VLAN Mode supports four separate LANs - each is held separate from the
other. VLAN 1 is the same as for Mixed Mode, where dedicated transport is
provided for port 1 traffic on channel C1. For Ports 2, 3 and 4, the LAN on
each port is transported as a Virtual LAN (VLAN) over a common channel
C2. Internal VLAN tagging of packets ensures correct end-to-end matching
of ports P2 to P4 over the link. The two channels C1 and C2 would normally
be assigned on the same link, but can be used to support separate links.

5. Transport Channel Mode: The options shown in Figure 7-23 are only
supported in SW release 3.6 and later.

Select the mode required:
• No Failure Detection (ES Compatibility) is for use where the DAC GE is
linked to a DAC ES or IDU ES. In this mode the rapid failure detection
(RFD) used to trigger RWPR-enhanced RSTP and layer 2 link aggregation
is disabled.
• Rapid Failure Detection supports RWPR-enhanced RSTP and layer 2 link
aggregation. Select this option where the DAC GE at the far end only
displays a tick-box option for Rapid Transport Channel Failure Detection.
(The far end DAC GE is operating with SW release 3.4 or 3.5).
