Configuring traffic priority levels is accomplished using 3Com Central Configuration
Manager:
1. Open 3Com
Central Configuration Manager
and select
Devices
from the main
menu.
2. From the list of devices, select an NJ200 Network Jack and then select
Property
.
You can also right-click on its IP address and select
Property
from the menu.
3. Click on the
Priority
tab and select a PAN (device) port to configure. For example,
the configuration window for Port 2 will look similar to this:
10
4. Under
Priority Lookup Scheme
, choose one of the following settings:
a) None
b) 802.1p Traffic Class fields
c)
Use IP TOS, Diffserv fields
d) Both
To ignore the priority tags on incoming Ethernet frames, set the
Priority Look up
Scheme
to
None
.
Note:
Priority Lookup Scheme specifically instructs the NJ200/NJ205 to inspect Ethernet frames at the LAN
port for 802.1p, Diffserv, or both. If the incoming traffic will not be Diffserv or 802.1p, the Priority Lookup
Scheme should be set at “None.”
5. Under
Default Priority Level
, set what priority level to associate with the PAN port:
a) 802.1p Priority 0 or 1
b) 802.1p Priority 2 or 3
c)
802.1p Priority 4 or 5
d) 802.1p Priority 6 or 7
6. Click
OK
to exit the configuration window. Repeat these steps for the other PAN ports.
Figure 7.
Traffic priority levels are individually
configured for each PAN port.
