Configuring the Fabric Extender

This chapter describes how to configure a Cisco Nexus 2000 Series Fabric Extender using the Cisco Nexus 5000 Series switch and includes the following sections:

Information About Associating a Fabric Extender to a Fabric Interface

A Cisco Nexus 2000 Series Fabric Extender is connected to its parent device through physical Ethernet interfaces or an EtherChannel. By default, the parent device does not allow the attached Fabric Extender to connect until it has been assigned a FEX-number and is associated with the connected interface.


Note

The Fabric Extender may connect to the switch through a number of separate physical Ethernet interfaces or one EtherChannel interface.


Note

You must enable the Fabric Extender functionality before you can configure and use a Fabric Extender connected to the parent switch.

      Disassociating a Fabric Extender From an Interface

      You can disassociate the Fabric Extender from an interface.

      Before You Begin

      Ensure that you have enabled the Fabric Extender feature.

      Procedure
         Command or ActionPurpose
        Step 1 switch# configure terminal
         

        Enters configuration mode.

         
        Step 2 switch(config)# interface {ethernet slot/port | port-channel channel}
         

        Specifies the interface to configure. The interface can be an Ethernet interface or a EtherChannel.

         
        Step 3 switch(config-if)# no fex associate
         

        Disassociates the Fabric Extender unit attached to the interface.

         

        Configuring Fabric Extender Global Features

        You can configure global features for a Fabric Extender.

        Before You Begin

        Ensure that you have enabled the Fabric Extender feature.

        Procedure
           Command or ActionPurpose
          Step 1 switch# configure terminal
           

          Enters configuration mode.

           
          Step 2 switch(config)# fex FEX-number
           

          Enters configuration mode for the specified Fabric Extender. The range of the FEX-number is from 100 to 199.

           
          Step 3 switch(config-fex)# description desc
                      		(Optional)

          Specifies the description. The default is the string FEXxxxx where xxxx is the FEX-number. If the FEX-number is 123, the description is FEX0123.

           
          Step 4 switch(config-fex)# no description
                      		(Optional)

          Deletes the description.

           
          Step 5switch(config-fex)# type FEX-type
                      		(Optional)

          Specifies the type of Fabric Extender. The FEX-type is one of N2148T for the 48 1000BASE-T Ethernet host interfaces and 4 10-Gigabit Ethernet fabric interfaces module, N2232P for the 32 10-Gigabit Ethernet host interfaces and 4 10-Gigabit Ethernet fabric interfaces module, or N2248T for the 48 100Base-T/1000BASE-T Ethernet host interfaces and 4 10-Gigabit Ethernet fabric interfaces module

          The parent device remembers the type of the Fabric Extender in its binary configuration. When this feature is configured, the Fabric Extender is only allowed to come online if its type matches the configured FEX-type.

           
          Step 6switch(config-fex)# no type
                      		(Optional)

          Deletes the FEX-type. In this case, when a Fabric Extender is connected to the fabric interfaces and does not match the configured type previously saved in the binary configuration on the parent device, all configurations for all interfaces on the Fabric Extender are deleted.

           
          Step 7 switch(config-fex)# pinning max-links uplinks
                      		(Optional)

          Defines the number of uplinks. The default is 1. The range is from 1 to 4.

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

          Caution   

          Changing the number of uplinks with the pinning max-links command disrupts all the host interface ports of the Fabric Extender.

           
          Step 8 switch(config-fex)# no pinning max-links
                      		(Optional)

          Resets the number of uplinks to the default.

          Caution   

          Changing the number of uplinks with the no pinning max-links command disrupts all the host interface ports of the Fabric Extender.

           
          Step 9 switch(config-fex)# serial serial
                      		(Optional)

          Defines a serial number string. If this command is configured, then a switch will only allow the corresponding chassis ID to associate (using the fex associate command) if the Fabric Extender reports a matching serial number string.

          Caution   

          Configuring a serial number other than that of the given Fabric Extender will force the Fabric Extender offline.

           
          Step 10 switch(config-fex)# no serial
                      		(Optional)

          Deletes the serial number string.

           

          Enabling the Fabric Extender Locator LED

          You can toggle on the locator beacon LED. It allows you to locate a specific Fabric Extender in a rack.

          Procedure
             Command or ActionPurpose
            Step 1 switch# locator-led fex FEX-number
             

            Turns on the locator beacon LED for a specific Fabric Extender.

             
            Step 2 switch# no locator-led fex FEX-number
                          		(Optional)

            Turns off the locator beacon LED for a specific Fabric Extender.

             

            Redistributing the Links

            When you provision the Fabric Extender with statically pinned interfaces, the downlink host interfaces on the Fabric Extender are pinned to the fabric interfaces in the order they were initially configured. If you want to maintain a specific relationship of host interfaces to fabric interface across reboots, you should repin the links.

            You may want to perform this function in these two situations:

            • A change in the max-links configuration.
            • If you need to maintain the pinning order of host interfaces to fabric interfaces.

            Changing the Number of Links

            If you initially configured a specific port on the parent switch, for example port 33, as your only fabric interface, all 48 host interfaces are pinned to this port. If you provision another port, for example 35, then you must enter the pinning max-links 2 command to redistribute the host interfaces. All host interfaces are brought down and host interfaces 1 to 24 are pinned to fabric interface 33 and host interfaces 25 to 48 are pinned to fabric interface 35.

