Description
Using traffic-priority command, you can activate ACL and tag the traffic priority
(whose action is permit). Using undo traffic-priority command, you can cancel the
traffic priority settings.
It can mark three priorities (dscp/IP preference, and cos) for the packets. The switch
can put the packets into egress queue according to the cos value (namely the 802.1p
preference) or local preference. If both 802.1p preference and local preference are set,
the switch will use the 802.1p preference first.
For the related command, see display qos-global traffic-priority.
Example
# Marks the priority for the packets matching the permit rules of ACL 2000. It sets the
local preference to 0:
[Quidway] traffic-priority ip-group 2000 local-precedence 0
