CISCO-ZS-EXT-MIB

        The MIB module for the management of zoning within 
the framework of Cisco's Zoning Server (ZS) Archi-
tecture which realizes the FC-GS4/SW3 requirements 
for Zone Server. This MIB is an extension to the
CISCO-ZS-MIB, which is for managing zoning
conforming to FC-GS3/SW2. The FC-GS4 specification
is Fibre-Channel - Generic Services - 4 T11/
Project 1505-D/Rev 7.8. The SW3 specification is
Fibre-Channel - Switch Fabric - 3 T11/Project 1508-
D/Rev 6.6.
        
GS4/SW3 allows zoning to operate in either basic
or enhanced mode of operation. Basic mode is
essentially GS3/SW2 compatible mode (as modelled
by CISCO-ZS-MIB). Enhanced mode of operation
provides additional capabilities. In enhanced mode
of operation, all the configuration should be
done within the scope of a session. 
        
The current 'Running Configuration' on the local device
for zone server is called the 'effective' database.
When the first configuration command on the zone server
data is received, a snapshot of the current 'effective 
database' is taken on the local device. This 
snapshot is called the 'copy' database. An implicit
session is started by the Zone Server on the local 
device and all subsequent SET operations take place
in the context of this session. The 'copy' database
is used for all further modifications in the
session. There can be only one session active in the
entire Fibre Channel fabric. The user who initiates
the creation of this 'copy', is called the owner of
session. When a session has been created on a device
in the Fibre Channel fabric, if an attempt is made
to start a session from any other device in the 
fabric, it results in error.
        
Once the modifications to the 'copy' are done, a 
'commit' operation can be done. The 'commit' done
on the local device, results in the local 'effective
database' being overwritten with the 'copy' and
then the new local 'effective database' is
distributed to all other devices in the Fibre Channel
fabric. The successful 'commit' operation also results
in destroying the 'copy' on the local device. The
'commit' can only be performed by the owner of the
session. 
        
The 'copy' can optionally be destroyed without any
distribution. This can be done by performing a
'clear' operation.
