Configuring QoS
•
QSP 1, 2, 3, 4, and 5 are predefined profiles that are not modifiable and cannot be deleted from the
switch configuration. Note that the OmniSwitch 9900 supports only QSP 1 and 5, but QSP 5 is not
supported on all the other platforms.
•
Creating a new profile is supported only on the OmniSwitch 9900. On all the other OmniSwitch
platforms, only the four predefined profiles (QSP 1, 2, 3, and 4) are available at this time.
•
On the OmniSwitch 9900, creating a new custom profile is allowed by importing one of the predefined
profiles (QSP 1 or 5) into a new profile ID between 6 and 16, then modifying the new profile attributes
as necessary. See
•
There is only one QSP assigned to each QSet instance and only one QSet instance per port or link
aggregate (LAG). However, a LAG may show multiple QSet instances, one for each port that is a
member of the LAG.
•
When a port leaves a LAG, the default QSP 1 profile is associated with the QSet instance for that port.
In other words, if the QSet instance for a port was associated with QSP 4 when the port joined the
LAG, the port is associated with QSP 1 when it leaves the LAG.
The qos qsi qsp command is used to change the QSP for a specific QSet instance (QSI). For example:
-> qos qsi port 1/2 qsp 2
-> qos qsi port 2/1-10 qsp 3
-> qos qsi linkagg 5 qsp 3
To view the QSet profile configuration for the switch, use the
See the "QoS Commands" chapter in the OmniSwitch AOS Release 8 CLI Reference Guide for more
information about the qos qsi qsp and related show commands.
Changing the Default QSet Profile
Consider the following when changing the default QSet profile for the switch:
•
Only the OmniSwitch 6860 and OmniSwitch 6865 support changing the default system profile.
•
The new default profile is applied to all switch ports and link aggregates.
•
A QSP assigned through the qos qsi qsp command overrides the system default QSP assignment. For
example, if the system default QSP is set to 1 and the qos qsi qsp command is used to change the QSP
to 2 on port 1/1/20, the QSP 2 settings are applied to port 1/1/20.
To change the default QSet profile (QSP 1) to one of the other supported profiles (QSP 2, 3, or 4), use the
qos qsp system-default
QSP 2:
-> qos qsp system-default 2
To view the current default QSet profile setting for the switch, use the
command.
Creating a Custom Profile
Creating a custom QSet profile is supported only on the OmniSwitch 9900. The
is used to create a custom profile using one of the 2 predefined QSet profiles as a template. For example,
the following command creates profile 6 (QSP 6) using predefined QSP 5 as the template for the new
profile:
-> qos qsp 6 import qsp 5
