Defining CoS Unicast BA Classifiers
Packet classification associates incoming packets with a particular CoS servicing level. Behavior aggregate (BA) classifiers examine the Differentiated Services code point (DSCP or DSCP IPv6) value or IEEE 802.1p CoS value in the packet header to determine the CoS settings applied to the packet. BA classifiers allow you to set the forwarding class and loss priority of a packet based on the incoming CoS value.
Unicast traffic must use different classifiers than multidestination (mulitcast, broadcast, and destination lookup fail) traffic.
To configure a unicast BA classifier using the CLI:
- Create a unicast BA classifier:
- To create a unicast BA classifier based on the default
classifier, import the default DSCP, DSCP IPv6, or IEEE 802.1p classifier
and associate it with a forwarding class, a loss priority, and a code
point:
[edit class-of-service classifiers]
user@switch# set (dscp | ieee-802.1) classifier-name import default forwarding-class forwarding-class-name loss-priority level code-points [aliases] [bit-patterns] - To create a unicast BA classifier that is not based on
the default classifier, create a DSCP, DSCP IPv6, or IEEE 802.1p classifier
and associate it with a forwarding class, a loss priority, and a code
point:
[edit class-of-service classifiers]
user@switch# set (dscp | ieee-802.1) classifier-name forwarding-class forwarding-class-name loss-priority level code-points [aliases] [bit-patterns]
- To create a unicast BA classifier based on the default
classifier, import the default DSCP, DSCP IPv6, or IEEE 802.1p classifier
and associate it with a forwarding class, a loss priority, and a code
point:
- Apply the unicast classifier to a specific 10-Gigabit
Ethernet interface or to all 10-Gigabit Ethernet interfaces or to
all Fibre Channel interfaces on the switch.
- To apply the classifier to a specific interface:
[edit class-of-service interfaces]
user@switch# set interface-name unit unit classifiers (dscp | ieee-802.1) classifier-name - To apply the classifier to all 10-Gigabit Ethernet interfaces
on the switch, use wildcards for the interface name and the logical-interface
(unit) number:
[edit class-of-service interfaces]
user@switch# set xe-* unit * classifiers (dscp | ieee-802.1) classifier-name
- To apply the classifier to a specific interface:
