Expected Duplex—Choose the expected duplex of the device that is or will be attached to the
•
Ethernet port. If you know the duplex, choose Full or Half to match the attached device. If you do
not know the duplex, choosing Auto enables autonegotiation for the duplex of the port, and the
CE-100T-8 or CE-MR-6 port will attempt to negotiate a mutually acceptable duplex with the
attached device. If the expected duplex is set to Auto, you cannot enable selective autonegotiation.
Enable Selective Auto Negotiation—Click this check box to enable selective autonegotiation on the
•
Ethernet port. If you do not want to enable selective autonegotiation, uncheck the box. If checked,
the CE-100T-8 or CE-MR-6 port attempts to autonegotiate only to the selected expected speed and
duplex. The link will come up if both the expected speed and duplex of the attached autonegotiating
device matches that of the port. You cannot enable selective autonegotiation if either the expected
speed or expected duplex is set to Auto.
Enable Flow Control—Click this check box to enable flow control on the port (default). If you do
•
not want to enable flow control, uncheck the box. The CE-100T-8 or CE-MR-6 card attempts to
negotiate symmetrical flow control with the attached device.
802.1Q VLAN CoS—For a CoS-tagged frame, the CE-100T-8 or CE-MR-6 card can map the eight
•
priorities specified in CoS for either priority or best effort treatment. Any CoS class higher than the
class specified in CTC is mapped to priority, which is the treatment geared towards low latency. By
default, the CoS is set to 7, which is the highest CoS value. The default results in all traffic being
treated as best effort.
IP ToS—The CE-100T-8 or CE-MR-6 card can also map any of the 256 priorities specified in IP ToS
•
to either priority or best effort treatment. Any ToS class higher than the class specified in CTC is
mapped to priority, which is the treatment geared towards low latency. By default, the ToS is set to
255, which is the highest ToS value. This results in all traffic being sent to the best effort queue by
default.

Untagged traffic is treated as best effort.
If traffic is tagged with both CoS and IP ToS, then the CoS value is used, unless the CoS
value is 7.
Reprovisioning an Ethernet port on the CE-100T-8 or CE-MR-6 card does not reset the Ethernet
statistics for that port.
