Disabling Per-Port Queuing on ATM Interfaces

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:

  1. Specify the ATM interface for which you want to disable per-port queuing.
    host1(config)#interface atm 2/0
  2. Disable per-port queuing on that interface.
    host1(config-if)#no qos-mode-port
