QoS > Priority Settings
The Priority Setting page allow users to configure the CoS priority settings on a port or ports. When CoS
tagged packets arrive on the switch, they are mapped to the settings configured here. For example, if a port
has been assigned a MAC priority, the packet that has the CoS priority assigned to a MAC address will be
sent to the CoS queue configured for that MAC address. Once the configuration has been completed, users
may see the results in the Priority Settings Table seen here. After configuring the port priorities, users may
adjust the individual CoS settings on the other windows located in the CoS folder of the Switch.
Figure 4.99 - QoS > Priority Settings
From Port/To Port: Users may select a port or group of ports to assign the priority settings.
Port Priority: Specify the Port Priority is Off or On on the port.
Ethernet Priority: Specify the Ethernet Priority is Off or 802.1p on the port.
IP Priority: Specify the IP Priority is Off or DSCP on the port.

QoS > MAC Priority Settings
When using the MAC Priority mechanism, the packet is classified based on the MAC address field priority in
the MAC priority table entries.
To configure a destination MAC address for a CoS queue, users must adhere to the following steps:
1. Once a destination MAC has been added to the FDB, users must then configure the appropriate
queue to be mapped to this destination MAC address, using the following window.
2. Once the previous parameters are set, users should go to the Priority Settings window located in this
folder and set the egress ports on the switch to MAC Priority. These ports must only be set for MAC
Priority and not for any other priority choice. Please be advised that the default priority setting is for
802.1p and users must change the priority to MAC Priority for this function to work properly. Be sure
that the device with this destination MAC address is connected to the port for which this priority is
configured.

Enter the destination MAC Address and select a Class ID where packets containing this destination MAC
address will be sent. Click Apply to implement changes made.
QoS > IP Priority Settings
When using the IP Priority mechanism, the packet is classified based on the IP address field priority in the IP
priority table entries.
