Configuring Ports and Port Channels

Contents

Configuring Ports and Port Channels

This chapter includes the following sections:

Server and Uplink Ports on the 6100 Series Fabric Interconnect

Each 6100 series fabric interconnect has a set of ports in a fixed port module that you can configure as either server ports or uplink Ethernet ports. These ports are not reserved. They cannot be used by a Cisco UCS domain until you configure them. You can add expansion modules to increase the number of uplink ports on the fabric interconnect or to add uplink Fibre Channel ports to the fabric interconnect.

You need to create LAN pin groups and SAN pin groups to pin traffic from servers to an uplink port.


Note


Ports on the 6100 series fabric interconnect are not unified. For more information on Unified Ports, see Unified Ports.


Each fabric interconnect can include the following port types:

Server Ports

Server ports handle data traffic between the fabric interconnect and the adapter cards on the servers.

You can only configure server ports on the fixed port module. Expansion modules do not include server ports.

Uplink Ethernet Ports

Uplink Ethernet ports handle Ethernet traffic between the fabric interconnect and the next layer of the network. All network-bound Ethernet traffic is pinned to one of these ports.

By default, Ethernet ports are unconfigured. However, you can configure them to function in the following ways:
  • Uplink
  • FCoE
  • Appliance

You can configure uplink Ethernet ports on either the fixed module or an expansion module.

Uplink Fibre Channel Ports

Uplink Fibre Channel ports handle FCoE traffic between the fabric interconnect and the next layer of the storage area network. All network-bound FCoE traffic is pinned to one of these ports.

By default, Fibre Channel ports are uplink. However, you can configure them to function as Fibre Channel storage ports. This is useful in cases where Cisco UCS requires a connection to a Direct-Attached Storage (DAS) device.

You can only configure uplink Fibre Channel ports on an expansion module. The fixed module does not include uplink Fibre Channel ports.

Unified Ports on the 6200 Series Fabric Interconnect

Unified ports are ports on the 6200 series fabric interconnect that can be configured to carry either Ethernet or Fibre Channel traffic. These ports are not reserved. They cannot be used by a Cisco UCS domain until you configure them.

Configurable beacon LEDs indicate which unified ports are configured for the selected port mode.

Port Modes

The port mode determines whether a unified port on the fabric interconnect is configured to carry Ethernet or Fibre Channel traffic. The port mode is not automatically discovered by the fabric interconnect; it is configured in Cisco UCS Manager.

Changing the port mode results in the existing port configuration being deleted and replaced by a new logical port. Any objects associated with that port configuration, such as VLANs and VSANS, are removed. There is no restriction on the number of times the port mode can be changed for a unified port.

Port Types

The port type defines the type of traffic carried over a unified port connection.

All of the port types listed are configurable on both the fixed and expansion module, including server ports, which are not configurable on the 6100 series fabric interconnect expansion module, but are configurable on the 6200 series fabric interconnect expansion module.

By default, unified ports changed to Ethernet port mode are set to uplink Ethernet port type. unified ports changed to Fibre Channel port mode are set to the Fibre Channel uplink port type. Fibre Channel ports cannot be unconfigured.

Changing the port type does not require a reboot.

When the port mode is set to Ethernet, you can configure the following port types:

  • Server ports
  • Ethernet uplink ports
  • Ethernet port channel members
  • FCoE ports
  • Appliance ports
  • Appliance port channel members
  • SPAN destination ports
  • SPAN source ports

    Note


    For SPAN source ports, configure one of the port types and then configure the port as SPAN source.


When the port mode is set to Fibre Channel, you can configure the following port types:

  • Fibre Channel uplink ports
  • Fibre Channel port channel members
  • Fibre Channel storage ports
  • SPAN destination ports
  • SPAN source ports

    Note


    For SPAN source ports, configure one of the port types and then configure the port as SPAN source.


Beacon LEDs for Unified Ports

Each port on the 6200 series fabric interconnect has a corresponding beacon LED. When the Beacon LED property is configured, the beacon LEDs illuminate, showing you which ports are configured in a given port mode.

