50.4.4.2 Forwarding Process Example
Tagged Frames
1
First the SAM1316-22 checks the VLAN ID (VID) of tagged frames or assigns
temporary VIDs to untagged frames (see
2
The SAM1316-22 checks the frame’s source MAC address against the MAC filter.
3
The SAM1316-22 then checks the VID in a frame’s tag against the SVLAN table.
4
The SAM1316-22 notes what the SVLAN table says (that is, the SVLAN tells the
SAM1316-22 whether or not to forward a frame and if the forwarded frames
should have a tag).
5
Frames might be dropped if they are sent to a CPE (customer premises
equipment) DSL device that does not accept tagged frames.
Untagged Frames
1
An untagged frame comes in from the LAN.
2
The SAM1316-22 checks the frame’s source MAC address against the MAC filter.
3
The SAM1316-22 checks the PVID table and assigns a VID and IEEE 802.1Q
priority.
4
The SAM1316-22 ignores the port from which the frame came, because the
SAM1316-22 does not send a frame to the port from which it came. The
SAM1316-22 also does not forward frames to “forbidden” ports.
5
If after looking at the SVLAN, the SAM1316-22 does not have any ports to which it
will send the frame, it drops the frame.
50.4.5 VLAN Frame Type Command
Syntax:
ras> switch vlan frametype <portlist> <all|tag>
where
<portlist>
=
You can specify a single DSL port <1>, all DSL ports
<*> or a list of DSL ports <1,3>. You can also include a
range of DSL ports <1,5,6~8>.
