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.
Connection Type and Speed
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, the DAC ES self-sets
these options based on the traffic type detected.
Interface Cable Type
Provides selection per port of auto or manual settings for the interface cable type;
Mdi or MdiX (straight or cross-over cable respectively).
Priority
Provides selection per-port of priority options low, medium low, medium high,
and high. This prioritization only has relevance to ports using a shared channel.
Ports with a higher priority will have their data packets accepted by the queue
controller ahead of the lower priority ports on a 8:4:2:1 weighted basis where, for
example, 8 high priority packets will be sent for every one low priority packet.
Port Up
Indicates that valid Ethernet framing has been detected. Unconnected ports or
ports with invalid framing are red-flagged.
Resolved
Indicates the DAC ES has determined the presence of valid Ethernet data from
the locally connected equipment, and where Auto has been selected, for
Duplex-Speed and/or Mdi/MdiX. Where Auto is selected a port is not
traffic-accepting until resolved.
Priority Mapping
Provides selection of queue-controller operation for the following options. This
selection applies to
all ports.
• Port Default allows priority to be set on a per-port basis (priority options low to
high - see Basic Port Settings above). It ignores any 802.1p VLAN priority tags
or IP DiffServ priority values. This selection only has application where two or
more ports share a common channel.
