threshold is reached (as shown in the following illustration); this procedure is the early detection part of WRED. If the maximum threshold,
for example, 2000KB, is reached, all incoming packets are dropped until the buer space consumes less than 2000KB of the specied
trac.

You can create a custom WRED prole or use one of the ve pre-dened proles.
