If ToS Diff-Serv is enabled, executing
this command displays the current ToS
configuration and shows that the
selected DSCP is not currently in use.
The 001100 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.

Outbound IP packets with a
DSCP of 000110 will have a
priority of 7.
Notice that codepoints 000000 and 001001 are named as DSCP policies by
other codepoints ( 000001 and 000100 respectively). This means they are
not available for changing to a different 802.1p priority.
