Configuring QoS

Configuring Trusted Ports

By default, all ports (except 802.1Q-tagged ports and mobile ports) are untrusted. The trust setting may be
configured globally on the switch, or on a per-port basis.
To configure the global setting on the switch, use the
-> qos trust ports
To configure individual ports as trusted, use the
number. For example:
-> qos port 3/2 trusted
The global setting is active immediately; however, the port setting requires qos apply to activate the
change. For more information about the qos apply command, see
page 21-46.

Using Trusted Ports With Policies

Whether or not the port is trusted is important if you want to classify traffic with 802.1p bits. If the policy
condition specifies 802.1p, the switch must be able to recognize 802.1p bits. (Note that the trusted port
must also be 802.1Q-tagged as described in
802.1p bits may be set or mapped to a single value using the
example, the qos port command specifies that port 2 on slot 3 will be able to recognize 802.1p bits. A
policy condition (Traffic) is then created to classify traffic containing 802.1p bits set to 4 and destined for
port 2 on slot 3. The policy action (SetBits) specifies that the bits will be reset to 7 when the traffic
egresses the switch. A policy rule called Rule2 puts the condition and the action together.
-> qos port 3/2 trusted
-> policy condition Traffic destination port 3/2 802.1p 4
-> policy action SetBits 802.1p 7
-> policy rule Rule2 condition Traffic action SetBits
To activate the configuration, enter the qos apply command. For more information about the qos apply
command, see "Applying the Configuration" on page
For actions that set 802.1p bits, note that a limited set of policy conditions are supported. For information
about which conditions may be used with an 802.1p action, see
page 21-7.
Note. 802.1p mapping may also be set for Layer 3 traffic, which typically has the 802.1p bits set to zero.

Verifying the QoS Port and Queue Configuration

To display information about QoS ports and queues, use the following commands:
show qos port
show qos queue
See the OmniSwitch CLI Reference Guide for more information about the syntax and displays for these
commands.