The Beacon LED property can be configured to show you which ports are grouped in one port mode: either Ethernet or Fibre Channel. By default, the Beacon LED property is set to Off.


Note


For unified ports on the expansion module, the Beacon LED property may be reset to the default value of Off during expansion module reboot.


Guidelines for Configuring Unified Ports

Consider the following guidelines and restrictions when configuring unified ports:

Hardware and Software Requirements

Unified ports are supported on the 6200 series fabric interconnect with Cisco UCS Manager, version 2.0.

Unified ports are not supported on 6100 series fabric interconnects, even if they are running Cisco UCS Manager, version 2.0.

Port Mode Placement

Because the Cisco UCS Manager GUI interface uses a slider to configure the port mode for unified ports on a fixed or expansion module, it automatically enforces the following restrictions which limits how port modes can be assigned to unified ports. When using the Cisco UCS Manager CLI interface, these restrictions are enforced when you commit the transaction to the system configuration. If the port mode configuration violates any of the following restrictions, the Cisco UCS Manager CLI displays an error:

  • Ethernet ports must be grouped together in a block. For each module (fixed or expansion), the Ethernet port block must start with the first port and end with an even numbered port.
  • Fibre Channel ports must be grouped together in a block. For each module (fixed or expansion), the first port in the Fibre Channel port block must follow the last Ethernet port and extend to include the rest of the ports in the module. For configurations that include only Fibre Channel ports, the Fibre Channel block must start with the first port on the fixed or expansion module.
  • Alternating Ethernet and Fibre Channel ports is not supported on a single module.

Example of a valid configuration— Might include unified ports 1–16 on the fixed module configured in Ethernet port mode and ports 17–32 in Fibre Channel port mode. On the expansion module you could configure ports 1–4 in Ethernet port mode and then configure ports 5–16 in Fibre Channel mode. The rule about alternating Ethernet and Fibre Channel port types is not violated because this port arrangement complies with the rules on each individual module.

Example of an invalid configuration— Might include a block of Fibre Channel ports starting with port 16. Because each block of ports has to start with an odd-numbered port, you would have to start the block with port 17.


Note


The total number of uplink Ethernet ports and uplink Ethernet port channel members that can be configured on each fabric interconnect is limited to 31. This limitation includes uplink Ethernet ports and uplink Ethernet port channel members configured on the expansion module.


Special Considerations for UCS Manager CLI Users

Because the Cisco UCS Manager CLI does not validate port mode changes until you commit the buffer to the system configuration, it is easy to violate the grouping restrictions if you attempt to commit the buffer before creating at least two new interfaces. To prevent errors, we recommend that you wait to commit your changes to the system configuration until you have created new interfaces for all of the unified ports changing from one port mode to another.

Commiting the buffer before configuring multiple interfaces will result in an error, but you do not need to start over. You can continue to configure unified ports until the configuration satisfies the aforementioned requirements.

Effect of Port Mode Changes on Data Traffic

Port mode changes can cause an interruption to the data traffic for the Cisco UCS domain. The length of the interruption and the traffic that is affected depend upon the configuration of the Cisco UCS domain and the module on which you made the port mode changes.


Tip


To minimize the traffic disruption during system changes, form a Fibre Channel uplink port-channel across the fixed and expansion modules.


Impact of Port Mode Changes on an Expansion Module

After you make port mode changes on an expansion module, the module reboots. All traffic through ports on the expansion module is interrupted for approximately one minute while the module reboots.

Impact of Port Mode Changes on the Fixed Module in a Cluster Configuration

A cluster configuration has two fabric interconnects. After you make port changes to the fixed module, the fabric interconnect reboots. The impact on the data traffic depends upon whether or not you have configured the server vNICs to failover to the other fabric interconnect when one fails.

If you change the port modes on the expansion module of one fabric interconnect and then wait for that to reboot before changing the port modes on the second fabric interconnect, the following occurs:

  • With server vNIC failover, traffic fails over to the other fabric interconnect and no interruption occurs.
  • Without server vNIC failover, all data traffic through the fabric interconnect on which you changed the port modes is interrupted for approximately eight minutes while the fabric interconnect reboots.

