Figure 6: Networks with a VLAN ID and a native VLAN ID

In the figure above, the VLAN ID 10 is defined as the native VLAN ID in the
upper shared uplink set. As a result, the data packets of server blade 1 with
the VLAN ID 10 (red) exit the uplink without a VLAN ID tag. Incoming data
packets without a VLAN ID tag are assigned the VLAN ID 10 internally.
These data packets are only transferred to server blade 1.

Virtual networks with VLAN ID used in tagged mode

While normally the VLAN IDs of packets that leave the IBP on the server
blade side are removed, it is possible to use a VLAN network in tagged
mode. This means that all packets retain their VLAN tag when they are trans-
mitted to the server blade. Packets that arrive on the server blade side of the
IBP must have a VLAN tag with the corresponding VLAN ID if they are to
transferred to this VLAN network in tagged mode.

Packets without a VLAN tag are dropped unless there is a VLAN network in
untagged mode associated with the same downlink.
