The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
Starting in Release 5.2(1)SP1(7.1), the Cisco Nexus Cloud Services Platform supports only a flexible network uplink configuration to connect to the network. When you perform a new installation of the Cisco Nexus Cloud Services Platform, you cannot choose the network uplink topology. If you are upgrading to Release 5.2(1)SP1(7.1) from an earlier release of the Cisco Nexus Cloud Services Platform, your existing topology will automatically convert to a flexible network uplink topology.
You can use the default network uplink configuration to connect the Cisco Nexus Cloud Services Platform to the network and enable traffic segregation policies such as virtual service blade (VSB) traffic segregation.
The network uplink configuration consists of the following features:
Complete flexibility in terms of port configuration and usage.
Flexible building of ports into a port channel.
Flexible assignment of a port or port channel to a VSB interface.
Easy uplink configuration.
Ability to achieve maximum uplink.
Every physical port individually forms an uplink.
Each uplink can be configured independently.
No default redundancy for uplinks.
Ability to bundle physical ports into a port channel.
VSB traffic is segregated by default.
You can manually configure a VSB interface to share a port.
You can make changes to the default network uplink configuration to suit your needs. However, you must ensure that you do the following when you configure the network uplinks:
Assign the control and management uplinks to an interface. These interfaces can be single or port channel interfaces.
Assign a native VLAN to the port channel interfaces.
You can use physical ports as individual uplinks or you can bundle these uplinks into a port channel. The network uplink configuration is flexible because you can bundle ports into a port channel.
The Cisco Nexus 1110-X has two Peripheral Component Interconnect (PCI) slots that are shipped with the Cisco UCS VIC 1225 10-Gbps Dual-Port NIC (10-Gbps card) and the Intel 1-Gbps quad-port NIC.
Caution | The Cisco Nexus Cloud Services Platform does not boot up if either of the PCI slots fails to detect the appropriate inserted card. For information about the correct slots to insert the cards on the Cisco Nexus Cloud Services Platform, see the Cisco Nexus Cloud Services Platform Hardware Installation Guide. |
If you are upgrading to Release 5.2(1)SP1(7.1) from an earlier release of the Cisco Nexus Cloud Services Platform, the Cisco UCS 10-Gbps Dual-Port NIC is listed as part of the installed hardware. You can then assign uplinks to it or form a port channel with another Cisco UCS 10-Gbps port.
Note | The Cisco UCS 10-Gbps interface card is enabled only for the Cisco Nexus 1110-X model. If the Cisco UCS 10-Gbps card is enabled, it is detected as Ethernet 7 and Ethernet 8 on the Cisco Nexus 1110-X. |
If you are performing a new installation of the Cisco Nexus 1110-X, the Cisco Nexus Cloud Services Platform software detects the Cisco UCS 10-Gbps NIC, prompts you to choose a control or management VLAN to be added to the interface, and provides a choice to configure the interface as a port channel. For more information about the installation procedure, see the Cisco Nexus Cloud Services Platform Software Installation and Upgrade Guide.
Caution | A Cisco UCS 10-Gbps interface can form a port channel only with another Cisco UCS 10-Gbps interface. |
Starting in Release 5.2(1)SP1(7.1), interface names on the Cisco Nexus Cloud Services Platform are changed from Gigabit Ethernet to Ethernet. The Cisco UCS 10-Gbps interfaces are listed under Ethernet 7 and Ethernet 8.
Note | If the Cisco UCS 10-Gbps card is not detected while enabling a VSB on the Cisco Nexus Cloud Services Platform, the appliance goes into shutdown mode. |
Insert the Cisco UCS 10-Gbps card in the appropriate PCI slot on the Cisco Nexus Cloud Services Platform. For details, see the Cisco Nexus Cloud Services Platform Hardware Installation Guide.
Upgrade to Release 5.2(1)SP1(7.1); the software detects the presence of the interface automatically.
You can configure the port channels in the Cisco Nexus Cloud Services Platform in a flexible network uplink configuration.
Log in to the CLI in EXEC mode.
You must group the ports together in either HA or LACP mode.
You must ensure that the ports are not used by any other port channel or by any VSB interface. To delete a port, see Deleting Port Channels.
Know that an Ethernet interface with a conflicting native VLAN cannot be part of an existing port channel.

You can delete port channels. You must first delete ports from the port channel and then delete the port channel.
Command or Action | Purpose |

You can assign uplinks to a VSB interface.
Log in to the CLI in EXEC mode.
Know that:
By default, uplinks are assigned to the first available free port or port channel.
If both free ports and port channels are available, free ports get preference over port channels.
If no free ports are available, you must assign the uplink manually. For information about how to manually assign uplinks to a VSB interface, see Manually Assigning Uplinks to a VSB Interface.
A VSB can have different uplinks for every port or port channel.

You can configure a native VLAN that corresponds to an Ethernet interface. This procedure applies to flexible network uplink types. Native VLAN changes can take effect immediately, except for cases that involve the Cisco Nexus Cloud Services Platform VLANs and interfaces.
Log in to the CLI in EXEC mode.
Know that:
You cannot assign a native VLAN to an Ethernet interface that is a part of a port channel.
You can add an Ethernet interface to a port channel only if the Ethernet interface and the port channel have the same native VLAN configuration.
After you configure the native VLANs in the Cisco Nexus Cloud Services Platform, you must also configure all the upstream switches with the same native VLAN.
When you modify the control or management native VLAN uplink configuration, you must first save the configuration and then shut down the Cisco Nexus Cloud Services Platform. You can change the native VLAN configuration on the uplink switch and then restart the Cisco Nexus Cloud Services Platform.
When you delete an Ethernet interface from a port channel, it retains the native VLAN configuration.

You can configure a Cisco Nexus Virtual Extensible Local Area Network (VXLAN) gateway virtual service blade (VSB) or a Citrix NetScaler 1000V to function as a passthrough interface. The passthrough feature enables a VSB to assign a virtual interface to a dedicated uplink. This uplink can be an Ethernet port on the Cisco Nexus Cloud Services Platform or a port channel. For more information, see Setting Up a Passthrough VSB Interface.
To create a port channel, see Configuring Port Channels.
To assign uplinks to a VSB interface, see Assigning Uplinks to a VSB Interface.
To set up a VSB interface in passthrough mode, see Setting Up a Passthrough VSB Interface.
This section provides the uplinks feature release history.