            Maintaining the Pinning Order

            The pinning order of the host interfaces is initially determined by the order in which the fabric interfaces were configured. In this example, four fabric interfaces were configured in the following order: 

            switch# show interface ethernet 1/35 fex-intf
Fabric           FEX
Interface        Interfaces
---------------------------------------------------
 Eth1/35         Eth100/1/12   Eth100/1/11   Eth100/1/10   Eth100/1/9
                 Eth100/1/8    Eth100/1/7    Eth100/1/6    Eth100/1/5
                 Eth100/1/4    Eth100/1/3    Eth100/1/2    Eth100/1/1

                 Eth100/1/16   Eth100/1/15   Eth100/1/14   Eth100/1/13

switch# show interface ethernet 1/38 fex-intf

---------------------------------------------------
 Eth1/38         Eth100/1/36   Eth100/1/35   Eth100/1/34   Eth100/1/33
                 Eth100/1/32   Eth100/1/31   Eth100/1/30   Eth100/1/29
                 Eth100/1/28   Eth100/1/27   Eth100/1/26   Eth100/1/25

switch# show interface ethernet 1/40 fex-intf
Fabric           FEX
Interface        Interfaces
---------------------------------------------------
 Eth1/40         Eth100/1/48   Eth100/1/47   Eth100/1/46   Eth100/1/45
                 Eth100/1/44   Eth100/1/43   Eth100/1/42   Eth100/1/41
                 Eth100/1/40   Eth100/1/39   Eth100/1/38   Eth100/1/37

            The next time that you reboot the Fabric Extender, the configured fabric interfaces are pinned to the host interfaces in an ascending order by port number of the fabric interface. If you want to configure the same fixed distribution of host interfaces without restarting the Fabric Extender, enter the fex pinning redistribute command.

            Redistributing Host Interfaces

            You can redistribute the host interfaces on the Fabric Extender. Enter the fex pinning redistribute FEX-number command to redistribute the host connections. The range of the FEX-number is from 100 to 199.

            This example shows how to redistribute the host interfaces on a Fabric Extender: 

            switch# fex pinning redistribute 100

            Caution

            The fex pinning redistribute command disrupts all the host interface ports of the Fabric Extender.

            Upgrading the Fabric Extender

            You upgrade the Fabric Extender by upgrading the software on its parent device.


            Note

            You must have the network-admin role before you can upgrade the software image on the parent device.

            You must log into the parent device on its console port connection.

            The installation process upgrades both the parent switch and the Fabric Extender at the same time. The process is designed to minimize traffic disruption to the connected hosts.

            Procedure
              Step 1   Download the new kickstart and system images to the parent switch.
              Step 2   Enter the install all kickstart new-kickstart-url system new-system-url command.

              The switch pushes the new software image to the Fabric Extender then both the switch and the Fabric Extender reboot. The downtime for the hosts connected to the Fabric Extender is the time required for the parent switch and Fabric Extender to reload, configure, and stabilize.

              Upgrading the Fabric Extender in a vPC Topology

              The Fabric Extender can be deployed in a virtual port channel (vPC) topology. Using a vPC to connect the Fabric Extender to two switches makes the upgrade process less disruptive to the connected hosts.


              Note

              You must have the network-admin role before you can upgrade the software image on the parent device.

              You must log into the parent device on its console port connection.

              Performing a Simultaneous Fabric Extender Upgrade

              You can perform a simultaneous upgrade of the entire setup.

              Procedure
                Step 1   Download the new kickstart and system images to both the vPC primary and secondary parent devices.
                Step 2   Enter the install all kickstart new-kickstart-url system new-system-url command on both switches.
                Note   

                The Fabric Extender will be upgraded by either the vPC primary or the secondary device.

                The downtime for the hosts connected to the Fabric Extender in a simultaneous upgrade is the time required for the parent devices and the Fabric Extender to reload, configure, and stabilise.

                Performing an Active-Active Fabric Extender Upgrade

                You can reduce the length of the downtime for the hosts connected to the Fabric Extender by performing an installation pending upgrade of your dual homed Fabric Extender (Active-Active) vPC topology setup.

                Figure 1. Dual Homed Fabric Extender vPC Topology


                Note

                The previous figure shows that only one Fabric Extender is connected to the parent devices. In most configurations, you would typically have more than one Fabric Extender connected to the parent devices. The following procedure is the same when you have one or more than one Fabric Extender.

                Procedure
                  Step 1   Download the new kickstart and system images to both the vPC primary and secondary parent devices.
                  Step 2   Enter the install all kickstart new-kickstart-url system new-system-url command on one of the devices (NX-5000-1 in the previous figure).
                  Step 3   The first device (NX-5000-1) and the attached Fabric Extender are now upgraded. When the device reboots to complete its upgrade, the Fabric Extender stays online and enters the installation pending mode. In this mode, the Fabric Extender stays connected to the other device (NX-5000-2 in the previous figure) and continues to forward traffic to and from its attached hosts.
                  Step 4   Confirmed that the upgraded device (NX-5000-1) and the Fabric Extender are operational.
                  Step 5   Enter the install all kickstart new-kickstart-url system new-system-url command on the second switch (NX-5000-2). When the upgrade is complete, the NX-5000-2 and the Fabric Extender will reboot.

                  Once the second upgraded switch (NX-5000-2) is operational, the Fabric Extender will reconnect to both the switches and once again be dual-homed.
