When configuring VLANs, use the following naming format, which includes both the VID and the physical PPA:
VLAN logical PPA = 1000 * VID + Device-PPA
For example, if the virtual ID is 123 and the device PPA is 2, the VLAN interface would be igb123002. In another example, on a server with an adapter that has an instance number of 2, belonging to two VLANs with VID 123 and VID 224, the VLAN interfaces would be igb123002 and igb224002, respectively.
This format limits the maximum number of PPAs (instances) that can be configured in the /etc/path_to_inst file to 1000.
