Apply An Input Policy Map To An Interface; Create Output Policy Maps - Dell Force10 C150 Configuration Manual

On the C-Series and S-Series all traffic is by default mapped to the same queue, Queue 0. If you honor
dot1p on ingress, then you can create service classes based the queueing strategy in
command
globally by entering this command from CONFIGURATION mode.
• All dot1p traffic is mapped to Queue 0 unless
globally.
• Layer 2 or Layer 3 service policies supersede dot1p service classes.

Apply an input policy map to an interface

INTERFACE must be in switchport mode. You can apply the same policy map to multiple interfaces, and
you can modify a policy map after you apply it.
• You cannot apply a class-map and QoS policies to the same interface.
• You cannot apply an input Layer 2 QoS policy on an interface you also configure with
access
• If you apply a service policy that contains an ACL to more than one interface, FTOS uses ACL
optimization to conserves CAM space. The ACL Optimization behavior detects when an ACL already
exists in the CAM and rather than writing it to the CAM multiple times.

Create Output Policy Maps

Create Output Policy Maps
1. Create an output policy map using the command
2. Once you create an output policy map, do one or more of the following:
• Apply an output QoS policy to a queue
• Specify an aggregate QoS policy
• Apply an output policy map to an interface
3. Apply the policy map to an interface. See
