Version Description
9.9(0.0) Introduced on the FN IOM.
9.3(0.0) Introduced on the MXL platform.
Usage Information
You must apply this buffer policy at the interface level for the attributes to be
applicable in conjunction with the DCB input policy.
For each QoS policy buffer, 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. When PFC
detects congestion on a queue for a specified priority, it sends a pause frame for
the 802.1p priority traffic to the transmitting device.
You can use set up both the administrative and peer-related PFC priorities. For
example, you can configure the intended buffer configuration for all 8 priorities. If
you configure the number of lossless queues as 4 and if the administrator-
configured priorities configured within the DCB input policy is applied, then the
configuration for those priorities are pre-designed. However, if the peer-provided
priorities are applied, although a DCB input policy is present, the peer-provided
priorities become effective for buffer configuration. This method of configuration
provides an easy and flexible technique to accommodate both administratively-
configured and peer-configured priorities.
Example
Dell(conf)# qos-policy-buffer test
Dell (conf-qos-policy-buffer)#queue 0 pause no-drop buffer-size
128000 pause-threshold 103360 resume-threshold 83520
Dell(conf-qos-policy-buffer)# queue 4 pause no-drop buffer-size
128000 pause-threshold 103360 resume-threshold 83520
priority-list
Configure the 802.1p priorities for the traffic on which you want to apply an ETS output policy.
Syntax
priority-list value
To remove the priority list, use the no priority-list command.
Parameters
value Enter the priority list value. Separate priority values with a
comma; specify a priority range with a dash; for example,
priority-list 3,5-7. The range is from 0 to 7.
Defaults none
