Traffic Class Configuration

The Traffic Class Configuration screen (Figure 3-12) allows you to assign a Low or High traffic classification to any of eight (0 to 7) user_priority values assigned to a received frame on specified switch ports.

Note: If you change the Traffic Class Configuration for any switch in a stack configuration, the entire stack resets with the current configuration settings (see Table 3-1 on page 3-5 for details of the Reset option).

See “ IEEE 802.1p Prioritizing” on page 1-53 for more information about this screen.

Choose Traffic Class Configuration (or press t) from the VLAN Configuration Menu screen to open the Traffic Class Configuration screen.
