Modifying Ethernet SR-IOV Virtual Functions

The ldm set-io vf-name command modifies the current configuration of a virtual function by changing the property values or by setting new properties. This command can modify both the network-specific properties and the device-specific properties. For information about device-specific properties, see Advanced SR-IOV Topics: Ethernet SR-IOV.

If you cannot use this dynamic method, use the static method instead. See Static SR-IOV.

You can use the ldm set-io command to modify the following properties:

  • mac-addr, alt-mac-addrs, and mtu

    To change these virtual function properties, stop the domain that owns the virtual function, use the ldm set-io command to change the property values, and start the domain.

  • pvid and vid

    You can dynamically change these properties while the virtual functions are assigned to a domain. Note that doing so might result in a change to the network traffic of an active virtual function; setting the pvid property enables a transparent VLAN. Setting the vid property to specify VLAN IDs permits VLAN traffic to those specified VLANs.

  • Device-specific properties

    Use the ldm list-io -d pf-name command to view the list of valid device-specific properties. You can modify these properties for both the physical function and the virtual function. You must use the static method to modify device-specific properties. See Static SR-IOV. For more information about device-specific properties, see Advanced SR-IOV Topics: Ethernet SR-IOV.
