QoS Profiles
101
A QoS profile does not alter the behavior of the switch until it is assigned
to a traffic grouping. The settings of the default profiles are shown in
Table 25
.
Modifying a QoS
Profile
You can modify the profile defaults as desired. To modify the parameters
of an existing QoS profile, use the following command:
config qosprofile <qosname> {minbw <percent>}
{maxbw <percent>} {priority <level>}
The QoS profiles
qp1
through
qp8
are mapped directly to the eight
hardware queues on every switch port. Any changes to parameters of the
eight pre-defined QoS profiles have the corresponding effect on the
ports. The direct mapping is straight-forward to understand and
configure.
Queue setting at any instant at a port depends on the QoS profiles
associated with the traffic through that port. The minimum bandwidth is
the sum of all the minimum values of the QoS profiles sharing a queue.
The maximum bandwidth setting is equal to the highest bandwidth
setting of all the profiles that are sharing that queue.
