Creating a Layer 3 Class Map
A Layer 3 class map differentiates ingress packets based on the DSCP value or IP precedence, and
characteristics defined in an IP ACL. You can also use VLAN IDs and VRF IDs to classify the traffic 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 | ipv6 | ip-any}
After you create a class-map, Dell Networking OS places you in CLASS MAP mode.
Match-any class maps allow up to five 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(config-std-nacl)#permit 20.0.0.0/8
Dell(config-std-nacl)#exit
Dell(conf)#ip access-list standard acl2
Dell(config-std-nacl)#permit 20.1.1.0/24 order 0
Dell(config-std-nacl)#exit
Dell(conf)#class-map match-all cmap1
Dell(conf-class-map)#match ip access-group acl1
Dell(conf-class-map)#exit
Dell(conf)#class-map match-all cmap2
Dell(conf-class-map)#match ip access-group acl2
Dell(conf-class-map)#exit
Dell(conf)#policy-map-input pmap
Dell(conf-policy-map-in)#service-queue 3 class-map cmap1
Dell(conf-policy-map-in)#service-queue 1 class-map cmap2
Dell(conf-policy-map-in)#exit
Dell(conf)#interface tengigabitethernet 1/1/1
Dell(conf-if-te-1/1/1)#service-policy input pmap
