QoS Workflow
To configure general QoS parameters, perform the following:
STEP 1 Enable QoS by using the QoS Properties Page to select the trust mode.
STEP 2 Assign each interface a default CoS or DSCP priority by using the QoS Properties
Page
.
STEP 3 Assign the schedule method (Strict Priority or WRR) and bandwidth allocation for
WRR to the egress queues by using the
Queue Page .
STEP 4 Designate an egress queue to each IP DSCP/TC value with the DSCP to Queue
Page. If the switch is in DSCP trusted mode, incoming packets are put into the
egress queues based on the their DSCP/TC value.
STEP 5 Designate an egress queue to each CoS/802.1p priority. If the switch is in CoS/
802.1 trusted mode, all incoming packets will be put into the designated egress
queues according to the CoS/802.1p priority in the packets. This is done by using
the CoS/802.1p to Queue Page.
STEP 6 Enter bandwidth and rate limits in the following pages:
a. Set egress shaping per queue by using the Egress Shaping Per Queue Page.
b. Set ingress rate limit and egress shaping rate per port by using the Bandwidth
Page.

Displaying QoS Properties
The QoS Properties Page contains fields for enabling QoS and selecting the trust
mode to be used. In addition, the default CoS priority or DSCP value for each
interface can be defined.
To e n a b l e Q o S :
STEP 1 Click Quality of Service > General > QoS Properties. The QoS Properties Page
opens.
STEP 2 Enable QoS on the switch.
STEP 3 Select a trust mode (CoS/802.1p or DSCP) and click Apply.
