Configuring Standard QoS Chapter 28 Configuring QoS Default Egress Queue Configuration Table 28-9 shows the default egress queue configuration for each queue-set when QoS is enabled. All ports are mapped to queue-set 1. The port bandwidth limit is set to 100 percent and rate unlimited. Table 28-9 Default Egress Queue Configuration Feature Queue 1 Queue 2 Queue 3 Buffer Allocation 25 percent 25 percent 25 percent WTD Drop Threshold 1 100 percent 50 percent 100 percent WTD Drop Threshold 2 100 percent 50 percent 100 percent Reserved Threshold 50 percent 100 percent 50 percent Maximum Threshold 400 percent 400 percent 400 percent SRR Shaped Weights 25 0 0 (absolute) 1 SRR Shared Weights 2 25 25 25 1. A shaped weight of zero means that this queue is operating in shared mode. 2. One quarter of the bandwidth is allocated to each queue. Queue 4 25 percent 100 percent 100 percent 50 percent 400 percent 0 25 Table 28-10 shows the default CoS output queue threshold map when QoS is enabled. Table 28-10 Default CoS Output Queue Threshold Map CoS Value Queue ID - Threshold ID 0, 1 2, 3 4 2-1 3-1 4-1 5 6, 7 1 -1 4 - 1 Table 28-11 shows the default DSCP output queue threshold map when QoS is enabled. Table 28-11 Default DSCP Output Queue Threshold Map DSCP Value Queue ID - Threshold ID 0-15 16-31 32-39 40-47 48-63 2-1 3-1 4-1 1-1 4-1 Default Mapping Table Configuration The default CoS-to-DSCP map is shown in Table 28-12 on page 28-47. The default IP-precedence-to-DSCP map is shown in Table 28-13 on page 28-48. The default DSCP-to-CoS map is shown in Table 28-14 on page 28-50. The default DSCP-to-DSCP-mutation map is a null map, which maps an incoming DSCP value to the same DSCP value. The default policed-DSCP map is a null map, which maps an incoming DSCP value to the same DSCP value (no markdown). 28-28 Catalyst 3560 Switch Software Configuration Guide 78-16156-01