However, if you change the port modes on the fixed modules of both fabric interconnects simultaneously, all data traffic through the fabric interconnects are interrupted for approximately eight minutes while the fabric interconnects reboot.

Impact of Port Mode Changes on the Fixed Module in a Standalone Configuration

A standalone configuration has only one fabric interconnect. After you make port changes to the fixed module, the fabric interconnect reboots. All data traffic through the fabric interconnect is interrupted for approximately eight minutes while the fabric interconnect reboots.

Configuring the Port Mode


Caution


Changing the port mode on either module can cause an interruption in data traffic because changes to the fixed module require a reboot of the fabric interconnect and changes on an expansion module require a reboot of that module.

If the Cisco UCS domain has a cluster configuration that is set up for high availability and servers with service profiles that are configured for failover, traffic fails over to the other fabric interconnect and data traffic is not interrupted when the port mode is changed on the fixed module.


In the Cisco UCS Manager CLI, there are no new commands to support Unified Ports. Instead, you change the port mode by scoping to the mode for the desired port type and then creating a new interface. When you create a new interface for an already configured slot ID and port ID, UCS Manager deletes the previously configured interface and creates a new one. If a port mode change is required because you configure a port that previously operated in Ethernet port mode to a port type in Fibre Channel port mode, UCS Manager notes the change.

Procedure
      Command or Action Purpose
    Step 1 UCS-A# scope port-type-mode
     

    Enters the specified port type mode for one of the following port types:

    eth-server

    For configuring server ports.

    eth-storage

    For configuring Ethernet storage ports and Ethernet storage port channels.

    eth-traffic-mon

    For configuring Ethernet SPAN ports.

    eth-uplink

    For configuring Ethernet uplink ports.

    fc-storage

    For configuring Fibre Channel storage ports.

    fc-traffic-mon

    For configuring Fibre Channel SPAN ports.

    fc-uplink

    For configuring Fibre Channel uplink ports and Fibre Channel uplink port channels.

     
    Step 2 UCS-A /port-type-mode # scope fabric {a | b} 

    Enters the specified port type mode for the specified fabric.

     
    Step 3 UCS-A /port-type-mode/fabric # create interface slot-id port-id 

    Creates an interface for the specified port type.

    If you are changing the port type from Ethernet port mode to Fibre Channel port mode, or vice-versa, the following warning appears:

    Warning: This operation will change the port mode (from Ethernet to FC or vice-versa). When committed, this change will require the module to restart.

     
    Step 4 Create new interfaces for other ports belonging to the Ethernet or Fibre Channel port block. 

    There are several restrictions that govern how Ethernet and Fibre Channel ports can be arranged on a fixed or expansion module. Among other restrictions, it is required that you change ports in groups of two. Violating any of the restrictions outlined in the Guidelines and Recommendations for Configuring Unified Ports section will result in an error.

     
    Step 5 UCS-A /port-type-mode/fabric/interface # commit-buffer 

    Commits the transaction to the system configuration.

     

    Depending upon the module for which you configured the port modes, data traffic for the Cisco UCS domain is interrupted as follows:

    • Fixed module—The fabric interconnect reboots. All data traffic through that fabric interconnect is interrupted. In a cluster configuration that provides high availability and includes servers with vNICs that are configured for failover, traffic fails over to the other fabric interconnect and no interruption occurs. Changing the port mode for both sides at once results in both fabric interconnects rebooting simultaneously and a complete loss of traffic until both fabric interconnects are brought back up. It takes about 8 minutes for the fixed module to reboot.
    • Expansion module—The module reboots. All data traffic through ports in that module is interrupted. It takes about 1 minute for the expansion module to reboot.

