Usage Guidelines
You can use this command to specify or modify the maximum number of packets the queue can hold for a class policy configured in a policy map. The system drops packets that exceed the configured queue-size threshold.
The same queue-limit value applies to both 10G port and 40G port. This queue limit applies to unicast traffic drop class traffic only. For example, if you set the queue-limit for 20480 bytes, then this command will configure the queue-limit for both 10G and 40G ports as 20480 bytes.
You can use this command only for network-qos class maps that do not have “pause” configured.
