www.dell.com | support.dell.com WRED can be used in combination with storm control to regulate broadcast and unknown-unicast traffic. This feature is available through an additional option in command storm-control [broadcast | unknown-unicast] at CONFIGURATION. See the FTOS Command Line Reference for information on using this command. Using the command storm-control broadcast 50 out wred-profile, for example, first the total bandwidth that broadcast traffic can consume is reduced to 50% of line rate. Even though broadcast traffic is restricted, the rate of outgoing broadcast traffic might be greater than other traffic, and if so, broadcast packets would consume too much buffer space. So, the wred-profile option is added to limit the amount of buffer space that broadcast traffic can consume. Display Default and Configured WRED Profiles Display default and configured WRED profiles and their threshold values using the command show qos wred-profile from EXEC mode, as shown in Figure 31-14.
