Verifying CFS Distribution Status

The show cfs status command displays the status of CFS distribution on the switch.
switch# show cfs status
Fabric distribution Enabled

CFS Application Requirements

All switches in the fabric must be CFS capable. A Cisco MDS 9000 Family switch is CFS capable if it
is running Cisco SAN-OS Release 2.0(1b) or later. Switches that are not CFS capable do not receive
distributions and result in part of the fabric not receiving the intended distribution.
CFS has the following requirements:
•
•
•
•

Enabling CFS for an Application

All CFS based applications provide an option to enable or disable the distribution capabilities. Features
that existed prior to Cisco SAN-OS Release 2.0(1b) have the distribution capability disabled by default
and must have distribution capabilities enabled explicitly.
Applications introduced in Cisco SAN-OS Release 2.0(1b) or later have the distribution enabled by
default.
The application configuration is not distributed by CFS unless distribution is explicitly enabled for that
application.

Verifying Application Registration Status

The show cfs application command displays the applications that are currently registered with CFS. The
first column displays the application name. The second column indicates whether the application is
enabled or disabled for distribution (

Implicit CFS usage—The first time you issue a CFS task for a CFS-enabled application, the
configuration modification process begins and the application locks the fabric.
Pending database—The pending database is a temporary buffer to hold uncommitted information.
The uncommitted changes are not applied immediately to ensure that the database is synchronized
with the database in the other switches in the fabric. When you commit the changes, the pending
database overwrites the configuration database (also known as the active database or the effective
database).
CFS distribution enabled or disabled on a per-application basis—The default (enable or disable) for
CFS distribution state differs between applications. If CFS distribution is disabled for an
application, then that application does not distribute any configuration nor does it accept a
distribution from other switches in the fabric.
Explicit CFS commit—Most applications require an explicit commit operation to copy the changes
in the temporary buffer to the application database, to distribute the new database to the fabric, and
to release the fabric lock. The changes in the temporary buffer are not applied if you do not perform
the commit operation.
