Exactly my thoughts. Now, what about the directional questions?

In fact, it is quite a useful command much of the time. If the task said to configure such and such percent of the bandwidth I would first set the bandwidth to the line speed using the bandwidth command. Then, I would set Max-reserved-bandwidth to 100 to make the math easier. If you do "bandwidth-percent 20" with the default "max-reserved-bandwidth 75" what you are getting is actually 20% of 75% ...to me that is more difficult. If you set max-reserved bandwidth to 100, you actually get 20% of the entire interface bandwidth.

I was working on Lab 3 in V2 of the BLS and I know they show doing task 8.1 with a queue-list but I wanted to try it differently. I did it in MQC: class-map match-all TELNET match protocol telnet class-map match-all HTTP match protocol http class-map match-all FTP match protocol ftp class-map match-all iIPV6 match protocol ipv6 ! ! policy-map Bandwidth class HTTP bandwidth percent 20 class FTP bandwidth percent 20 class IPV6 bandwidth percent 25 class TELNET bandwidth percent 15 Now, this works if you stick to the idea of 'available bandwidth' vs 'linespeed'. If it said set so-and-so to '20% of line speed' I would use a queue-list I guess and not mess with max-reserver-bandwidth. But it says 'bandwidth' so if I use mqc with this config on a 128k circuit I don't end up with enough available bandwidth to do it unless I mess with m-r-b. What's the difference if I do? Queue-list don't care so they don't reserver m-r-b for class default but MQC does. Also there is a lingering question I have: is a queue-list bidirectional? A service-policy would need to be applied inbound and outbound no? (It's too late in the game for me to be asking these dumb questions) So finally, this is what I ended up with: class-map match-all TELNET match protocol telnet class-map match-all HTTP match protocol http class-map match-all FTP match protocol ftp class-map match-all iIPV6 match protocol ipv6 ! ! policy-map Bandwidth class HTTP bandwidth percent 20 class FTP bandwidth percent 20 class IPV6 bandwidth percent 25 class TELNET bandwidth percent 15 interface Multilink1 ip address 110.99.96.5 255.255.255.252 ip bandwidth-percent eigrp 100 15 ip pim sparse-mode ip summary-address eigrp 100 4.0.0.0 254.0.0.0 5 leak-map 4and5 ppp multilink ppp multilink links minimum 2 mandatory ppp multilink group 1 max-reserved-bandwidth 100 service-policy output Bandwidth end Thanks guys -Mike _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com -- Regards, Joe Astorino - CCIE #24347 R&S Technical Instructor - IPexpert, Inc.
