Before being transmitted to the port the Ethernet frames are untagged by
the XSLAN.
”Trunk” port
An Ethernet port must be set up as a “Trunk” port, when that port is used
to connect an SHDSL network to another network like an optical network
for instance.
All tagged Ethernet frames entering the port are transmitted towards the
SHDSL network or other ports.
Untagged Ethernet frames are tagged by the XSLAN with the right VLAN
ID code.
Reciprocally, all tagged Ethernet frames coming from the SHDSL network
are transmitted to that port. They are not untagged by the XSLAN.
Untagged Ethernet frames are tagged by the XSLAN with the right VLAN
ID code.
“Tag” port
An Ethernet port must be set up as a “Tag” port, when the device
connected to that port tags the Ethernet frames by itself.
Ethernet frames entering the port are transmitted towards the SHDSL
network or other ports only if they are tagged with one of the four VLAN ID
codes registered by the XSLAN.
Reciprocally, Ethernet frames coming from the SHDSL network or from
other ports of the XSLAN can be transmitted to the port only if they are
tagged with the right VLAN ID code.
They are not untagged by the XSLAN.
“All access” port
Don’t use that value
