• A priority group exceeds the maximum number of supported priorities.
• COSQ is mapped to more than one priority group.
• COSQ is mapped to more than one priority group. - Invalid or unsupported transmission selection algorithm
(TSA).
• Bandwidth is congured for an uncongured priority group.
• Total ETS bandwidth mapped in priority groups is not equal to 100%.
• Priorities mapped to a queue use dierent TSAs.

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
