1-24 Functional Description IPmux-8/16 Ver. 6.00
Table 1-11. Mode G
Ingress Egress
If a double-tagged frame enters the transparent
port, it is switched to the double-tagged port
• If the double-tagged port is not a member of the first
VID of the frame, the frame is discarded
• If the double-tagged port is a member of the first VID
of the frame, it removes the firs tag and transmits the
frame tagged.
If a tagged frame enters the transparent port, it
is switched to the double-tagged port
• If the double-tagged port is not a member of the
frame VID, the frame is discarded
• If the double-tagged port is a member of the frame
VID, it removes the tag and transmits the frame
untagged
If an untagged frame enters the transparent port,
the frame is discarded
If a tagged frame enters the double-tagged port,
the port adds tag (VID is the double-tagged port
default VID and PRI is the double-tagged port
default PRI), and switches the frame to the
transparent port
The transparent port transmits the frame unmodified
(double tagged)
If an untagged frame enters the double-tagged
port, the port adds tag (VID is the double-tagged
port default VID and PRI is the double-tagged
port default PRI), and switches the frame to the
transparent port
The transparent port transmits the frame unmodified
(tagged)
When operating in the Mode G, the following rules apply:
• No VLANs can be created on the network port.
• Each user port has to be a member of its default VLAN ID, no other VLANs are
valid.
• Both user ports can get the same default VLAN ID.
• In either case, no traffic is allowed between two user ports.
Throughput Limitations and System Usage Control
For IPmux-16 with CT3 modules only.
Every Ethernet interface can handle a limited packet per second (pps) capacity.
This limitation may be reached only when using a CT3 card. IPmux-16 deploys a
System Usage Control mechanism that prevents configurations that will exceed the
pps. This mechanism also monitors and displays current system performance
optimization (percentage of budget in use). If the system usage is 80%, the system
does not allow you to configure another bundle on this Ethernet card.
Ethernet Throughput
TDM bytes per frame (TDM bytes/frame) parameter, per bundle, controls Ethernet
throughput (bandwidth or traffic traveling through the Ethernet). This parameter
defines the number of TDM bytes encapsulated in one frame.
