6. Assign the DCB policy to the DCB buffer threshold profile on stack ports.
CONFIGURATION mode
S4810-YU-MR-Dell(conf)# dcb-policy buffer-threshold stack-unit all stack-
ports all test
7. Assign the DCB policy to the DCB buffer threshold profile on interfaces. This setting takes
precedence over the default buffer-threshold setting.
INTERFACE mode (conf-if-te)
S4810-YU-MR-Dell(conf-if-te-0/0)#dcb-policy buffer-threshold test
8. Create a QoS policy buffer and enter the QoS Policy Buffer Configuration mode to configure the no-
drop queues, ingress buffer size, buffer limit for pausing, and buffer offset limit for resuming.
CONFIGURATION mode
S4810-YU-MR-Dell(conf)# qos-policy-buffer test
S4810-YU-MR-Dell (conf-qos-policy-buffer)#queue 0 pause no-drop buffer-size
128000 pause-threshold 103360 resume-threshold 83520
S4810-YU-MR-Dell (conf-qos-policy-buffer)# queue 4 pause no-drop buffer-size
128000 pause-threshold 103360 resume-threshold 83520
Applying a DCB Map in a Switch Stack
Apply the same DCB map with PFC and ETS configuration to all stacked ports in a switch stack. You
cannot apply different DCB maps to different stacked switches. This functionality is supported on the
S6000 platform.
To remove all PFC and ETS settings applied to stacked ports from the DCB map and reset PFC and ETS to
their default settings, use the no dcb-map stack-unit all command.
Task Command Command Mode
Apply the specified DCB map on all
ports of the switch stack.
