Managing the FabricPath Feature Set

This chapter describes how to install and configure the FabricPath feature set on Cisco NX-OS devices.

Information About the FabricPath Feature Set

The Cisco Nexus 7000 Series device supports a large number of features that can be enabled at run time, often dependent on the licenses available on the device. Certain complex features cannot be dynamically loaded or unloaded. In earlier releases of Cisco NX-OS, these features were loaded at boot-time regardless if the feature was configured or actively being used on the device, which created problems since system resources (specifically, memory and CPU) were being consumed. There were also undesirable traces of the feature such as running services, binaries and libraries on the filesystem, configuration commands, device drivers, messaging opcodes, and other elements.

Feature sets were created to address these issues. A feature set is a collection of components that perform a specific set of functions.

You must install and enable the FabricPath feature set before you can configure the components that make up the feature set. See Cisco Nexus 7000 Series NX-OS FabricPath Configuration Guide, Release 5.x for configuration instructions.

Licensing Requirements for the FabricPath Feature Set

The following table shows the licensing requirements for the FabricPath feature set:

Product

License Requirement

Cisco NX-OS

FabricPath requires the Enhanced Layer 2 license. For an explanation of the licensing scheme, see the Cisco NX-OS Licensing Guide.

FabricPath Feature Set Guidelines and Limitations

The FabricPath feature set has the following guidelines and limitations:


  • You must install the Enhanced Layer 2 license before you can install and configure the FabricPath feature set.

  • You must install the FabricPath feature set in the default VDC before you can enable the feature set in any VDC (including the default VDC).

  • The FabricPath feature set operation may cause the standby supervisor to reload if it is in an unstable state, such as following a service failure or powering up. You can check whether the standby supervisor is stable with the show modules command. When the standby supervisor is stable, it is indicated as "ha-standby".

Default Settings for the FabricPath Feature Set

This table lists the default settings for the FabricPath feature set parameters.

Managing the FabricPath Feature Set

Follow these steps to manage the FabricPath feature set:

Procedure
Step 1   Installing The FabricPath Feature Set
Step 2   (Optional)Uninstalling the FabricPath Feature Set
Step 3   Enabling the FabricPath Feature Set
Step 4   (Optional)Disallowing the FabricPath Feature Set in a VDC

Installing The FabricPath Feature Set

You must install the FabricPath feature set in the default VDC.

Before You Begin

Ensure that you are in the default VDC.


Procedure
 Command or ActionPurpose
Step 1configure terminal


Example:
switch# configure terminal
switch(config)#
 

Enters configuration mode.

 
Step 2 install feature-set fabricpath


Example: 
switch(config)# install feature-set fabricpath
 

Installs the FabricPath feature set in the default VDC.

 
Step 3exit


Example:
switch(config)# exit
switch#
 

Exits configuration mode.

 

Uninstalling the FabricPath Feature Set

You can uninstall the FabricPath feature set.

Before You Begin

The FabricPath feature set must be installed in the default VDC.

The FabricPath feature set must not be enabled in any VDC.


Procedure
 Command or ActionPurpose
Step 1configure terminal


Example:
switch# configure terminal
switch(config)#
 

Enters configuration mode.

 
Step 2 no install feature-set fabricpath


Example: 
switch(config)# no install feature-set fabricpath
 

Uninstalls the FabricPath feature set. You cannot uninstall the feature set if it is enabled in any VDC.

 
Step 3exit


Example:
switch(config)# exit
switch#
 

Exits configuration mode.

 

Enabling the FabricPath Feature Set

You can enable the installed FabricPath feature set in any VDC on the device.

Before You Begin

Ensure that you have installed the FabricPath feature set in the default VDC.

Ensure that you are in the correct VDC or use the switchto vdc command.


Procedure
 Command or ActionPurpose
Step 1configure terminal


Example:
switch# configure terminal
switch(config)#
 

Enters configuration mode.

 
Step 2 feature-set fabricpath


Example: 
switch(config)# feature-set fabricpath
 

Enables the FabricPath feature set. The feature set must be installed before it shows as an option to this command.

