Workflow to Configure Basic QoS Mode

To configure Basic QoS mode, perform the following:

  1. Select Basic mode for the system by using the QoS Properties page.
  2. Select the trust-behavior using the Global Setting page. The switch supports CoS/802.1p trusted mode and DSCP trusted mode. CoS/802.1p trusted mode uses the 802.1p priority in the VLAN tag. DSCP trusted mode use the DSCP value in the IP header.

If there is any port that, as an exception, should not trust the incoming CoS mark, disable the QoS state on that port using the Interface Settings page.

Enable or disable the global selected trusted mode at the ports by using the Interface Settings page. If a port is disabled without trusted mode, all its ingress packets are forward in best effort. It is recommended that you disable the trusted mode at the ports where the CoS/802.1p and/or DSCP values in the incoming packets are not trustworthy. Otherwise, it might negatively affect the performance of your network
