qos-policy-output ets
To configure the ETS bandwidth allocation and scheduling for priority traffic, create a QoS output policy.
Syntax
qos-policy-output policy-name ets
To remove the QoS output policy, use the no qos-policy-output ets command.
Parameters
policy-name Enter the policy name. The maximum is 32 characters.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
If an error occurs in an ETS output-policy configuration, the configuration is ignored and the scheduler
and bandwidth allocation settings are reset to the ETS default values (all priorities are in the same ETS
priority group and bandwidth is allocated equally to each priority).
If an error occurs when a port receives a peer’s ETS configuration, the port’s configuration is reset to the
previously configured ETS output policy. If no ETS output policy was previously applied, the port is reset
to the default ETS parameters.

Commands
● scheduler — schedules the priority traffic in port queues.
● bandwidth-percentage — bandwidth percentage allocated to the priority traffic in port queues.
qos-policy-buffer
Create a QoS policy buffer and enter the configuration mode to configure the no-drop queues, ingress buffer size, buffer limit
for pausing, and buffer offset limit for resuming.
Syntax
qos-policy-buffer queue queue-num pause no-drop queue buffer-size
size pause-threshold threshold-value resume-offset threshold-value shared-
threshold-weight size
Parameters
policy-name Name of the QoS policy buffer that is applied to an interface for this setting
to be effective in conjunction with the DCB input policy. You can specify the
shared buffer threshold limit, the ingress buffer size, buffer limit for pausing the
acceptance of packets, and the buffer offset limit for resuming the acceptance
of received packets. This method of configuration enables different peer-provided
and administrative priorities to be set up because the intended queue is directly
configured instead of determining the priority to queue mapping for local and
remote parameters.
queue 0 to queue
7
Specify the queue number to which the QoS policy buffer parameters apply
pause Pause frames to be sent at the specified buffer limit levels and pause packet
settings
no-drop The packets for this queue must not be dropped
value Enter a number in the range of 0 to 7 to denote the priority to be allocated to the
dynamic buffer control mechanism
buffer-size Ingress buffer size
