Bias-Free Language

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 page details the requirements for Nexus 1000V support with Unified CCE. This reference design is based on a UCS B-Series. Designs are not provided for a UCS C-Series or a Specs-based deployment. Adapting this reference design for those platforms might require differences from what is shown here. But, in all cases, provide visible and private network path diversity on the uplinks through either subgroup ID pinning or mac-pinning relative.

Figure1 illustrates a design for Unified CCE on UCS B-Series blades that uses the Nexus 1000v and an Active/Active VMNIC design:

To maintain route diversity for the public and private networks, the Nexus 1000v requires use of either subgroup ID pinning or mac-pinning relative for Unified CCE uplinks. The following steps demonstrate how to pin the public and private networks to separate physical interfaces for a sample Nexus 1000v configuration:

Configure the Unified CCE Ethernet port profiles as port channels that use CDP or manually created subgroup IDs or mac-pinning relative, as described in the chapter on configuring port channels of the Cisco Nexus 1000V for VMware vSphere Interface Configuration Guide.
NOTE: Do not use the Unified CCE uplinks for host management or any other third party applications. Configure more uplinks for management traffic.
Use the module vem module_number execute vemcmd show pinning command on the Nexus 1000v VSM to identify the virtual supervisor module sub group ID (VSM_SGID) for use in the Nexus 1000v vEthernet port profile configuration.
The following is sample output from the Nexus 1000v VSM, for a VEM on the Unified CCE A Side data center:

53 1c0004b0 305   3 3 0 uccepg121b ethernet2
Identify the virtual supervisor module sub group IDs (VSM_SGID) as shown in the example above. Then, use these IDs in the vEthernet port profiles for the public and private network interfaces.
Configure the Unified CCE public vEthernet port profile:

---For subgroup ID pinning, configure the public profile with one of the Sub Group IDs. Then configure the private profile with the remaining Sub Group ID.
---For mac-pinning relative, configure the public profile with a primary and backup Sub Group ID. Then configure the private profile with an alternate primary and backup Sub Group ID.

For details about any of the configurations, see the Nexus 1000v documentation.

4. Configure QOS to match the DSCP values from the Unified CCE applications and mark them with COS values. These values enable the Fabric Interconnects and upstream L2 switches to prioritize traffic appropriately within the data center.

To configure Unified CCE with the Nexus 1000v when QOS for the Visible Network is not enabled, use high priority addressing for the Router and the Peripheral Gateway. See the Cisco Unified Contact Center Enterprise Installation and Upgrade Guide and the sample Unified CCE Nexus 1000v QOS Configuration example below, specifically the italicized print.

NOTES:

All servers using relative pinning must have a common vNIC visible/private binding order. This ensures that across all servers hosting Unified CCE components the visible network and private network will be pinned to separate physical upstream switches.
The QOS configuration examples vary from the standard UC and CC practice where CS3 and AF31 map to COS 3. Because this reference design is for a UCS B-Series deployment, where Fibre Channel defaults to COS 3, map those DSCP values to COS 4 or 5 (for better performance and differentiation within the data center fabric).
Setting dscp in the Nexus 1000v is optional, and whether you set dscp there or not, you still need QoS prioritization configuration at the WAN edge as described in the Cisco Unified Contact Center Enterprise Design Guide.See the section on bandwidth provisioning and QoS considerations in the guide.
Deploy the Nexus 1000v VSM for high availability on separate infrastructure. Do not deploy the Nexus 1000v VSM coresident with UC/CC applications.
The Cisco Virtual Interface Cards are the only supported adapters when deploying the Nexus 1000v with Unified CCE.
