(or the queues are empty), TCGs that have not met their maximum bandwidth limit are scheduled. Once the limits for a TCG are satisfied (maximum bandwidth, no frames available for transmission, etc.), the scheduler moves to the next TCG. If no minimum or maximum bandwidth limits are configured, TCGs are serviced by the second-level scheduler using the configured TCG weights to define the relative bandwidth allocation among the TCGs. When an egress port is congested, packets are selected for discard using the configured taildrop or WRED discipline. Minimum TCG bandwidth, maximum TCG bandwidth, and TCG weights are metered to within approximately 3% of the link bandwidth. In the case that all TCGs are configured as strict priority, inter-TCG scheduling reverts to Weighted Deficit Round Robin scheduling based on the configured TCG weights. 834 Configuring Data Center Bridging Features
