3 Transport Channel Mode supports selection of the fast-link detection
mechanism used to enable RWPR-enhanced RSTP and layer 2 link
aggregation.
• Rapid Failure Detection and Protection should be selected when there is a
DAC GE at both ends. Both DAC GEs must be with SW release 3.6 or later.
• No Failure Detection (ES Compatibility) is for use where the DAC GE is
linked to a DAC ES or IDU ES.
• Rapid Failure Detection is only required when the far end DAC GE is
operating with SW release 3.4 or 3.5.
4 Ethernet Ports - Basic Setting:
• Ports. The four DAC ES ports P1 to P4 are individually configurable.
• Type. Ports P1 to P3 are fixed as Electrical. Port P4 as optical.
• Enabled. Click to enable required ports. A port must be enabled to allow
traffic flow.
• Name. Each port can be named/identified. Optional.
• Duplex-Speed. Select auto-detect or a specific connection type from the
drop-down menu.
• MdiX. Select auto-detect or a specific cable type from the drop-down menu.
• Priority. Select the required port priority from the drop-down menu.
• Port Up. An arrow indicates detection of valid Ethernet framing at the local
port connection. Unconnected ports or ports with invalid framing are
red-flagged.
• Resolved. Tick indicates the presence of valid Ethernet data from the locally
connected equipment and that auto-negotiation has resolved port connection
status where Auto has been selected.
5 Click to enable flow control (full duplex connections only).
6 Click Disable if the DAC GE is used in a ring/mesh network where protection
is provided by an external RSTP switch.
7 Set the maximum frame size. Setable range is 64 to 9600 bytes.
8 Click to enable link status propagation. Used to shut down a port upon a
channel failure event. Applies where the connected equipment uses port status
to determine the availability of an Ethernet connection.
