QoS Commands
configure qosprofile
configure qosprofile <qosprofile> minbw <min_percent> maxbw <max_percent>
priority <level> {[minbuf <percent> maxbuf <number> [K | M] | maxbuff
<number> [K | M] | <portlist>]}
Description
Modifies the default QoS profile parameters.
Syntax Description
Default
• Minimum bandwidth—0%
• Maximum bandwidth—100%
• Priority—low
• Minimum buffer percent—0%
• Maximum buffer size—256K
Usage Guidelines
On Summit chipset-based switches in ingress mode, any changes to parameters of the four predefined
QoS profiles have the corresponding effect on the ports to which they are mapped.
The
minbuf
parameter reserves buffer memory for use exclusively by a QoS profile across all affected
ports. The default value for buffer settings is 0%. The sum of all QoS profile buffer parameters should
not exceed 100%. The
maxbuf
parameter allows you to set a maximum buffer for each queue, so that a
single queue will not consume all of the unallocated buffer space. You should not modify the buffer
parameter unless specific situations and application behavior indicate. You must reboot the switch for
changes to this parameter to take effect.
qosprofile Specifies a QoS profile name.
min_percent Specifies a minimum bandwidth percentage for this queue. The default setting
is 0.
max_percent Specifies the maximum bandwidth percentage this queue is permitted to use.
The default setting is 100.
level Specifies a service priority setting. Settings include low, lowHi, normal,
normalHi, medium, mediumHi, high, and highHi. The default setting is low.
Available in egress mode only.
percent Specifies the minimum percentage of the buffer set aside for the queue.
Cumulative % of the queues should not exceed 100%.
number Specifies the maximum buffer size in either M or K bytes. The range is 0 to
16384. The default is 256 K. You must reboot for changes to take effect.
• K indicates the value is in K bytes.
• M indicates the value is in M bytes.
portlist Specifies a list of ports or slots and ports to which the parameters apply. May
be in the form 1, 2, 3-5, 2:5, 2:6-2:8.
