Disabling CFS Distribution on a Switch Chapter 13 Using the CFS Infrastructure Send documentation comments to [email protected] CFS Distribution Modes CFS supports different distribution modes to support different application requirements: coordinated and uncoordinated distributions. Both modes are mutually exclusive. Only one mode is allowed at any given time. Uncoordinated Distribution Uncoordinated distributions are used to distribute information that is not expected to conflict with that from a peer. An example is local device registrations such as iSNS. Parallel uncoordinated distributions are allowed for an application. Coordinated Distribution Coordinated distributions can have only one application distribution at a given time. CFS uses locks to enforce this. A coordinated distribution is not allowed to start if locks are taken for the application anywhere in the fabric. A coordinated distribution consists of three stages: 1. A fabric lock is acquired. 2. The configuration is distributed and committed. 3. The fabric lock is released. Coordinated distribution has two variants: • CFS driven -The stages are executed by CFS in response to an application request without intervention from the application. • Application driven-The stages are under the complete control of the application. Coordinated distributions are used to distribute information that can be manipulated and distributed from multiple switches, for example, the port security configuration. Unrestricted Uncoordinated Distributions Unrestricted uncoordinated distributions allow multiple parallel distributions in the fabric in the presence of an existing coordinated distribution. Unrestricted uncoordinated distributions are allowed to run in parallel with all other types of distributions. Disabling CFS Distribution on a Switch By default, CFS distribution is enabled. Applications can distribute data and configuration information to all CFS-capable switches in the fabric where the applications exist. This is the normal mode of operation. You can globally disable CFS on a switch, to isolate the applications using CFS from fabric-wide distributions while maintaining physical connectivity. When CFS is globally disabled on a switch, CFS operations are restricted to the switch and all CFS commands continue to function as if the switch were physically isolated. To globally disable or enable CFS distribution on a switch using Fabric Manager, follow these steps: Step 1 In the Physical Attributes pane, expand Switches > CFS. 13-4 Cisco MDS 9000 Family Fabric Manager Configuration Guide OL-17256-03, Cisco MDS NX-OS Release 4.x

Chapter 13

Using the CFS Infrastructure

Disabling CFS Distribution on a Switch

CFS Distribution Modes

CFS supports different distribution modes to support different application requirements: coordinated and

uncoordinated distributions. Both modes are mutually exclusive. Only one mode is allowed at any given

time.

Uncoordinated Distribution

Uncoordinated distributions are used to distribute information that is not expected to conflict with that

from a peer. An example is local device registrations such as iSNS. Parallel uncoordinated distributions

are allowed for an application.

Coordinated Distribution

Coordinated distributions can have only one application distribution at a given time. CFS uses locks to

enforce this. A coordinated distribution is not allowed to start if locks are taken for the application

anywhere in the fabric. A coordinated distribution consists of three stages:

A fabric lock is acquired.

The configuration is distributed and committed.

The fabric lock is released.

Coordinated distribution has two variants:

•

CFS driven —The stages are executed by CFS in response to an application request without

intervention from the application.

•

Application driven—The stages are under the complete control of the application.

Coordinated distributions are used to distribute information that can be manipulated and distributed

from multiple switches, for example, the port security configuration.

Unrestricted Uncoordinated Distributions

Unrestricted uncoordinated distributions allow multiple parallel distributions in the fabric in the

presence of an existing coordinated distribution. Unrestricted uncoordinated distributions are allowed to

run in parallel with all other types of distributions.

Disabling CFS Distribution on a Switch

By default, CFS distribution is enabled. Applications can distribute data and configuration information

to all CFS-capable switches in the fabric where the applications exist. This is the normal mode of

operation.

You can globally disable CFS on a switch, to isolate the applications using CFS from fabric-wide

distributions while maintaining physical connectivity. When CFS is globally disabled on a switch, CFS

operations are restricted to the switch and all CFS commands continue to function as if the switch were

physically isolated.

To globally disable or enable CFS distribution on a switch using Fabric Manager, follow these steps:

Step 1

In the Physical Attributes pane, expand

Switches > CFS
