Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
Figure 5-11. Example Showing Codepoints Available for Direct 802.1p Priority Assignments
Figure 5-12. Example of a Type-of-Service Configuration Enabling Both Direct 802.1p Priority Assignment
and DSCP Policy Assignment
ProCurve(config)# show qos type-of-service
Type of Service : Differentiated Services
Codepoint DSCP Policy | Priority
--------- ----------- + -----------
000000 | No-override
000001 | No-override
000010 | No-override
000011 | No-override
000100 | No-override
000101 | No-override
000110 | No-override
000111 | No-override
001000 | No-override
001001 | No-override
Executing this command
displays the current ToS
configuration and shows that the
selected DSCP is not currently in
use.
The 001000 codepoint is unused,
and thus available for directly
assigning an 802.1p priority
without changing the packet’s
DSCP.
Note: All codepoints without a
“DSCP Policy” entry are
available for direct 802.1p priority
assignment.

Type of Service : Differentiated Services
Codepoint DSCP Policy | Priority
--------- ----------- + -----------
000000 | No-override
000001 | No-override
000010 | No-override
000011 | No-override
000100 | No-override
000101 16 | No-override
000110 | No-override
000111 15 | No-override
001000 11 | 7
001001 | No-override
Outbound IP packets
with a DSCP of 001000
will have a priority of 7.
