MSAP2000 AAMS User's Guide
3 The MSAP2000 AAMS notes what the SVLAN table says (that is, the SVLAN
tells the MSAP2000 AAMS whether or not to forward a frame and if the
forwarded frames should have a tag).
4 Then the MSAP2000 AAMS applies the port filter to finish the forwarding
decision. This means that frames may be dropped even if the SVLAN says
to forward them. Frames might also be dropped if they are sent to a CPE
(customer premises equipment) DSL device that does not accept tagged
frames.
27.8.7.2.2 Untagged Frames
1 An untagged frame comes in from the LAN.
2 The MSAP2000 AAMS checks the PVID table and assigns a temporary VID.
3 The MSAP2000 AAMS ignores the port from which the frame came,
because the MSAP2000 AAMS does not send a frame to the port from which
it came. The MSAP2000 AAMS also does not forward frames to
"forbidden" ports.
4 If after looking at the SVLAN, the MSAP2000 AAMS does not have any
ports to which it will send the frame, it won't check the port filter.
27.8.8 VLAN Frame Type Command
Syntax:
switch vlan frametype <portlist> <all|tag|untag>
where
<portlist>
<all|tag|untag>
incoming
This command sets the specified DSL ports to accept VLAN tagged Ethernet frames,
untagged
Ethernet frames or both.
Note: The MSAP2000 AAMS accepts both tagged and untagged incoming
frames on the Ethernet ports.
The following example sets the MSAP2000 AAMS to accept only VLAN tagged
Ethernet frames on DSL
port 3.
=
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 <1,5,6~10>.
=
Use tag to have the specified port(s) accept only
Ethernet frames that have a VLAN tag.
Use untag to have the specified port(s) accept only
incoming
Ethernet frames that do not have a VLAN tag.
Use all to have the specified port(s) accept both
tagged and untagged incoming Ethernet frames.
