Configuring a Global MPLS EXP Classifier
EXP packet classification associates incoming packets with a particular MPLS CoS servicing level. EXP behavior aggregate (BA) classifiers examine the MPLS EXP value in the packet header to determine the CoS settings applied to the packet. EXP BA classifiers allow you to set the forwarding class and loss priority of an MPLS packet based on the incoming CoS value.
You can configure up to 64 EXP classifiers, however, the switch
uses only one MPLS EXP classifier as a global classifier, which is
applied only on interfaces configured as family mpls. All family mpls switch interfaces use the global EXP classifier
to classify MPLS traffic.
There
is no default EXP classifier. If you want to classify incoming MPLS
packets using the EXP bits, you must configure a global EXP classifier.
The global classifier applies to all MPLS traffic on all family
mpls interfaces.
If
a global EXP classifier is configured, MPLS traffic on family
mpls interfaces uses the EXP classifier. If a global EXP classifier
is not configured, then if a fixed classifier is applied to the interface,
the MPLS traffic uses the fixed classifier. If no EXP classifier and
no fixed classifier is applied to the interface, MPLS traffic is treated
as best-effort traffic. DSCP classifiers are not applied to MPLS traffic.
To configure an MPLS EXP classifier using the CLI:
