C H A P T E R 8 Quality of Service (QoS)
Modifying a QoS Policy
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.
Configuring QoS
Table 40 describes the commands used to configure QoS.
