Classify Trac
Class maps dierentiate trac so that you can apply separate quality of service policies to dierent types of trac.
For both class maps, Layer 2 and Layer 3, Dell EMC Networking OS matches packets against match criteria in the order that you congure
them.
Creating a Layer 3 Class Map
A Layer 3 class map dierentiates ingress packets based on the DSCP value or IP precedence, and characteristics dened in an IP ACL. You
can also use VLAN IDs and VRF IDs to classify the trac using layer 3 class-maps.
You may specify more than one DSCP and IP precedence value, but only one value must match to trigger a positive match for the class
map.
NOTE: IPv6 and IP-any class maps cannot match on ACLs or VLANs.
Use step 1 or step 2 to start creating a Layer 3 class map.
1 Create a match-any class map.
CONFIGURATION mode
class-map match-any
2 Create a match-all class map.
CONFIGURATION mode
class-map match-all
3 Specify your match criteria.
CLASS MAP mode
[seq sequence number] match {ip | ipv6 | ip-any}
After you create a class-map, Dell EMC Networking OS places you in CLASS MAP mode.
Match-any class maps allow up to ve ACLs. Match-all class-maps allow only one ACL.
NOTE
: Within a class-map, the match rules are installed in the sequence number order.
4 Link the class-map to a queue.
POLICY MAP mode
service-queue
Example of Creating a Layer 3 Class Map
Examples of Creating a Layer 3 IPv6 Class Map
The following example matches the IPv6 trac with a DSCP value of 40:
DellEMC(conf)# class-map match-all test
DellEMC(conf-class-map)# match ipv6 dscp 40
The following example matches the IPv4 and IPv6 trac with a precedence value of 3:
DellEMC(conf)# class-map match-any test1
DellEMC(conf-class-map)#match ip-any precedence 3
