In single-tagging mode:
The (inner)VLAN tag is checked and compared to the VLAN ID list configured in
this field for the specific port.
If a port is membership of a specific VLAN ID, frames tagged with this VLAN ID
(single Tagging) or only outerVLAN ID (double tagging) can leave the switch on this
specific port.
egress VID remarking: (only double-tagging mode)
This function affects only outgoing traffic
remove means removing the inner/outer VLAN tag
normalized is sending the frames with inner/outer VLAN tag
as received is sending the frames as the frames came into the current switch. For
example:
Both egress VID remarking are set to as received
The frame comes into switch 1 on port 3 (S1-P3) and has no outerVLAN-Tag but
already an innerVLAN tag and should leave the Switch on port 8 (S1-P8). In this
case the following will happen:
- The frame gets the default VLAN id from port S1-P3 but only the outerVLAN-
tag, the innerVLAN tag is already there.
- VLAN-membership of S1-P8 has the same VLAN ID configured as the default
VLAN-ID on S1-P3. => Frame will leave here the Switch 1
- The frame will be sent from Switch 1 to Switch 2 with innerVLAN tag, because
the frame had already the innerVLAN tag while entering the Switch 1
- The frame will be sent from Switch 1 to Switch 2 without outerVLAN tag,
because the frame had no outerVLAN tag while entering the Switch 1
Note: Please be aware, that the internal ports P4/P8 between the switches must be
handled the same as all other ports. That means: if you want to send data from one
switch to the other, you have to be aware about the egress VID remarking, especially
for the outerVLAN tag if you need this tag in the next switch!
If frames leave on S1-P8 the switch, VLAN tags will be removed or not, dependent
from the configuration of the egress VID remarking. They enter on S2-P4 the next
switch and will be tagged following the tagging rules for incoming traffic
3.7 CAN Gateway
Note: The CAN Gateway is in the Microcontroller (CPU). The Switch 1 has to be
configured in a way that the microcontroller has still a connection to your PC.
Note: The CAN Gateway is not able to work with CAN-FD.
