3 Configure the following parameters:
Name Naming should reflect the priority for your organization and be easily recognized by your IT team,
such as Bulk Data or Critical Data.
Priority Define how the Layer 2 priority of the packet will be marked. Priority 0 is the highest priority.
4 For
ToS/DSCP
, define how the Layer 3 ToS/DSCP will be marked. Enter a hexadecimal value in the
0x (DSCP:)
field, or select
Configure
to open the ToS/DSCP dialog box.
5 In the CoS dialog box, set the
Mask
value.
Mask Select a hexadecimal value to use for the ToS/DSCP value. For example, if the mask is 0xF0, then only
the four most significant bits of the ToS of the received packets are marked. So, if the received ToS is
0x33 and the ToS marking is set to 0x2A, then the resulting ToS is 0x23.

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.
