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 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(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
Dell(conf-if-te-1/1)#service-policy input pmap
Examples of Creating a Layer 3 IPv6 Class Map
The following example matches IPv6 trac with a DSCP value of 40.
Dell(conf)# class-map match-all test
Dell(conf-class-map)# match ipv6 dscp 40
The following example matches IPv4 and IPv6 trac with a precedence value of 3.
Dell(conf)# class-map match-any test1
Dell(conf-class-map)#match ip-any precedence 3
Creating a Layer 2 Class Map
All class maps are Layer 3 by default; however, you can create a Layer 2 class map by specifying the layer2 option with the class-map
command.
A Layer 2 class map dierentiates trac according to 802.1p value and/or VLAN and/or characteristics dened in a MAC ACL..