    The following example changes ports 9 and 10 on slot 1 from Ethernet uplink ports in Ethernet port mode to uplink Fibre Channel ports in Fibre Channel port mode:

    UCS-A# scope fc-uplink
    UCS-A /fc-uplink # scope fabric a
    UCS-A /fc-uplink/fabric # create interface 1 9
    Warning: This operation will change the port mode (from Ethernet to FC or vice-versa). 
    When committed, this change will require the fixed module to restart.
    UCS-A /fc-uplink/fabric/interface* # up
    UCS-A /fc-uplink/fabric* #create interface 1 10
    Warning: This operation will change the port mode (from Ethernet to FC or vice-versa). 
    When committed, this change will require the fixed module to restart.
    UCS-A /fc-uplink/fabric/interface* #commit-buffer

    Configuring the Beacon LEDs for Unified Ports

    Complete the following task for each module for which you want to configure beacon LEDs.

    Procedure
        Command or Action Purpose
      Step 1 UCS-A# scope fabric-interconnect {a | b}
       

      Enters fabric interconnect mode for the specified fabric.

       
      Step 2 UCS-A /fabric # scope card slot-id
       

      Enters card mode for the specified fixed or expansion module.

       
      Step 3 UCS-A /fabric/card # scope beacon-led
       

      Enters beacon LED mode.

       
      Step 4 UCS-A /fabric/card/beacon-led # set admin-state {eth | fc | off}
       

      Specifies which port mode is represented by illuminated beacon LED lights.

      eth

      All of the Unified Ports configured in Ethernet mode illuminate.

      fc

      All of the Unified Ports configured in Fibre Channel mode illuminate.

      off

      Beacon LED lights for all ports on the module are turned off.

       
      Step 5 UCS-A /fabric/card/beacon-led # commit-buffer
       

      Commits the transaction to the system configuration.

       

      The following example illuminates all of the beacon lights for Unified Ports in Ethernet port mode and commits the transaction:

      UCS-A# scope fabric-interconnect a
      UCS-A /fabric # scope card 1
      UCS-A /fabric/card # scope beacon-led
      UCS-A /fabric/card/beacon-led # set admin-state eth
      UCS-A /fabric/card/beacon-led* # commit-buffer
      UCS-A /fabric/card/beacon-led #

      Server Ports

      Configuring a Server Port

      You can only configure server ports on the fixed port module. Expansion modules do not include server ports.

      Procedure
          Command or Action Purpose
        Step 1 UCS-A# scope eth-server  

        Enters Ethernet server mode.

         
        Step 2 UCS-A /eth-server # scope fabric {a | b}  

        Enters Ethernet server fabric mode for the specified fabric.

         
        Step 3 UCS-A /eth-server/fabric # create interface slot-num port-num  

        Creates an interface for the specified Ethernet server port.

         
        Step 4 UCS-A /eth-server/fabric # commit-buffer  

        Commits the transaction to the system configuration.

         

        The following example creates an interface for Ethernet server port 12 on slot 1 of fabric B and commits the transaction:

        UCS-A# scope eth-server
        UCS-A /eth-server # scope fabric b
        UCS-A /eth-server/fabric # create interface 1 12
        UCS-A /eth-server/fabric* # commit-buffer
        UCS-A /eth-server/fabric # 
        

        Unconfiguring a Server Port

        Procedure
            Command or Action Purpose
          Step 1 UCS-A# scope eth-server  

          Enters Ethernet server mode.

           
          Step 2 UCS-A /eth-server # scope fabric {a | b}  

          Enters Ethernet server fabric mode for the specified fabric.

           
          Step 3 UCS-A /eth-server/fabric # delete interface slot-num port-num  

          Deletes the interface for the specified Ethernet server port.

           
          Step 4 UCS-A /eth-server/fabric # commit-buffer  

          Commits the transaction to the system configuration.

           

          The following example unconfigures Ethernet server port 12 on slot 1 of fabric B and commits the transaction:

          UCS-A# scope eth-server
          UCS-A /eth-server # scope fabric b
          UCS-A /eth-server/fabric # delete interface 1 12
          UCS-A /eth-server/fabric* # commit-buffer
          UCS-A /eth-server/fabric #
           

          Uplink Ethernet Ports

          Configuring an Uplink Ethernet Port

          You can configure uplink Ethernet ports on either the fixed module or an expansion module.

          Procedure
              Command or Action Purpose
            Step 1 UCS-A# scope eth-uplink  

            Enters Ethernet uplink mode.

