OLICY FOR A
VLAN
Once you have defined a QoS profile, you can apply that profile to a VLAN to define
the QoS Policy for that VLAN. You must have Administrator or Manager access to
perform this function.
All VLANs are created using the default QP1 profile. To apply a different QoS Profile as
QoS policy for a VLAN:
1 Click the Policy button at the top left of the Quality of Service Manager window.
The Modify QoS Policy dialog box appears, as shown in Figure 7-6.
Figure 7-6:
The Modify QoS Policy dialog box
2 Select the VLAN from the drop-down list in the VLAN field.
The Profile field displays the current QoS profile. If the field displays <multiple>,
the VLAN includes ports on multiple Summit switches that use different QoS
profiles.
3 Select a profile from the pull down list in the Profile field.
4 Click Apply to change the QoS Policy for the VLAN.
When you apply a new QoS profile to a VLAN, it changes the QoS configuration for all
Summit switches that participate in the VLAN. If the VLANs policy was previously
<multiple>, the Apply QoS Policy action sets all the different QoS profiles to the one
specified here.
Profiles can be created or deleted from the switch only when the switch is in
egress mode. If the switch is in ingress mode, the operation will fail.
