The order can range from 0 to 254.
By default, all ACL rules have an order of 255.
Displaying Configured Class Maps and Match Criteria
To display all class-maps or a specific class map, use the following command.
Dell Networking OS Behavior: An explicit "deny any" rule in a Layer 3 ACL used in a (match any or match
all) class-map creates a "default to Queue 0" entry in the CAM, which causes unintended traffic
classification. In the following example, traffic is classified in two Queues, 1 and 2. Class-map ClassAF1 is
"match any," and ClassAF2 is "match all".
• Display all class-maps or a specific class map.

match ip dscp 18
Dell#show running-config ACL

seq 10 deny ip any any
!
ip access-list extended AF1-FB2
seq 5 permit ip host 23.64.0.3 any
seq 10 deny ip any any
!
ip access-list extended AF2
seq 5 permit ip host 23.64.0.5 any
seq 10 deny ip any any
In the previous example, the ClassAF1 does not classify traffic as intended. Traffic matching the first
match criteria is classified to Queue 1, but all other traffic is classified to Queue 0 .
When you remove the explicit "deny any" rule from all three ACLs, the CAM reflects exactly the desired
classification.