             
            Step 2 UCS-A /eth-uplink # scope fabric {a | b}  

            Enters Ethernet uplink fabric mode for the specified fabric.

            Creates an interface for the specified Ethernet uplink port.

             
            Step 4 UCS-A /eth-uplink/fabric # set speed {10gbps | 1gbps}   (Optional)
            Sets the speed for the specified Ethernet uplink port.
            Note   

            For the 6100 series fabric interconnects, the admin speed is only configurable for the first eight ports on a 20-port fabric interconnect and the first 16 ports on a 40-port fabric interconnect.

             
            Step 5 UCS-A /eth-uplink/fabric # commit-buffer  

            Commits the transaction to the system configuration.

             

            The following example creates an interface for Ethernet uplink port 3 on slot 2 of fabric B, sets the speed to 10 gbps, and commits the transaction:

            UCS-A# scope eth-uplink
            UCS-A /eth-uplink # scope fabric b 
            UCS-A /eth-uplink/fabric # create interface 2 3
            UCS-A /eth-uplink/fabric # set speed 10gbps
            UCS-A /eth-uplink/fabric* # commit-buffer
            UCS-A /eth-uplink/fabric # 
            

            Unconfiguring an Uplink Ethernet Port

            Procedure

              Step 1 UCS-A# scope eth-uplink  

              Enters Ethernet uplink mode.

               
              Step 2 UCS-A /eth-uplink # scope fabric {a | b}  

              Enters Ethernet uplink fabric mode for the specified fabric.

               
              Step 3 UCS-A /eth-uplink/fabric # delete interface slot-num port-num  

              Deletes the interface for the specified Ethernet uplink port.

               
              Step 4 UCS-A /eth-uplink/fabric # commit-buffer  

              Commits the transaction to the system configuration.

               

              The following example unconfigures Ethernet uplink port 3 on slot 2 of fabric B and commits the transaction:

              UCS-A# scope eth-uplink
              UCS-A /eth-uplink # scope fabric b 
              UCS-A /eth-uplink/fabric # delete interface 2 3
              UCS-A /eth-uplink/fabric* # commit-buffer
              UCS-A /eth-uplink/fabric # 
               

              Appliance Ports

              Appliance ports are only used to connect fabric interconnects to directly attached NFS storage.

              Configuring an Appliance Port

              You can configure Appliance ports on either the fixed module or an expansion module.

              Procedure
                  Command or Action Purpose
                Step 1 UCS-A# scope eth-storage  

                Enters Ethernet storage mode.

                 
                Step 2 UCS-A /eth-storage # scope fabric{a | b}  

                Enters Ethernet storage mode for the specified fabric.

                 
                Step 3 UCS-A /eth-storage/fabric # create interface slot-num port-num  

                Creates an interface for the specified appliance port.

                 
                Step 4 UCS-A /eth-storage/fabric/interface # set portmode {access | trunk}   (Optional)

                Specifies whether the port mode is access or trunk. By default, the mode is set to trunk.

                 
                Step 5 UCS-A /eth-storage/fabric/interface # set pingroupname pin-group name   (Optional)

                Specifies the appliance pin target to the specified fabric and port, or fabric and port channel.

                 
                Step 6 UCS-A /eth-storage/fabric/interface # set prio sys-class-name   (Optional)

                Specifies the QoS class for the appliance port. By default, the priority is set to best-effort.

                The sys-class-name argument can be one of the following class keywords:

                • Fc—Use this priority for QoS policies that control vHBA traffic only.
                • Platinum—Use this priority for QoS policies that control vNIC traffic only.
                • Gold—Use this priority for QoS policies that control vNIC traffic only.
                • Silver—Use this priority for QoS policies that control vNIC traffic only.
                • Bronze—Use this priority for QoS policies that control vNIC traffic only.
                • Best Effort—Do not use this priority. It is reserved for the Basic Ethernet traffic lane. If you assign this priority to a QoS policy and configure another system class as CoS 0, Cisco UCS Manager does not default to this system class. It defaults to the priority with CoS 0 for that traffic.
                 
