Classify Trac
Class maps dierentiate trac so that you can apply separate quality of service policies to dierent types of trac.
For both class maps, Layer 2 and Layer 3, the Dell Networking OS matches packets against match criteria in the order that you
congure them.
Creating a Layer 3 Class Map
A Layer 3 class map dierentiates ingress packets based on the DSCP value or IP precedence, and characteristics dened in an IP
ACL. You can also use VLAN IDs and VRF IDs to classify the trac 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
