Chapter 2. Eclipse Edge System Description
VLAN mode supports two separate LAN connections. Ports 1 and 2 are multiplexed
to C1 to provide two virtual LANs (VLANs 1 and 2). Internal VLAN port tagging of
frames provides correct end-to-end matching of port traffic over the link. Tags are
removed before port egress at the far end.

VLAN Mode Port and Channel Assignment
Transport Channel Configuration
Selection is provided for channel capacity on a per-channel basis.
• Channel capacity is selected in multiples of 2 Mbps.
• The channel supports a maximum 32 Mbps.
Basic Port Settings
Customer selection/confirmation is provided for the following port parameters:
Enabled
A port must be enabled to allow traffic flow.
Name
A port name or other relevant port data can be entered.
Speed-Duplex
Provides selection per-port of auto or manual settings for half or full duplex
operation on speeds of 10 Mbps or 100 Mbps. In auto, a connection is set based on
the traffic type detected.
Interface Type
Provides selection per port of auto or manual settings for the interface type; Mdi or
MdiX (straight or cross-over respectively).
Port Up
Indicates that a valid Ethernet connection with valid Ethernet framing has been
detected.
Resolved
Indicates a port connection has been resolved for an auto speed-duplex setting.
Priority Mapping
Port and traffic prioritization is determined using priority options of low, medium
low, medium high, and high. Prioritization is 8:4:2:1 weighted where, for example, 8
high priority packets are sent for every one low priority packet. This ensures that even
low priority traffic gets some bandwidth when link capacity is over-subscribed.
