Service VLAN networks
Figure 9: Service VLAN networks
The Service VLAN networks are designed to separate LAN packages of mul-
tiple virtual NICs defined in the operating system running on the server blade
and route them to specific uplink (external) ports. To do this, the different vir-
tual NICs in the operating system must be configured to send their packages
with a VLAN tag that is identical to the Service VLAN ID of the Service
VLAN network.
The behavior of a Service VLAN network is such that it receives tagged pack-
ets with the Service VLAN ID from the server blade and forwards them to
uplink ports as tagged packets. The LAN packages leave the IBP tagged at
the uplink ports. Incoming tagged packets with the Service VLAN ID (at the
uplink port) are sent to the corresponding downlink (internal) ports/blade
servers as tagged packets.
