Licensing Requirements for Class-based Quality-of-Service MIB
This feature does not require a license. Any feature not included in a license package is bundled with the Cisco
NX-OS system images and is provided at no extra charge to you. For a complete explanation of the Cisco
NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide.
Prerequisite for Class-based Quality-of-Service MIB
•
You must enable QoS Statistics under show policy-map interface to view statistics under Class-based
Quality-of-Service MIB. For more information, refer Enabling QoS Statistics under show policy-map
interface.
Guidelines and Limitations for Class-based Quality-of-Service MIB
The guidelines and limitations for viewing statistics are as follows:
•
Statistics can be viewed per Access Control Entry (ACE) in an Access Control List (ACL) if there is no
policer attached.
•
Statistics can be viewed per ACE in an ACL, if there is only one ACE in the ACL and if a policer is
attached.
•
Statistics cannot be viewed per ACE in an ACL, if there are more than one ACEs in an ACL and a
policer is attached.
•
The limitations above apply to QoS-based matches as well, such as match dscp dscp-list , match
precedence precedence-list and so on.
•
Statistics cannot be viewed with match-all rules.
•
Statistics can be viewed only with match-any.
•
For instances when the statistics do not get enabled without a policer, follow these steps:
•
Create a class. You can add as many rules as required.
•
Create a policy-map and attach the above class to it.
•
Add a dummy policer to it (if you do not require a real policer).
