White Paper

After the migration is complete, you can delete the original standard vSwitches (named vswitch-hx-vm-network

and vmotion) for the guest virtual machine traffic and vMotion from the Cisco HyperFlex hosts. To delete the

unused standard vSwitches, complete the following steps:

1. In the vCenter web client, select Hosts and Clusters.

2. Click the first Cisco HyperFlex platform ESXi host in the navigation tree.

3. In the right pane, click the Manage tab, click Networking, and choose the Virtual Switches menu item.

4. Click the standard vSwitch named vswitch-hx-vm-network in the list. Then click the Remove Selected

Standard Switch icon.

5. Click Yes to remove the switch.

6. Repeat steps 3 through 5 for the vSwitch named vmotion.

7. Repeat steps 2 through 6 for the remaining hosts in the Cisco HyperFlex cluster.

vCenter will display numerous alarms that were generated during the virtual machine guest switch migration

process. You can safely clear these alarms.

Conclusion

This Cisco solution addresses the needs of many enterprise data centers by allowing the use of VMware

Distributed Virtual Switches in Cisco HyperFlex clusters, staying aligned with established practices. By employing

this solution, you can enable your Cisco HyperFlex system to take advantage of the features offered by vDS and

remain fully supported by the Cisco Technical Assistance Center (TAC).

Appendix A: Configuring Additional Virtual Machine Guest VLANs

In many cases, the Cisco HyperFlex System requires configuration of multiple VLAN IDs for the guest virtual

machines to use for communication. If additional VLANs are required, you must define the VLANs in Cisco UCS

Manager before you can added them to vNIC templates, and they must be configured as part of the ESXi host

networking port groups. To configure additional VLANs for guest virtual machine traffic, complete the following

steps:

1. In Cisco UCS Manager, click the LAN tab in the navigation pane.

2. Choose LAN > LAN Cloud > VLANs.

3. Right-click VLANs and choose Create VLANs.

4. Enter the name of the VLAN.

5. Select the multicast policy named HyperFlex.

6. Leave the setting for Common/Global.

7. Enter the VLAN ID number.
