Glossary
Furthermore, the contents of the packet must be consistent with any additional
rule set up for the connection. For example, the VLAN ID in the packet’s VLAN
tag, if any, must be consistent with the tag definition for the potential ingress
connection. If the packet content is not consistent with any of the ingress
connections leading from the port, the packet is discarded.
Likewise, when a packet arrives at a switching domain object, there must be a
proper egress connection before the packet is switched out on an egress port.
Otherwise, the packet is discarded at the switching domain.
7.1 Connection Configuration Example
The following example has five connections:


­
Ingress connection from port 2 to switching domain 2. Only untagged
packets. (“tag = untagged”)


­
Ingress connection from port 2 to switching domain 3. Only tagged
with VLAN ID 2, 3 or 4. (“tag = 2, 3 or 4”)


­
Egress connection from switching domain 2 to port 5. Tagged with
VLAN ID 22. (“tag = 22”)


­
Egress connection from switching domain 3 to port 7. Transparent
VLAN ID. (“tag = transparent”) Destination address A.


­
Egress connection from switching domain 3 to port 9. Transparent
VLAN ID. (“tag = transparent”) Destination address B.
