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 IPQoS groupings, clear the IP FDB using the command
clear ipfdb. 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 IP FDB.
❑ 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 document.
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
document. You can also save and reboot the switch.
