5.8.2.3 Trunk Mode
Trunk Mode can be configured in a BSU, SU, End Point A and End Point B. This mode is used to connect VLAN aware
networks with VLAN aware networks. In the Trunk mode, the Ethernet interface of the device forwards only those tagged
frames whose VLAN Id matches with a VLAN Id present in the trunk table.
If the device receives untagged frames and the Allow Untagged Frames functionality is disabled, then the untagged
packets are dropped.
If the Allow Untagged Frames functionality is enabled, then functionality varies based on the device:
·
In case of a BSU, the untagged packets are forwarded to the destination.
·
In case of an SU, End Point A and End Point B, the device behaves as in Access Mode for untagged traffic. The
untagged frames are tagged with the configured Port VLAN ID and forwarded to the destination.
: Mixed VLAN Mode = Trunk Mode + Allow Untagged Frames + Port VLAN ID
To configure the Ethernet interface of the device in Trunk mode, navigate to ADVANCED CONFIGURATION > VLAN >
Ethernet. The VLAN Ethernet Configuration screen appears:
