I want to understand some thing about WFQ. Find below the statement about the WFQ.
" WFQ allows you to give low volume traffic, such as telnet session priority over high volume traffic, such as FTP session"
As per my understanding WFQ uses single queue per flow. But How does it know to what session it need to provide the priority. Does it has the intelligent to detemine based on the protocol ( may using NBAR) or Uses the DSCP value or etc ?
If it DSCP then is it must to classify the traffic and mark the DSCP value for the above statement to be true.
