The following example matches IPv6 traffic 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 traffic 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 differentiates traffic according to 802.1p value and/or VLAN and/or characteristics
defined in a MAC ACL..
Use Step 1 or Step 2 to start creating a Layer 2 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 mac
After you create a class-map, Dell Networking OS places you in CLASS MAP mode.
Match-any class maps allow up to five access-lists. Match-all class-maps allow only one. You can match
against only one VLAN ID.
4 Link the class-map to a queue.
POLICY MAP mode
service-queue
Determining the Order in Which ACLs are Used to Classify
Traffic
When you link class-maps to queues using the
service-queue
command, Dell Networking OS matches the
class-maps according to queue priority (queue numbers closer to 0 have lower priorities).
For example, as described in the previous example, class-map
cmap2
is matched against ingress packets
before
cmap1
.
ACLs
acl1
and
acl2
have overlapping rules because the address range 20.1.1.0/24 is within 20.0.0.0/8.
Therefore (without the keyword
order
), packets within the range 20.1.1.0/24 match positive against
cmap1
