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, the Dell 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
match ip
After you create a class-map, the Dell 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.
4. Link the class-map to a queue.
POLICY MAP mode
service-queue
Example of Creating a Layer 3 Class Map
Dell(conf)#ip access-list standard acl1
Dell(conf-std-nacl)#permit 20.0.0.0/8
Dell(conf-std-nacl)#exit
Dell(conf)#ip access-list standard acl2
Dell(conf-std-nacl)#permit 20.1.1.0/24 order 0
Dell(conf-std-nacl)#exit
Dell(conf)#class-map match-all cmap1
Dell(conf-class-map)#match ip access-group acl1
