IMPORTANT
When Ethernet Interface is selected or EBEM Network specification is enabled, these
parameters are available.
ETH FLOW CONTROL {Disabled,
Enabled}
Disable or enable flow control.
Only visible when Ethernet is selected as
the interface type.
ETH DAISY CHAIN
{Disabled, Port
4}
Not Available with only one physical port
Disable the Ethernet Port Daisy Chaining or enable it on Port 4.
Only
visible when Ethernet is selected as the interface type.
ETH QOS TYPE
{NORMAL,
PORT BASED}
Selects the priority hierarchy of processing an IEEE 803.3ac Tag, Ipv4
Type of Service Field / Differentiated Services Field, or Ipv6 Traffic
Class Field. The Port Based priority overrides any standard priority.
When operating in this mode, (JS1) has the highest priority and (JS4)
has the lowest.
ETH QOS QUEUE
{FAIR
WEIGHTED,
STRICT
PRIORITY}
Selects the queue weighting of 8, 4, 2, 1 that insures even the lowest
priority traffic gets some bandwidth. Strict Priority insures that the higher
priority traffic will always be transmitted before any lower priority traffic.
With this setting, the lower priority traffic can starve.
ETH CRC ROUTE
{NORMAL,
BYPASS}
Not Available in EBEM Mode
Determines how the modem will route a packet with a bad CRC. In
normal mode, the modem will drop a packet that has an incorrect CRC.
In bypass mode the modem will pass on the packet even with an
incorrect CRC.
ETH HDLC
{RADYNE,
COMTECH,
MANAGED
570}
Not Available in EBEM Mode
Selects Radyne HDLC, Comtech HDLC or Managed 570 Mode.
