• Incompatible TC TSA.
Conguring the Dynamic Buer Method
To congure the dynamic buer capability, perform the following steps:
1 Enable the DCB application. By default, DCB is enabled and link-level ow control is disabled on all interfaces.
CONFIGURATION mode
S6000-109-Dell(conf)#dcb enable
2 Congure the shared PFC buer size and the total buer size. A maximum of 4 lossless queues are supported.
CONFIGURATION mode
S6000-109-Dell(conf)#dcb pfc-shared-buffer-size 4000
S6000-109-Dell(conf)#dcb pfc-total-buffer-size 5000
3 Congure the number of PFC queues.
CONFIGURATION mode
Dell(conf)#dcb enable pfc-queues 4
The number of ports supported based on lossless queues congured will depend on the buer.
For each priority, you can specify the shared buer threshold limit, the ingress buer size, buer limit for pausing the acceptance of
packets, and the buer oset limit for resuming the acceptance of received packets.
4 Congure the prole name for the DCB buer threshold
CONFIGURATION mode
Dell(conf)#dcb-buffer-threshold test
5
DCB-BUFFER-THRESHOLD mode
Dell(conf-dcb-buffer-thr)# priority 0 buffer-size 52 pause-threshold 16 resume-offset 10
shared-threshold-weight 7
6 Assign the DCB policy to the DCB buer threshold prole on stack ports.
CONFIGURATION mode
Dell(conf)# dcb-policy buffer-threshold stack-unit all stack-ports all test
7 Assign the DCB policy to the DCB buer threshold prole on interfaces. This setting takes precedence over the default buer-
threshold setting.
INTERFACE mode (conf-if-te)
Dell(conf-if-te-0/0)#dcb-policy buffer-threshold test
8 Create a QoS policy buer and enter the QoS Policy Buer Conguration mode to congure the no-drop queues, ingress buer size,
buer limit for pausing, and buer oset limit for resuming.
CONFIGURATION mode
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
