Chapter 17: Classifier Commands
288 Section II: Advanced Operations
ˆ Number of Active Associations - The number of active ACLs and QoS
policy assignments where the classifier is currently assigned. An
active ACL or policy is assigned to at least one switch port.
You can use this number together with the Number of References to
determine the number of inactive ACLs and policies for a classifier. For
example, if Number of References for a classifier is 4 and the Number
of Active Associations is 3, one of the ACL or QoS policy assignments
for the classifier is not assigned to a switch port.
Examples
This command displays all of the classifiers on the switch:
show classifier
This command displays the details for just classifier ID 12:
show classifier=12