                Step 7 UCS-A /eth-storage/fabric/interface # set adminspeed {10gbps | 1 gbps}   (Optional)

                Specifies the admin speed for the interface. By default, the admin speed is set to 10gbps.

                 
                Step 8 UCS-A /eth-storage/fabric/interface # commit buffer  

                Commits the transaction to the system configuration.

                 

                The following example creates an interface for an appliance port 2 on slot 3 of fabric B, sets the port mode to access, pins the appliance port to a pin group called pingroup1, sets the QoS class to fc, sets the admin speed to 10 gbps, and commits the transaction:

                UCS-A# scope eth-storage
                UCS-A /eth-storage # scope fabric b
                UCS-A /eth-storage/fabric # create interface 3 2
                UCS-A /eth-storage/fabric* # set portmode access
                UCS-A /eth-storage/fabric* # set pingroupname pingroup1
                UCS-A /eth-storage/fabric* # set prio fc
                UCS-A /eth-storage/fabric* # set adminspeed 10gbps
                UCS-A /eth-storage/fabric* # commit-buffer
                UCS-A /eth-storage/fabric #
                What to Do Next

                Assign a VLAN or target MAC address for the appliance port.

                Assigning a Target MAC Address to an Appliance Port or Appliance Port Channel

                The following procedure assigns a target MAC address to an appliance port. To assign a target MAC address to an appliance port channel, scope to the port channel instead of the interface.

                Procedure
                    Command or Action Purpose
                  Step 1 UCS-A# scope eth-storage  

                  Enters Ethernet storage mode.

                   
                  Step 2 UCS-A /eth-storage # scope fabric{a | b}  

                  Enters Ethernet storage mode for the specified fabric.

                   
                  Step 3 UCS-A /eth-storage/fabric # scope interface slot-id port-id  
                  Enters Ethernet interface mode for the specified interface.
                  Note   

                  To assign a target MAC address to an appliance port channel, use the scope port-channel command instead of scope interface .

                   
                  Step 4 UCS-A /eth-storage/fabric/interface # create eth-target eth-target name  

                  Specifies the name for the specified MAC address target.

                   
                  Step 5 UCS-A /eth-storage/fabric/interface/eth-target # set mac-address mac-address  

                  Specifies the MAC address in nn:nn:nn:nn:nn:nn format.

                   

                  The following example assigns a target MAC address for an appliance device on port 3, slot 2 of fabric B and commits the transaction:

                  UCS-A# scope eth-storage
                  UCS-A /eth-storage* # scope fabric b
                  UCS-A /eth-storage/fabric* # scope interface 2 3

                  UCS-A /eth-storage/fabric/interface* # set mac-address 01:23:45:67:89:ab
                  UCS-A /eth-storage/fabric/interface* # commit-buffer
                  UCS-A /eth-storage/fabric #

                  The following example assigns a target MAC address for appliance devices on port channel 13 of fabric B and commits the transaction:

                  UCS-A# scope eth-storage

                          Default Zoning

                          Zoning allows you to set up access control between hosts and storage devices. When a zone is configured or the configuration is updated, this information is propagated to all the other switches in the fabric.

                          In Cisco UCS, the zoning configuration is inherited from an upstream switch. You cannot configure zoning or view information about your zoning configuration through Cisco UCS Manager. The only configurable zoning option in Cisco UCS Manager is whether the default zone in a VSAN (nodes not assigned to any zone) permits or denies access among its members.

                          When default zoning is enabled, all traffic is permitted among members of the default zone.

                          When default zoning is disabled, all traffic is denied among members of the default zone.

                          Default zoning is applied on a per-VSAN basis. You cannot enable default zoning at the fabric level.


                          Note


                          Default zoned configurations are not recommended for production deployments, which must always use direct connect Fibre Channel topologies with upstream MDS or Nexus 5000 switches.

                              Uplink Ethernet Port Channels

                              An uplink Ethernet port channel allows you to group several physical uplink Ethernet ports (link aggregation) to create one logical Ethernet link to provide fault-tolerance and high-speed connectivity. In Cisco UCS Manager, you create a port channel first and then add uplink Ethernet ports to the port channel. You can add up to eight uplink Ethernet ports to a port channel.


