This chapter includes the following sections:
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 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 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.
You can configure uplink Ethernet ports on either the fixed module or an expansion module.
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
You can only configure server ports on the fixed port module. Expansion modules do not include server ports.
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 #
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
You can configure uplink Ethernet ports on either the fixed module or an expansion module.
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 #

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. |
Command or Action | Purpose | |

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. |

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. |

Step 1 | UCS-A# scope fc-uplink | Enters Fibre Channel uplink mode. |
Step 2 | UCS-A /fc-uplink # scope fabric {a | b } | Enters Fibre Channel uplink mode for the specified fabric. |
Step 3 | UCS-A /fc-uplink/fabric # scope port-channel port-chan-name | 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:
UCS-A# scope fc-uplink UCS-A /fc-uplink # scope fabric a UCS-A /fc-uplink/fabric # scope port-channel 13 UCS-A /fc-uplink/fabric/port-channel* # enable UCS-A /fc-uplink/fabric/port-channel* # commit-buffer UCS-A /fc-uplink/fabric/port-channel #
Command or Action | Purpose | |
---|---|---|
Step 1 | UCS-A# scope fc-uplink | Enters Fibre Channel uplink mode. |
Step 2 | UCS-A /fc-uplink # scope fabric {a | b } | Enters Fibre Channel uplink fabric mode for the specified fabric. |
Step 3 | UCS-A /fc-uplink/fabric # scope port-channel port-num | Enters Fibre Channel uplink fabric port channel mode for the specified port channel. |
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. |
Step 5 | UCS-A /fc-uplink/fabric/port-channel # commit-buffer | Commits the transaction to the system configuration. |
The following example adds the member port on slot 1, port 7 to port channel 13 on fabric A and commits the transaction.
UCS-A# scope fc-uplink UCS-A /fc-uplink # scope fabric a UCS-A /fc-uplink/fabric # scope port-channel 13 UCS-A /fc-uplink/fabric # create member-port 1 7 UCS-A /fc-uplink/fabric/port-channel* # commit-buffer UCS-A /fc-uplink/fabric/port-channel #
Command or Action | Purpose | |
---|---|---|
Step 1 | UCS-A# scope fc-uplink | Enters Fibre Channel uplink mode. |
Step 2 | UCS-A /fc-uplink # scope fabric {a | b} | Enters Fibre Channel uplink fabric mode for the specified fabric. |
Step 3 | UCS-A /fc-uplink/fabric # scope port-channel port-num | Enters Fibre Channel uplink fabric port channel mode for the specified port channel. |
Step 4 | UCS-A /fc-uplink/fabric/port-channel # delete member-port slot-num port-num | Deletes the specified member port from the port channel. |
Step 5 | UCS-A /fc-uplink/fabric/port-channel # commit-buffer | Commits the transaction to the system configuration. |
The following example deletes a member port from port channel 13 on fabric A and commits the transaction:
UCS-A# scope fc-uplink UCS-A /fc-uplink # scope fabric a UCS-A /fc-uplink/fabric # scope port-channel 13 UCS-A /fc-uplink/fabric # delete member-port 1 7 UCS-A /fc-uplink/fabric/port-channel* # commit-buffer UCS-A /fc-uplink/fabric/port-channel #
