Configuring Queuing and Scheduling
8. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1 configure terminal
Example:
switch# configure terminal
switch(config)#
Step 2
policy-map type queuing {[match-first]
policy-map-name}
Example:
switch(config)# policy-map type queuing
shape_queues
switch(config-pmap-que)#
Step 3 class type queuingclass-name
Example:
switch(config-pmap-que)# class type queuing
c-out-q1
switch(config-pmap-c-que)#
Step 4 Assign a minimum rate of the interface bandwidth or assign
the percentage of the bandwidth that remains:
• Bandwidth percent:
bandwidth {percent percent}
• Bandwidth remaining percent:
bandwidth remaining percent percent
Example:
• Bandwidth percent:
switch(config-pmap-c-que)# bandwidth percent
25
• Bandwidth remaining percent:
switch(config-pmap-c-que)# bandwidth remaining
percent 25
Step 5 (Optional) Repeat Steps 3 and 4 to assign tail drop
thresholds for other queue classes.
Step 6
exit
Example:
switch(config-cmap-que)# exit
switch(config)#
Purpose
Enters global configuration mode.
Configures the policy map of type queuing and then enters
policy-map mode for the policy-map name you specify.
Policy-map names can contain alphabetic, hyphen, or
underscore characters, are case sensitive, and can be up to
40 characters.
Configures the class map of type queuing and then enters
policy-map class queuing mode. Class queuing names are
listed in the previous System-Defined Type queuing Class
Maps table.
Exits policy-map queue mode and enters global
configuration mode.

Configuring Bandwidth and Bandwidth Remaining
• Bandwidth percent:
Assigns a minimum rate of the interface bandwidth to
an output queue as the percentage of the underlying
interface link rate. The range is from 0 to 100.
The example shows how to set the bandwidth to a
minimum of 25 percent of the underlying link rate.
• Bandwidth remaining percent:
Assigns the percentage of the bandwidth that remains
to this queue. The range is from 0 to 100.
The example shows how to set the bandwidth for this
queue to 25 percent of the remaining bandwidth.
