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.
You can configure uplink Ethernet ports on either the fixed module or an expansion module. You can also configure the admin speed as 1Gbps or 10Gbps and assign a flow control policy to the port.
- Uplink Fibre Channel Ports
Uplink Fibre Channel ports handle FCoE traffic between the fabric interconnect and the next layer of the network. All network-bound FCoE traffic is pinned to one of these ports.
You can only configure uplink Fibre Channel ports on an expansion module. The fixed module does not include uplink Fibre Channel ports.

ProcedureUplink Ethernet Ports
Configuring an Uplink Ethernet Port
ProcedureYou can configure uplink Ethernet ports on either the fixed module or an expansion module. You can also configure the admin speed as 1Gbps or 10Gbps and assign a flow control policy to the port.
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 #Deleting an Uplink Ethernet Port
ProcedureUplink 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 for the purpose of providing 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.
NoteCisco UCS uses Link Aggregation Control Protocol (LACP), not Port Aggregation Protocol (PAgP), to group the uplink Ethernet ports into a port channel.

Configuring an Uplink Ethernet Port Channel
ProcedureThe following example creates a port channel on port 13 of fabric A, sets the name to portchan13a, enables the administrative state, assigns the flow control policy named flow-con-pol432 to the port channel, and commits the transaction:
UCS-A# scope eth-uplink UCS-A /eth-uplink # scope fabric a UCS-A /eth-uplink/fabric # create port-channel 13 UCS-A /eth-uplink/fabric/port-channel* # enable UCS-A /eth-uplink/fabric/port-channel* # set name portchan13a UCS-A /eth-uplink/fabric/port-channel* # set flow-control-policy flow-con-pol432 UCS-A /eth-uplink/fabric/port-channel* # commit-buffer UCS-A /eth-uplink/fabric/port-channel #Deleting an Uplink Ethernet Port Channel
ProcedureAdding a Member Port to an Uplink Ethernet Port Channel
ProcedureThe following example adds the member port on slot 1, port 7 to the port channel on port 13 of fabric A and commits the transaction.
UCS-A# scope eth-uplink UCS-A /eth-uplink # scope fabric a UCS-A /eth-uplink/fabric # scope port-channel 13 UCS-A /eth-uplink/fabric # create member-port 1 7 UCS-A /eth-uplink/fabric/port-channel* # commit-buffer UCS-A /eth-uplink/fabric/port-channel #Deleting a Member Port from an Uplink Ethernet Port Channel
ProcedureThe following example deletes a member port from the port channel on port 13 of fabric A and commits the transaction:
UCS-A# scope eth-uplink UCS-A /eth-uplink # scope fabric a UCS-A /eth-uplink/fabric # scope port-channel 13 UCS-A /eth-uplink/fabric/port-channel # delete member-port 1 7 UCS-A /eth-uplink/fabric/port-channel* # commit-buffer UCS-A /eth-uplink/fabric/port-channel #
