www.dell.com | support.dell.com Port-based QoS Configurations You can configure the following QoS features on an interface: • Set dot1p Priorities for Incoming Traffic on page 852 • Configure Port-based Rate Policing on page 854 • Configure Port-based Rate Limiting on page 855 • Configure Port-based Rate Shaping on page 856 • Broadcast Storm Control on page 1043 Set dot1p Priorities for Incoming Traffic Change the priority of incoming traffic on the interface using the command dot1p-priority from INTERFACE mode, as shown in Figure 41-2. FTOS places traffic marked with a priority in a queue based on Table 41-2. If you set a dot1p priority for a port-channel, all port-channel members are configured with the same value. You cannot assign a dot1p value to an individual interfaces in a port-channel. FTOS Behavior: The C-Series and S-Series distribute eight dot1p priorities across four data queues. This is different from the E-Series, which distributes eight dot1p priorities across eight queues (Table 41-2).
