DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Command Mode Global Configuration Mode. Usage Guideline When a packet is received by an interface, based on a DSCP mutation map, the incoming DSCP can be mutated to another DSCP immediately before any QoS operations. The DSCP mutation is helpful to integrate domains with different DSCP assignments. When configuring a named DSCP mutation map, note the following:  Enter multiple commands to map additional DSCP values to a mutated DSCP value.  Enter a separate command for each mutated DSCP value. The DSCP-CoS map and DSCP-color map will still be based on the packet's original DSCP. All the subsequent operations will base on the mutated DSCP. Example This example shows how to map DSCP 30 to the mutated DSCP value 8, DSCP 20 to the mutated DSCP 10, with the mutation map named "mutemap1". Switch# configure terminal Switch(config)# mls qos map dscp-mutation mutemap1 30 to 8 Switch(config)# mls qos map dscp-mutation mutemap1 20 to 10 Switch(config)# 51-8 mls qos scheduler This command is used to configure the scheduling mechanism. Use the no form of this command to revert to the default setting. mls qos scheduler {sp | rr | wrr | wdrr} no mls qos scheduler Parameters sp rr wrr wdrr Specifies that all queues are in Strict Priority (SP) scheduling. Specifies that all queues are in Round-Robin (RR) scheduling. Specifies the queues in the frame count Weighted Round-Robin (WRR) scheduling. If the weight of a queue be configured to zero, the queue is in the SP scheduling mode. Specifies the queues of all ports in the frame length (quantum) Weighted Deficit Round-Robin (WDRR) scheduling. If the weight of a queue be configured to zero, the queue is in the SP scheduling mode. Default The default queue scheduling algorithm is WRR. Command Mode Interface Configuration Mode. Usage Guideline Specify schedule algorithms to WRR, SP, RR or WDRR for the output queue. By default, the output queue scheduling algorithm is WRR. WDRR operates by serving an accumulated set of backlogged credits in the transmit 380

DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide
380
Command Mode
Global Configuration Mode.
Usage Guideline
When a packet is received by an interface, based on a DSCP mutation map, the incoming DSCP can be mutated
to another DSCP immediately before any QoS operations. The DSCP mutation is helpful to integrate domains with
different DSCP assignments.
When configuring a named DSCP mutation map, note the following:
Enter multiple commands to map additional DSCP values to a mutated DSCP value.
Enter a separate command for each mutated DSCP value.
The DSCP-CoS map and DSCP-co
lor map will still be based on the packet’s original DSCP. All the subsequent
operations will base on the mutated DSCP.
Example
This example shows how to map DSCP 30 to the mutated DSCP value 8, DSCP 20 to the mutated DSCP 10, with
the mutation map named
“mutemap1”.
Switch# configure terminal
Switch(config)# mls qos map dscp-mutation mutemap1 30 to 8
Switch(config)# mls qos map dscp-mutation mutemap1 20 to 10
Switch(config)#

mls qos scheduler
This command is used to configure the scheduling mechanism. Use the
no
form of this command to revert to the
default setting.
mls qos scheduler {sp | rr | wrr | wdrr}
no mls qos scheduler
Parameters
sp
Specifies that all queues are in Strict Priority (SP) scheduling.
rr
Specifies that all queues are in Round-Robin (RR) scheduling.
wrr
Specifies the queues in the frame count Weighted Round-Robin (WRR)
scheduling. If the weight of a queue be configured to zero, the queue is in the SP
scheduling mode.
wdrr
Specifies the queues of all ports in the frame length (quantum) Weighted Deficit
Round-Robin (WDRR) scheduling. If the weight of a queue be configured to zero,
the queue is in the SP scheduling mode.
Default
The default queue scheduling algorithm is WRR.
Command Mode
Interface Configuration Mode.
Usage Guideline
Specify schedule algorithms to WRR, SP, RR or WDRR for the output queue. By default, the output queue
scheduling algorithm is WRR. WDRR operates by serving an accumulated set of backlogged credits in the transmit
