ports on that Fabric will be isolated and the
administrator informed via a 't11FamDomainIdNotAssigned'
notification.
If t11FamConfigDomainIdType is 'static', then the configured
Domain_ID is called the 'static Domain_ID' and valid values
are between 1 and 239. In this situation, there is no
Principal Switch in the Fabric and the Domain_ID is simply
assigned by configuration, together with the Fabric_Name.
A switch configured with a static Domain_ID, on receiving
an EFP, BF, RCF, DIA, or RDI SW_ILS, shall reply with an
SW_RJT having Reason Code Explanation 'E_Port is Isolated'
and shall isolate the receiving E_Port.