 
Step 3exit


Example:
switch(config)# exit
switch#
 

Exits configuration mode.

 

Disabling the FabricPath Feature Set

You can disable the FabricPath feature set.

Before You Begin

Ensure that you have installed the FabricPath feature set in the default VDC.

Ensure that you are in the correct VDC or use the switchto vdc command.


Procedure
 Command or ActionPurpose
Step 1configure terminal


Example:
switch# configure terminal
switch(config)#
 

Enters configuration mode.

 
Step 2 no feature-set fabricpath


Example: 
switch(config)# no feature-set fabricpath
 

Disables the FabricPath feature set.

Note   

The no feature-set fabricpath command may take some time to complete if the size of the configuration is very large. The command must clean up all of the configurations associated with the FabricPath feature set.

 
Step 3exit


Example:
switch(config)# exit
switch#
 

Exits configuration mode.

 

Disallowing the FabricPath Feature Set in a VDC

By default, when you install the FabricPath feature set, it is allowed in all VDCs. You can disallow the installed FabricPath feature set in a VDC on the device.

Before You Begin

Ensure that you installed the FabricPath feature set in the default VDC.

Ensure that you have not enabled the FabricPath feature set in the specified VDC.


Procedure
 Command or ActionPurpose
Step 1configure terminal


Example:
switch# configure terminal
switch(config)#
 

Enters configuration mode.

 
Step 2vdc vdc_ID


Example:
switch(config)# vdc 1
 

Specifies a VDC and enters VDC configuration mode.

 
Step 3 no allow feature-set fabricpath


Example: 
switch(config-vdc)# no allow feature-set fabricpath
 

Disallows the FabricPath feature set in the VDC. You cannot disallow the FabricPath feature set if it is enabled in the specified VDC.

 
Step 4end


Example:
switch(config-vdc)# end
switch#
 

Exits VDC configuration mode and returns to EXEC mode.

 

Allowing the FabricPath Feature Set in a VDC

By default, the installed FabricPath feature set is allowed in all VDCs on the device. You can disallow the installed FabricPath feature set in a specific VDC. Subsequently, you can allow that disallowed FabricPath feature set in the VDC.

Before You Begin

Ensure that you have installed the FabricPath feature set in the default VDC.


Procedure
 Command or ActionPurpose
Step 1configure terminal


Example:
switch# configure terminal
switch(config)#
 

Enters configuration mode.

 
Step 2vdc vdc_ID


Example:
switch(config)# vdc 1
 

Specifies a VDC and enters VDC configuration mode.

 
Step 3 allow feature-set fabricpath


Example: 
switch(config-vdc)# allow feature-set fabricpath
 

Allows the FabricPath feature set in the VDC.

 
Step 4end


Example:
switch(config-vdc)# end
switch#
 

Exits VDC configuration mode and returns to EXEC mode.

 

Verifying Feature Sets

To display information about the configured feature sets including the FabricPath feature set, perform the following task:

Command Description
show feature-set

Displays the status of the feature sets on the device.

Configuration Example for the FabricPath Feature Set

The following example shows how to install the FabricPath feature set on the device and then switch to a VDC and enable the feature set in that VDC:

switch# configure terminal
switch(config)# install feature-set fabricpath
switch(config)# exit
switch# switchto vdc vdc1
switch-vdc1# configure terminal
switch-vdc1(config)# feature-set fabricpath
switch-vdc1(config)# switchback
switch#

Note

Instead of the switchto command, you can use the ssh command to connect to the management port of the VDC.

The following example shows how to install the FabricPath feature set in the default VDC on the device:

switch# configure terminal
switch(config)# install feature-set fabricpath
switch(config)# feature-set fabricpath
switch(config)# exit
switch#

The following example shows how to display the status of the feature sets on the device:

switch# show feature-set
Feature Set Name      ID        State
--------------------  --------  --------
fabricpath            2         enabled
fex                   3         disabled
switch#

The following example shows how to display the services used by the FabricPath feature set:

switch# show feature-set services fabricpath
u2rib
drap
isis_l2mp
3 services in feature set fabricpath
switch#
