You can configure ToS/DSCP from the network rules page or the
Class of Service page. Define how the Layer 3 ToS/DSCP will be marked:
-
Go to .
Or, ToS/DSCP and skip to step 5.
-
Select Bandwidth Limit and click
.
-
Click Edit next to Advanced Settings.
-
Click Configure ToS/DSCP.
-
In the ToS/DSCP dialog
box, select either Type of Service (ToS) or Diffserv Codepoint
(DSCP). Set the related options, and click OK.
Type of Service
(ToS)
- Precedence
- Assign a priority to
the packet. Packets with lower priority numbers are more likely to
be discarded by congested routers than packets with higher priority
numbers.
- Delay Sensitive
- Specifies that the
high priority packets will be routed with minimal delay. It can be
useful to enable this option for voice protocols.
- High Throughput
- Specifies that high
priority packets will be routed with high throughput.
- High Reliability
- Specifies that high
priority packets will be routed with low drop probability.
- Explicit Congestion Notification (ECN)
- Permits end-to-end
notification of network congestion while preventing dropped packets.
ECN can be used only with two ECN-enabled endpoints.
Diffserv Codepoint
(DSCP)
- Well-Known Value
- These values are
explicitly defined in the DSCP related RFCs and implemented on many
vendors' switches and routers.
- Raw Binary Value
- Specify a binary
value if you want finer definition of priority.
