The QoS monitor can also be used to verify the QoS configuration and monitor the use
of the QoS policies that are in place. To display QoS information on the switch, use the
following command:
show qosprofile <qosprofile>
Displayed information includes:
• QoS profile name
• Minimum bandwidth
• Maximum bandwidth
• Priority
• A list of all traffic groups to which the QoS profile is applied
Additionally, QoS information can be displayed from the traffic grouping perspective by
using one or more of the following commands:
•
show fdb permanent
— Displays destination MAC entries and their QoS profiles.
•
show switch
— Displays information including PACE enable/disable information.
•
show vlan
— Displays the QoS profile assignments to the VLAN.
•
show ports info {detail}
— Displays information including QoS information
for the port.

If you make a change to the parameters of a QoS profile after a QoS policy has already
been formed (by applying a QoS profile to a traffic grouping), the timing of the
configuration change depends on the traffic grouping involved. To have a change in
QoS profile effect a change in the QoS policy, the following rules apply:
• For destination MAC-based grouping (other than permanent), clear the MAC FDB
using the command
clear fdb
. This command should also be issued after a policy
is first formed, as the policy must be in place before an entry is made in the MAC
FDB. For permanent destination MAC-based grouping, re-apply the QoS profile to
the static FDB entry, as documented. You can also save and reboot the switch.
• For physical and logical groupings of a source port or VLAN, re-apply the QoS
profile to the source port or VLAN, as documented. You can also save and reboot the
switch.
