DLP- D137 Provision a J1 Path Trace on STM-N Ports
• 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.
Step 4 Click Apply.
Step 5 Refresh the Ethernet statistics:
a. Click the Performance > Ether Ports > Statistics tabs.
b. Click Refresh.
Note Reprovisioning an Ethernet port on the CE-100T-8 card does not reset the Ethernet statistics for
that port.
Step 6 Return to your originating procedure (NTP).
DLP-D137 Provision a J1 Path Trace on STM-N Ports
Purpose This task monitors a path trace on VC4 high-order ports within the circuit
path.
Tools/Equipment The STM-N ports that you want to monitor must be on STM-N cards
capable of receiving path trace. See Table 19-5 on page 19-68 for a list of
applicable cards.
