Traffic shaping allows you to shape output traffic (egress traffic) on a per-port basis and also per queue on the port. The output traffic is monitored to verify that itconforms to the rate configured on the switch. When excessive traffic is detected on theswitch, the output interface applies the traffic shaping and controls the excess traffic. If theswitch queues overflow, the traffic is dropped.Supported Standards, MIBs and RFCsStandardsIEEE 802.1p Priority QueuingMIBsNo MIBs are supported by this feature.RFCsRFC 2697, A Single Rate Three Color MarkerRFC 2698, A Two Rate Three Color MarkerDefault QoS ConfigurationTable 18-1 shows the default QoS configuration.Table 18-1 Default QoS ConfigurationF e a t u r e D e f a u l tV a l u eThe queue to priority assignment See table 18-2The priority to queue assignment See table 18-3
