ip classifier
Creates/deletes an IP classifier to group IP traffic into classes.
Syntax: ip classifier name psc ipPsc_value
no ip classifier name
name
The name of the IP classifier group.
ipPsc_value
One or more PSC values to be associated with this classifier group. Supported values are from 0 to 3. A range of consecutive values is delineated by a dash (-). Nonconsecutive values are delineated by a comma (,). Default: None.
Description: Classifiers provide a convenient means of grouping traffic into classes. Traffic belonging to the same class is treated equally. IPriori supports the classification of data by Per-hop Scheduling Class (PSC). Classifiers are configured at the global level and do not have actual interface resources associated with them until you establish a traffic assignment using the qos command, at which time one or more classifiers will be associated with a packet treatment.
A classifier can contain one or more PSC values. A single group can be entered per command line. An IP classifier's name can not be the same as any MPLS classifier's name. Each multiple value entry must be delineated based upon whether it is part of a consecutive range or nonconsecutive set. A range of consecutive values is delineated by a dash (-); e.g., values 1 through 3 are entered as 1-3. A nonconsecutive set of values is delineated by a comma (,); e.g., values 1 and 3 are entered as 1,3.
You can configure as many IP classifiers as you wish. A configured classifier can contain any combination of valid PSC values. When assigning multiple classifiers to a single interface using traffic assignments, the traffic classes of one classifier can not be a proper subset of another classifier, i.e. no IP classifier can have a proper subset member of another IP classifier.
For example, if one IP classifier has values 1-3 as its members, another IP classifier assigned to the same interface can not have values 2,3 as its members. This is true whether you are configuring multiple IP classifiers to a single traffic assignment or configuring multiple traffic assignments to an interface. An error will be generated if a proper subset of one group is found in a second group for a single interface.
Use the ip classifier name psc ipPsc_value command to create an IP classifier group with the specified PSC value.
Use the no ip classifier name command to delete a named classifier group.
Factory Default: None.
Command Mode: Configuration.
Example 1: The following command creates an IP classifier named cIP1 and associates PSC values 0 and 1 with it:
router#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#ip classifier cIP1 psc 0,1
router(config)#end
router#show ip classifier
ip classifier cip1 psc 0,1
Example 2: The following command deletes the classifier group cIP1:
router#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#no ip classifier cIP1
router#show ip classifier
% no ip-classifier defined
router#
Related Commands: show ip classifier
