Reference Guide
DCB output-policy error: If an error occurs in an DCB 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 DCB output policy. If no DCB output policy was previously applied, the port is reset to the
default ETS parameters.
Creating an ETS Priority Group
An ETS priority group specifies the range of 802.1p priority traffic to which a QoS output policy with ETS
settings is applied on an egress interface. You can associate a priority group to more than one ETS output
policy on different interfaces.
1. Create an ETS priority group to use with an ETS output policy.
CONFIGURATION mode
priority-group group-name
The maximum is 32 characters.
2. Configure the priority-group identifier.
PRIORITY-GROUP mode
set-pgid value
The range is from 0 to 7.
The default is none.
3. Configure the 802.1p priorities for the traffic on which you want to apply an ETS output policy.
PRIORITY-GROUP mode
priority-list value
The range is from 0 to 7.
The default is none.
Separate priority values with a comma. Specify a priority range with a dash. For example, priority-list
3,5-7.
4. Exit priority-group configuration mode.
PRIORITY-GROUP mode
exit
5. Repeat Steps 1 to 4 to configure all remaining dot1p priorities in an ETS priority group.
Dell Networking OS Behavior: A priority group consists of 802.1p priority values that are grouped for
similar bandwidth allocation and scheduling, and that share latency and loss requirements. All 802.1p
priorities mapped to the same queue must be in the same priority group.
Configure all 802.1p priorities in priority groups associated with an ETS output policy (refer to Applying an
ETS Output Policy for a Priority Group to an Interface). You can assign each dot1p priority to only one
priority group.