                              Note


                              Cisco UCS uses Link Aggregation Control Protocol (LACP), not Port Aggregation Protocol (PAgP), to group the uplink Ethernet ports into a port channel. If the ports on the upstream switch are not configured for LACP, the fabric interconnects treat all ports in an uplink Ethernet port channel as individual ports and therefore forward packets.

                                      Appliance Port Channels

                                      An appliance port channel allows you to group several physical appliance ports to create one logical Ethernet storage link for the purpose of providing fault-tolerance and high-speed connectivity. In Cisco UCS Manager, you create a port channel first and then add appliance ports to the port channel. You can add up to eight appliance ports to a port channel.

                                      Configuring an Appliance Port Channel

                                      Procedure
                                          Command or Action Purpose

                                        Enters Ethernet storage fabric mode for the specified fabric.

                                         
                                        Step 3 UCS-A /eth-storage/fabric # create port-channel port-num  

                                        Creates a port channel on the specified Ethernet storage port, and enters Ethernet storage fabric port channel mode.

                                         
                                        Step 4 UCS-A /eth-storage/fabric/port-channel # {enable | disable}   (Optional)

                                        Enables or disables the administrative state of the port channel. The port channel is disabled by default.

                                         
                                        Step 5 UCS-A /eth-storage/fabric/port-channel # set name port-chan-name   (Optional)

                                        Specifies the name for the port channel.

                                         
                                        Step 6 UCS-A /eth-storage/fabric/port-channel # set pingroupname pin-group name   (Optional)

                                        Specifies the appliance pin target to the specified fabric and port, or fabric and port channel.

                                         
                                        Step 7 UCS-A /eth-storage/fabric/port-channel # set portmode {access | trunk}   (Optional)

                                        Specifies whether the port mode is access or trunk. By default, the mode is set to trunk.

                                         
                                        Step 8 UCS-A /eth-storage/fabric/port-channel # set prio sys-class-name   (Optional)

                                        Specifies the QoS class for the appliance port. By default, the priority is set to best-effort.

                                        The sys-class-name argument can be one of the following class keywords:

                                        • Fc—Use this priority for QoS policies that control vHBA traffic only.
                                        • Platinum—Use this priority for QoS policies that control vNIC traffic only.
                                        • Gold—Use this priority for QoS policies that control vNIC traffic only.
                                        • Silver—Use this priority for QoS policies that control vNIC traffic only.
                                        • Bronze—Use this priority for QoS policies that control vNIC traffic only.
                                        • Best Effort—Do not use this priority. It is reserved for the Basic Ethernet traffic lane. If you assign this priority to a QoS policy and configure another system class as CoS 0, Cisco UCS Manager does not default to this system class. It defaults to the priority with CoS 0 for that traffic.
                                         
                                        Step 9 UCS-A /eth-storage/fabric/port-channel # set speed {1gbps | 2gbps | 4gbps | 8gbps | auto}   (Optional)

                                        Specifies the speed for the port channel.

                                         
                                        Step 10 UCS-A /eth-storage/fabric/port-channel # commit-buffer  

                                        Commits the transaction to the system configuration.

                                                Fibre Channel Port Channels

                                                A Fibre Channel port channel allows you to group several physical Fibre Channel ports (link aggregation) to create one logical Fibre Channel link to provide fault-tolerance and high-speed connectivity. In Cisco UCS Manager, you create a port channel first and then add Fibre Channel ports to the port channel.

                                                You can create up to four Fibre Channel port channels in each Cisco UCS domain. Each Fibre Channel port channel can include a maximum of 16 uplink Fibre Channel ports.

                                                Note


                                                If you are connecting two Fibre Channel port channels, the admin speed for both port channels must match for the link to operate. If the admin speed for one or both of the Fibre Channel port channels is set to auto, Cisco UCS adjusts the admin speed automatically.

                                                      Step 2 UCS-A /fc-uplink # scope fabric {a | b }  

                                                      Enters Fibre Channel uplink mode for the specified fabric.

                                                      Enters Fibre Channel uplink port channel mode.

