Hello, Can anyone answer the 2 questions below? 1. What's the difference between the NS command "queue-limit" and the configuration parameter "limit_" of Queue objects? 2. Is the unit of "maxqueue_" of SFQ in bytes or pkts? Looking forward, Jiangbin Yang ---------------------------------------- Univ. of Toronto, Industrial Engineering http://www.ecf.toronto.edu/~jiangb ----------------------------------------
