Service Lan; Service Vlan - Fujitsu PRIMERGY BX900 Configuration Manual

outgoing packets for this VLAN group will leave the Ethernet Connection Blade untagged, and
the native VLAN tag is stripped.

Service LAN

The Service LAN receives tagged packets from the server blade, but the tags are stripped
when they leave the uplink (external port). Incoming untagged packets received at the
uplink/external port are tagged and send to the corresponding downlinks (server blade) as
tagged packets. Incoming tagged packets at uplink/external ports are dropped.

Service VLAN

The Service VLAN receives tagged packets with Service VLAN ID from the server blade, and
forwards them to uplink/external port as tagged packets. Incoming tagged packets with
Service VLAN ID received at the uplink/external port are sent to the corresponding downlinks/
server blade as tagged packets.
Different Service VLANs may share the same Uplink Set. If the port which is member of the
Service VLAN, receives tagged packets with the Service VLAN ID (SVID), those received
tagged packets will be forwarding based on Service VLAN. The Service VLANs with different
VLAN IDs may overlap in internal ports. The Service VLANs with disjoint uplink sets may have
identical SVID. The Service VLAN only defines the internal ports to form a group and it can
define its external connection by combining Uplink Sets.
Note that (VLAN) Port Group and Service (V)LAN may overlap on the internal ports
(downlinks). The untagged packets received from the server blade or uplink ports should obey
the rule of the (VLAN) Port Group.
