DLP- A513 Provision CE-100T-8 Ethernet Ports
•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 attempts to negotiate symmetrical
flow control with the attached device.
•802.1Q VLAN CoS—For a class-of-service (CoS)-tagged frame, the CE-100T-8 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 can also map any of the 256 priorities specified in IP type-of-service (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.
Note Untagged traffic is treated as best effort.
Note If traffic is tagged with both CoS and IP ToS, then the CoS value is used, unless the CoS
value is 7.
Step4 Click Apply.
Step5 Refresh the Ethernet statistics:
a. Click the Performance > Ether Ports > Statistics tabs.

Note Reprovisioning an Ethernet port on the CE-100T-8 card does not reset the Ethernet statistics for
that port.
Step6 Return to your originating procedure (NTP).
