Configuration Notes for QoS Options

ICX devices do not support marking and prioritization simultaneously with the same rule and do not support DSCP CoS mapping at all. Instead, you must create two separate rules. In other words, you can mark a rule with DSCP or 802.1p information, or you can prioritize a rule based on DSCP or 802.1p information. You can enable only one of the following ACL options per rule:

  • 802.1p-priority-marking
  • dscp-marking
  • internal-priority-marking

Note: The internal-priority-marking option is not supported for egress ACLs.

For example, any one of the following commands is supported:

device(config)# ip access-list extended acl101 
device(config-ext-ipacl-acl101)# permit ip any any dscp-marking 43

or 

device(config)# ip access-list extended acl101 
device(config-ext-ipacl-acl101)# permit ip any any internal-priority-marking 6

or 

device(config)# ip access-list extended acl101  
device(config-ext-ipacl-acl101)# permit ip any any dscp-marking 43 802.1p-priority-marking 4 internal-priority-marking 6