                                                       
                                                      Step 4 UCS-A /fc-uplink/fabric/port-channel # {enable | disable }  

                                                      Enables or disables the administrative state of the port channel. The port channel is disabled by default.

                                                       

                                                      The following example enables port channel 13 on fabric A and commits the transaction:

                                                        Step 4 UCS-A /fc-uplink/fabric/port-channel # create member-port slot-num port-num  

                                                        Creates the specified member port from the port channel and enters Fibre Channel uplink fabric port channel member port mode.

                                                          Adapter Port Channels

                                                          An adapter port channel groups all the physical links from a Cisco UCS Virtual Interface Card (VIC) to an IOM into one logical link.

                                                          Adapter port channels are created and managed internally by Cisco UCS Manager when it detects that the correct hardware is present. Adapter port channels cannot be configured manually. Adapter port channels are viewable using the Cisco UCS Manager GUI or Cisco UCS Manager CLI

                                                            This following example shows how to display information on host port channels within a fabric in the Ethernet server mode:

                                                            UCS-A /eth-server/fabric # 

                                                            Fabric Port Channels

                                                            Fabric port channels allow you to group several of the physical links from an IOM to a fabric interconnect into one logical link for redundancy and bandwidth sharing. As long as one link in the fabric port channel remains active, the fabric port channel continues to operate.

                                                            If the correct hardware is connected, fabric port channels are created by Cisco UCS Manager in the following ways:

                                                            • During chassis discovery according to the settings configured in the chassis discovery policy.
                                                            • After chassis discovery according to the settings configured in the chassis connectivity policy for a specific chassis.

                                                            For each IOM there is a single fabric port channel. Each uplink connecting an IOM to a fabric interconnect can be configured as a discrete link or included in the port channel, but an uplink cannot belong to more than one fabric port channel. For example, if a chassis with two IOMs is discovered and the chassis discovery policy is configured to create fabric port channels, Cisco UCS Manager creates two separate fabric port channels: one for the uplinks connecting IOM-1 and another for the uplinks connecting IOM-2. No other chassis can join these fabric port channels. Similarly, uplinks belonging to the fabric port channel for IOM-1 cannot join the fabric port channel for IOM-2.

                                                            Cabling Considerations for Fabric Port Channels

                                                            When you configure the links between the Cisco UCS 2200 Series IOM and a Cisco UCS 6200 series fabric interconnect in fabric port channel mode, the available VIF namespace on the adapter varies depending on where the IOM uplinks are connected to the fabric interconnect ports.

                                                            Inside the 6248 fabric interconnect there are six sets of eight contiguous ports, with each set of ports managed by a single chip. When uplinks are connected such that all of the uplinks from an IOM are connected to a set of ports managed by a single chip, Cisco UCS Manager maximizes the number of VIFs used in service profiles deployed on the blades in the chassis. If uplink connections from an IOM are distributed across ports managed by separate chips, the VIF count is decreased.

                                                            Caution


                                                            Adding or removing links from a fabric port channel is disruptive and may affect the available amount of VIF namespace.


                                                            For high availability cluster mode applications, symmetric cabling configurations are strongly recommended. If the cabling is asymmetric, the maximum number of VIFs available is the smaller of the two cabling configurations.

                                                            For more information on the maximum number of VIFs for your Cisco UCS environment, see the configuration limits document for your for your hardware and software configuration.

                                                            Procedure
                                                              Step 1   To include all links from the IOM to the fabric interconnect in a fabric port channel during chassis discovery, set the link grouping preference in the chassis discovery policy to port channel.

                                                              Configuring the Chassis Discovery Policy

                                                              Step 2   To include links from individual chassis in a fabric port channel during chassis discovery, set the link grouping preference in the chassis connectivity policy to port channel.

                                                              Configuring a Chassis Connectivity Policy

                                                              Step 3   After chassis discovery, enable or disable additional fabric port channel member ports.

                                                              What to Do Next

                                                              To add or remove chassis links from a fabric port channel after making a change to the chassis discovery policy or the chassis connectivity policy, reacknowledge the chassis. Chassis reacknowledgement is not required to enable or disable chassis member ports from a fabric port channel
