P Commands

This chapter describes the Cisco NX-OS commands that begin with P that are used to manage a Cisco Nexus 2000 Series Fabric Extender from a Cisco Nexus 6000 switch.

pinning max-links

To specify the number of statically pinned uplinks, use the pinning max-links command. To reset to the default, use the no form of this command.

pinning max-links uplinks

no pinning max-links

Syntax Description

uplinks

Number of uplinks. The range is from 1 to 8. The default is 1.

This command is applicable only if the Fabric Extender is connected to its parent switch using one or more statically pinned fabric interfaces.


Command Default

The default number of uplinks is 1.

Command Modes

Fabric extender configuration mode

Command History

Release
Modification

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

Use the pinning max-links command when you create a number of pinned fabric interface connections to enable the parent switch to determine a distribution of host interfaces. The host interfaces are divided by the number of uplinks and distributed accordingly.

Caution Changing the value of uplinks is disruptive. All the host interfaces on the Fabric Extender are brought down and back up as the parent switch reassigns its static pinning.

Examples

This example shows how to specify the number of statically pinned uplinks for a Fabric Extender: 

switch# configure terminal

switch(config)# fex 101

switch(config-fex)# pinning max-links 4

 
   
 
    
   
 This example shows how to revert to the uplink count to the default for a Fabric Extender: 
 
    
   
 
    
switch# configure terminal

 
   
 
    
   
 
    
switch(config)# fex 101

 
   
 
    
   
 
    
switch(config-fex)# no pinning max-links

 Usage Guidelines 
 
    
   
 Use this command to define the modules (line card or Cisco Nexus 2000 Series Fabric Extender) to preprovision. If the card type does not match the card in the slot or the module is not compatible with the chassis, you see the following messages: 
 
    
   
 
    
ERROR: The card type does not match the card in slot

 
   
 
    
   
 
    
 
   
 
    
   
 or 
 
    
   
 
    
ERROR: This module cannot be configured for this chassis

 
   
 
    
   
 
    
 
   
 
    
   
 You can configure features or interfaces (Ethernet, Fibre Channel) on the modules before the modules are inserted in the switch chassis. You can also use this command to manage the configuration of these features or interfaces when the module is offline due to a failure or scheduled downtime. These configurations are applied when the module comes online. 
 
    
   
 When you preprovision a module by specifying the type of module, platform manager will allow only modules of matching type to come online. If you configure the interfaces for the module without specifying the module type, the configuration is applied when the module comes online, regardless of the module type. 
 
    
   
 You can preprovision modules and interfaces in a switch profile. The modules and interfaces are preprovisioned when you apply (commit) the switch profile. Once the module is inserted and interfaces are created, the preprovisioning module passes on the configuration to the respective applications before the interfaces come up. 
 
    
   
 Mutual exclusion is a mechanism where configuration outside the switch profile is not allowed in the switch profile and vice-versa. This requirement is to ensure that configuration in the switch profile is exactly the same on both switches. Preprovisioned configuration is the same as a configuration when the module is online, so mutual exclusion checks would continue to apply normally. 
 
    
   
 Examples 
 
    
   
 This example shows how to preprovision a module in slot 2 of the chassis: 
 
    
   
 
    
switch(config)# slot 2

 
   
 
    
   
 
    
switch(config-slot)# provision model N5K-M1404

 
   
 
    
   
 
    
switch(config-slot)#

 
   
 
    
   
 
    
 
   
 
    
   
 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)#

 
   
 
    
   
 
    
 
   
 
    
   
 This example shows how to remove all preprovisioned modules or line cards from a chassis slot: 
 
    
   
 
    
switch(config)# slot 2

 
   
 
    
   
 
    
switch(config-slot)# no provision model

 
   
 
    
   
 
    
switch(config-slot)#
