Configuring Ports

Contents

Configuring Ports

This chapter includes the following sections:

Server and Uplink Ports on the Fabric Interconnect

Each 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 instance 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.

Each fabric interconnect can include the following types of ports:

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:
  • Server
  • 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 a 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.

Server Ports

Configuring a Server Port

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

          Appliance Ports

          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* # create eth-target macname
              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
              UCS-A /eth-storage* # scope fabric b
              UCS-A /eth-storage/fabric* # scope port-channel 13
              UCS-A /eth-storage/fabric/port-channel* # create eth-target macname
              UCS-A /eth-storage/fabric/port-channel* # set mac-address 01:23:45:67:89:ab
              UCS-A /eth-storage/fabric/port-channel* # commit-buffer

                      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.


                      Enabling Default Zoning

                      Procedure

                          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.


                          Configuring an Uplink Ethernet Port Channel

                          Procedure

                            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 # create port-channel port-num  

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

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

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

                                  Appliance Port Channels

                                  An appliance port channel allows you to group several physical appliance ports (link aggregation) 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.


                                  Note


                                  Cisco UCS uses static mode, not Link Aggregation Control Protocol (LACP), to group the appliance ports into a port channel.

                                    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.

                                            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 instance. 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.
