[vSRX] How to add SRIOV interface as network adapter



Article ID: KB32411 KB Last Updated: 15 Jan 2018Version: 1.0

According to the document on Adding vSRX Interfaces, SRIOV must be added as PCI adapter on vSRX. However, when attempted have VLAN tagged traffic flow through such PCI adapter SRIOV interface, it did not work. This is because VMware lacks support for VLAN traffic on PCI devices.

According to VMware's document on Network Adapter Types, it needs to be added as SR-IOV passthrough network adapter.

This article explains the procedure for adding SR-IOV as network adapter on vSRX hosted on VMware and supports VLAN tagged traffic to passthrough.

  5.  Right click on the VM and go to Compatibility and select Upgrade VM Compatibility.

  6. Based on the ESXi version, select any one of the two options shown: ESXi 5.5 and later(VM version 10) or ESXi 6.0 and later(VM version 11).

  7. The upgrade would be completed instantly and the new version is displayed:

  8. Click ‚ÄčEdit at the top right. Select New device: Network and Add.

  9. Expand the New Network. From the dropdown for Adapter Type, select SRIOV passthrough.

  10. Select the desired physical function from the dropdown Allow the Guest OS MTU Change.
