ProSAFE FS526Tv2, FS726Tv2, and FS728TLP Smart Switches 2. Select whether to configure physical ports, link aggregation groups (LAGs), or both by clicking one of the following links above the table heading: • PORTS. Only physical ports display. This is the default setting. • LAGS. Only LAGs display. • All. Both physical ports and LAGs display. 3. Select whether to configure a single port, a group of ports, or all ports (for the sake of simplicity in this procedure, LAGs are also considered ports): • To configure a single port, select the check box next to the port that you want to configure. The information for the selected port displays in the menu in the table heading. • To configure a group of ports, select the check boxes for the individual ports that you want to configure. • To configure all ports, select the check box at the left in the table heading. 4. From the Interface Trust Mode menu, select the trust mode: • Untrusted. The priority designation of an incoming packet is considered untrusted and the smart switch uses the port default priority values instead. You can configure the port default priority values on the Interface Queue Configuration screen (see Configure CoS Queues and Queue Options for Physical Ports and LAGs on page 143). • 802.1p. The trust mode for all ports and LAGs is 802.1p. You can configure the priority-to-queue mapping on the 802.1p to Queue Mapping screen (see Configure 802.1p to Queue Mapping on page 146). • DSCP. The trust mode for all ports and LAGs is DSCP. You can configure the DSCP-to-queue mapping on the DSCP to Queue Mapping screen (see Configure DSCP to Queue Mapping on page 147). 5. In the Interface Shaping Rate field, specify the maximum allowed bandwidth. Enter a value in the range from 16 to 16384. The default value is 0. 6. Click the Apply button. The settings are saved. The per-interface setting overrides the global setting. Configure CoS Queues and Queue Options for Physical Ports and LAGs You can associate each port and LAG with one of the eight egress queues (from 0 through 7). In addition, for each port and LAG, you configure the bandwidth that the egress queue uses and the scheduling of packet transmission. The queue management type is fixed at the taildrop type: If the port or LAG is oversubscribed, packets that arrive at the port or LAG are dropped. Configure Class of Service 143

You can associate each port and LAG with one of the eight egress queues (from 0
through
7). In addition, for each port and LAG, you configure the bandwidth that the egress
queue uses and the scheduling of packet transmission. The queue management type is fixed
at the taildrop type: If the port or LAG is oversubscribed, packets that arrive at the port or
LAG are dropped.
