Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure QoS for Outbound Traffic
Executing this command
displays the current ToS
configuration and shows that the
selected DSCP is not currently in
use.
The 000110 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.
Figure 6-16. Example Showing Codepoints Available for Direct 802.1p Priority
Assignments
Notice that codepoints 000000 and 001001 are named as DSCP
policies by other codepoints (000001 and 000110 respectively). This
means they are not available for changing to a different 802.1p priority.
Outbound IP packets
with a DSCP of 000110
will have a priority of 7.
