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:
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.
Configuring Server Ports
ProcedureYou can only configure server ports on the fixed port module. Expansion modules do not include server ports.
This task describes only one method of configuring ports. You can also configure ports from a right-click menu, from the General tab for the port, or in the LAN Uplinks Manager.
Configuring Uplink Ethernet Ports
ProcedureYou can configure uplink Ethernet ports on either the fixed module or an expansion module.
This task describes only one method of configuring uplink Ethernet ports. You can also configure uplink Ethernet ports from a right-click menu or from the General tab for the port.
What to Do Next
If desired, change the properties for the default flow control policy and admin speed of the uplink Ethernet port.
Changing the Properties of an Uplink Ethernet Port
Procedure
Configuring an FCoE Storage Port
You can configure FCoE storage ports on either the fixed module or an expansion module.
This task describes only one method of configuring FCoE storage ports. You can also configure FCoE storage ports from the General tab for the port.

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
At this time, we do not recommend that default zoning be disabled for production deployments.
Enabling Default Zoning
Procedure
Step 1 In the Navigation pane, click the SAN tab. Step 2 In the SAN tab, click the SAN node. Step 3 In the Work pane, click the VSANs tab. Step 4 Click one of the following subtabs, depending upon the type of VSAN for which you want to enable default zoning:

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.
