From the View/Modify Virtual Ethernet view in IVM as shown Figure 4-25 the
four default VIO Server Ethernet adapters are displayed.
Figure 4-25 Default VIO Server virtual Ethernet Adapters shown by IVM
When creating a new virtual Ethernet adapter for the VIO Server we will be
assigning PVIDs and additional VLAN ids. The PVID used should be unique and
not used by any clients in the network or physical Ethernet switch ports. This
requirement is to prevent the unintentional removal or stripping of VLAN tags
from network packets when entering the VIO Server.
The chhwres command is used to created a new VIO Server virtual Ethernet
adapter. Example 4-14 creates a new VIOS adapter with a PVID of 555, with
IEEE 802.1q is enabled and additional VLANS of 20, 30, and 40,
Note: Figure 4-25 shows additional partitions. Partition creation is not covered
until 4.7, “Partition configuration for Virtual I/O Client (VIOC)” on page 144.
