DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
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)#
87-11 mls qos scheduler
This command is used to configure the scheduling mechanism. Use the no command to reset the packet
scheduling mechanism to the default.
mls qos scheduler {sp | rr | wrr | wdrr | ets}
no mls qos scheduler
Parameters
sp
rr
wrr
wdrr
Default
The default queue scheduling algorithm is WRR.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
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 queue in a round robin order. Initially, each queue sets its credit counter to a
configurable quantum value. Every time a packet from a CoS queue is sent, the size of the packet is
Specifies that all queues are in strict priority scheduling.
Specifies that all queues are in round-robin scheduling.
Specifies the queues in the frame count weighted round-robin
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 scheduling. If the weight of a queue be
configured to zero, the queue is in the SP scheduling mode.
