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.

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
Command or Action Purpose Step 1 UCS-A# scope fc-storage Enters Fibre Channel storage mode.
Step 2 UCS-A /fc-storage # scope vsan vsan-name vsan-id fcoe-id Enters Fibre Channel storage VSAN mode.

The following example enables default zoning for a VSAN called accounting with VSAN ID 2112 and FCoE VSAN ID 4021 and commits the transaction:
UCS-A# scope fc-storage UCS-A /fc-storage # scope vsan accounting 2112 4021 UCS-A /fc-storage/vsan # set default-zoning enabled UCS-A /fc-storage/vsan* # commit-buffer UCS-A /fc-storage/vsan #Disabling Default Zoning
Procedure
Command or Action Purpose Step 1 UCS-A# scope fc-storage Enters Fibre Channel storage mode.
Step 2 UCS-A /fc-storage # scope vsan vsan-name vsan-id fcoe-id Enters Fibre Channel storage VSAN mode.
Step 3 UCS-A /fc-storage/vsan # set default-zoning disabled Disables default zoning.
When default zoning is disabled, all traffic is denied among members of the default zone.
Step 4 UCS-A /fc-storage/vsan # commit-buffer Commits the transaction.
The following example disables default zoning for a VSAN called accounting with VSAN ID 2112 and FCoE VSAN ID 4021 and commits the transaction:
UCS-A# scope fc-storage UCS-A /fc-storage # scope vsan accounting 2112 4021 UCS-A /fc-storage # set default-zoning disabled UCS-A /fc-storage* # commit-buffer UCS-A /fc-storage #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.
