Configuring Module Pre-Provisioning

This chapter contains the following sections:

Information About Module Pre-Provisioning

The pre-provisioning feature allows you to preconfigure interfaces before inserting or attaching a module. If a module goes offline, you can also use pre-provisioning to make changes to the interface configurations for the offline module. When a pre-provisioned module comes online, the pre-provisioning configurations are applied. If any configurations were not applied, a syslog is generated. The syslog lists the configurations that were not accepted.

In some Virtual Port Channel (vPC) topologies, pre-provisioning is required for the configuration synchronization feature. Pre-provisioning allows you to synchronize the configuration for an interface that is online with one peer but offline with another peer.

Guidelines and Limitations

Pre-provisioning has the following configuration guidelines and limitations:

  • When a module comes online, commands that are not applied are listed in the syslog.

  • If a slot is pre-provisioned for module A and if you insert module B into the slot, module B does not come online.

  • There is no MIB support for pre-provisioned interfaces.

  • Cisco DCNM is not supported.

Enabling Module Pre-Provisioning

You can enable pre-provisioning on a module that is offline. Enter the provision model model command in module pre-provision mode.

Note
After enabling pre-provisioning, you can configure the interfaces as though they are online.
Procedure
     Command or ActionPurpose
    Step 1 configuration terminal


    Example: 
    switch# config t
switch(config)#
     

    Enters global configuration mode.

     
    Step 2 slot slot


    Example: 
    switch(config)# slot 101
switch(config-slot)#
     

    Selects the slot to pre-provision and enters slot configuration mode.

     
    Step 3 provision model model


    Example: 
    switch(config-slot)# provision model N2K-C2248T
switch(config-slot)#
     

    Selects the module that you want to pre-provision.

     
    Step 4 exit


    Example: 
    switch(config-slot)# exit
switch#
     

    Exits slot configuration mode.

     
    Step 5 copy running-config startup-config


    Example: 
    switch# copy running-config startup-config
          		(Optional)

    Copies the running configuration to the startup configuration.

     

    This example shows how to select slot 101 and the N2K-C2232P module to pre-provision.

    switch# configure terminal
switch(config)# slot 101
switch(config-slot)# provision model N2K-C2232P 
switch(config-slot)# exit

    Removing Module Pre-Provisioning

    You can remove a module that has been pre-provisioned.

    Procedure
       Command or ActionPurpose
      Step 1 configuration terminal


      Example: 
      switch# config t
switch(config)#
       

      Enters global configuration mode.

       
      Step 2 slot slot


      Example: 
      switch(config)# slot 101
switch(config-slot)#
       

      Selects the slot to pre-provision and enters slot configuration mode.

       
      Step 3 no provision model model


      Example: 
      switch(config-slot)# no provision model N2K-C2248T
switch(config-slot)#
       

      Removes pre-provisioning from the module.

       
      Step 4 exit


      Example: 
      switch(config-slot)# exit
switch#
       

      Exits slot configuration mode.

       
      Step 5 copy running-config startup-config


      Example: 
      switch# copy running-config startup-config
              		(Optional)

      Copies the running configuration to the startup configuration.

       

      This example shows how to remove a preprovisioned module from a chassis slot:

      switch(config)# slot 2
switch(config-slot)# no provision model N5K-M1404
switch(config-slot)#

      Verifying the Pre-Provisioned Configuration

      To display the pre-provisioned configuration, perform one of the following tasks:

      Command Purpose
      show module Displays module information.
      show switch-profile Displays switch profile information.
      show running-config exclude-provision Displays the running configuration without the pre-provisioned interfaces or modules that are offline.
      show provision failed-config

      Displays the pre-provisioned commands that were not applied to the configuration when the interface or module came online.

      This command also displays a history of failed commands.

      show running-config Displays the running configuration including the pre-provisioned configuration.
      show startup-config Displays the startup configuration including the pre-provisioned configuration.

      Configuration Examples for Pre-Provisioning

      The following example shows how to enable pre-provisioning on slot 110 on the Cisco Nexus 2232P Fabric Extender and how to pre-provision interface configuration commands on the Ethernet 110/1/1 interface.

      switch# configure terminal
switch(config)# slot 110
switch(config-slot)# provision model N2K-C2232P 
switch(config-slot)# exit

switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# interface Ethernet110/1/1
switch(config-if)# description module is preprovisioned
switch(config-if)# show running-config interface Ethernet110/1/1

version 5.0(2)N1(1)

interface Ethernet110/1/1
  description module is preprovisioned

      The following example shows the list of pre-provisioned commands that were not applied when the module came online.

      switch(config-if-range)# show provision failed-config 101
The following config was not applied for slot 33

interface Ethernet101/1/2
  service-policy input test


interface Ethernet101/1/3
  service-policy input test

      This example shows how to remove all pre-provisioned modules from a slot:

      switch(config)# slot 2
switch(config-slot)# no provision model
switch(config-slot)#
