QoS Commands
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

configure qosprofile weight
configure qosprofile <qosprofile> {maxbuffer <percent>} {weight <value>}
Description
Modifies the parameters for the default QoS profiles (QP1 and QP8) and defines the parameters for any
user-created QoS profiles (QP2, QP3, QP4, QP5, QP6, and/or QP7).
Syntax Description
Default
●
QoS profiles—QP1 and QP8
●
Maximum buffer—100%
●
Weight—1
Usage Guidelines
You must create a QoS profile before you can configure the user-created QoS profiles. You can modify
the settings on the default QoS profiles (QP1 and QP8) because they are already created.
To assign a QoS profile to a port, use the
configure ports <port_list> {qosprofile}
<qosprofile>
command. If you attempt to configure a QoS profile that you have not created, the
system returns an error message. To configure the type of scheduling you want to use for the entire
switch, use the
configure qosscheduler [strict-priority | weighted-round-robin]
command.
The
maxbuffer
parameter configures the maximum amount of packet buffer, by percentage, that the
packets associated with the specified QoS profile can consume. Regardless of the setting for this
parameter, the system does not drop any packets as long as packet buffer memory remains available
and the current buffer use of the specified QoS profile is below the specified
maxbuffer
setting.
The
weight
parameter configures the relative weighting for each QoS profile. Because each QoS profile
has a default weight of 1, all QoS profiles have equal weighting. If you configure a QoS profile with a
weight of 4, that specified QoS profile is services 4 times as frequently as the remaining QoS profiles,
which still have a weight of 1. If you configure all QoS profiles with a weight of 16, each QoS profile is
serviced equally but for a longer period.
qosprofile
Specifies a QoS profile name. Range is QP1 to QP8; the defaults are QP1 and
QP8.
maxbuffer <percent>
Specifies the percentage of the total buffer you are reserving for this QoS
profile. The range is 1 to 100; the default setting is 100.
weight <value>
Specifies the weight value used for queue service weighting in the weighted-
round-robin scheduler for this QoS profile. The range is 1 to 16; the default is
1.
