You can remove per-port queuing on ATM interfaces and restore the default integrated mode setting.
When per-port queuing is disabled, both the VC and port backpressure are enabled. The SAR scheduler performs significant buffering, and the HRR scheduler does minimal scheduling. The atm-vc node command must appear in the QoS profile attached to the ATM port.
To disable per-port queuing:
- host1(config)#interface atm 2/0
- host1(config-if)#no qos-mode-port
