Appendix C: Alternative Configuration for Tagged VLANs
The default Cisco HyperFlex installer defines only a single VLAN for virtual machine traffic in the Cisco UCS
configuration. In many cases, multiple VLANs are used to carry guest virtual machine traffic, and the standards set
at the customer data center require that all virtual machine traffic be tagged with the appropriate IEEE 802.1Q
VLAN ID. To accommodate that requirement, you must first make changes in the Cisco UCS configuration. To
modify the Cisco UCS settings to carry multiple tagged VLANs, complete the following steps:
1. In Cisco UCS Manager, click the LAN tab in the navigation pane.
2. Choose LAN > Policies > root > Sub-Organizations > hx-cluster > vNIC-Templates.
3. Click the vNIC template named vm-network-a.
4. In the configuration pane, click Modify VLANs.
5. In the Modify VLANs window, verify that the radio buttons in the Native VLAN column are all cleared.
6. In the Modify VLANs window, click the Select box next to each VLAN that will be tagged and carry guest virtual
machine traffic to the Cisco Nexus 1000V Switch.
7. Click OK.
8. Repeat steps 3 through 7 for the vNIC template named vm-network-b.
Note: This step might not be needed if you are using Cisco HyperFlex HX Data Platform Release 1.8 or later.
