4 Port Serial Interface on 2600 [7:66518]
I note the 4-port serial interface (NM-4T) is not supported on the 2600, but I recall having an older image which did list the interfaces, but I can't recall the image version. Does anyone know what version of IOS will support this module?

RE: bandwidth [7:61552]
I would bundle the two serial interfaces together using Multilink PPP, then place access control on the router so customer's can't talk to each other, then apply rate limiting to each customer with guaranteed 64k, burst additional 64k and do rate limiting on bundle (if that's possible). This is generally what telco's are doing with Metro ethernet switches, except traffic is segregated by either VLAN or MPLS VPN.

Normal traffic despools after telnet queue is empty. If you are sure that there will always be bandwitfh left for other traffic, PQ will do fine. That is one way of using it. During transmission, PQ gives priority queues absolute preferential treatment over low priority queues; important traffic, given the highest priority, always takes precedence over less important traffic. Packets are classified based on user-specified criteria and placed into one of the four output queues-high, medium, normal, and low-based on the assigned priority. Packets that are not classified by priority fall into the normal queue. Figure 7 illustrates this process. Congestion Management Overview http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/qos_c /qcpart2/qcconman.htm Why Use Priority Queueing? PQ provides absolute preferential treatment to high priority traffic, ensuring that mission-critical traffic traversing various WAN links gets priority treatment. In addition, PQ provides a faster response time than do other methods of queueing. Although you can enable priority output queueing for any interface, it is best used for low-bandwidth, congested serial interfaces. Considerations When choosing to use PQ, consider that because lower priority traffic is often denied bandwidth in favor of higher priority traffic, use of PQ could, in the worst case, result in lower priority traffic never being transmitted. To avoid inflicting these conditions on lower priority traffic, you can use traffic shaping or CAR to rate-limit the higher priority traffic. PQ introduces extra overhead that is acceptable for slow interfaces, but may not be acceptable for higher speed interfaces such as Ethernet. With PQ enabled, the system takes longer to switch packets because the packets are classified by the processor card. PQ uses a static configuration and does not adapt to changing network conditions.

RE: FR Low Latency Queuing (LLQ) [7:59820]
This is something I am researching currently. I believe LLQ is CBWFQ+PQ and the PQ is strict. This means that anything above the allocated rate is dropped. This is fine for voice traffic where you reserve say 200kbps for 8 voice calls, and anything more than that is dropped, but not suitable for data applications. You will need to use CBWFQ for your data apps, not place them in the PQ. The CBWFQ will guarantee bandwidth to PC1 as you mention in your first post. I would say that the PQ only gives you 30k due to slow start after packet loss. Finally, why CBWFQ gives you sometimes 100k, sometimes 50k, - I can understand it giving you more than 80k, if there is more available, but I'm not sure why it gave you less. Perhaps the application or operating system applied some congestion control. I believe Win2k or XP does a lot of good work to not hog all of the WAN bandwidth. At this stage, I would question the appropriateness of FTP as an accurate traffic generation tool. As to the ping times, your bandwidth under the priority condition is only guaranteed up to the amount reserved. Anything above that is dropped if the Q is strict. PC1 would get better response if the ping traffic was in the PQ, but it isn't so it is placed in the same Q as all the FTP traffic. Then within the PQ, your ping has to sit at the end of a bunch of FTP data. I wouldn't be surprised if your ping traffic from PC1 was actually worse that PC2. PC2, under CBWFQ, would be more fair to small ping packets than many large FTP packets.

Thanks for the info - I was looking at using the ErlangC model due to the nature of computer networks. Currently, my modelling is based on assuming an application takes 2 seconds to complete a task if it had 32kbps of bandwidth reserved for it, I can use the Erlang model to calculate whether 95% of transactions can be completed within say 2.3 seconds (with the 0.3 seconds being queue delay) - but by changing the bandwidth I change my underlying assumption of 2 seconds. Ie, if I allocate 64kbps, then the application may only takes 1.2 seconds and my model changes accordingly. The traditional Erlang model applies well on a packet-by-packet basis (just like queues of people in the bank, etc), but I'm not sure of its applicability to a series of packets on a whole which make up a transaction.

For the QoS+Multicast exam, I didn't read the Multicast Cisco Press book, only the IP QoS book, plus some whitepapers/documentation - and I struggled - so I would recommend both books.

For those who managed to pass it do you consider a tough or easy going one. Regards,Yasser hi, as far as i remember the passing score was 720. the answer to your second question depends i would say. i found it one of the most difficult exams i had so far. but you can make it. be prepared for deep questions and troubleshooting. hth -bis Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=52512t=52470 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Stuck in rxboot mode on 2524 [7:51780]
We had the same problem last month on an old 4000. The solution, from memory, was to use the config register or boot system command in the conf t global mode. I remember we did o/r 0x2102 and the next boot showed the config reg at 0x2102, but it was still in rxboot mode. I think the next step was within the configuration. Memory a bit rusty - but it may help trigger some ideas.

RE: OT: 2 questions [7:51751]
The real question is how to do all that you mention below AND get paid for it; meaning, what about the other policy development, group meetings, proposal writing, etc, that happen along the way Rik -Original Message- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] Sent: Wednesday, 21 August 2002 4:15 AM To: [EMAIL PROTECTED] Subject: RE: OT: 2 questions [7:51751] [EMAIL PROTECTED] wrote: I have been following this group for some time now and am very impressed by a few of the regular posters and I have some questions for them. How do you get all of your knowledge and information? For example I just read Howard Berkowitz OSPF tutorial from the Certification Zone and it is very very good. I was very impressed at the detail Howard went into the tutorial and his knowledge. The same goes for Pricilla. How do you guys get all your knowledge? You are very sweet to flatter me so. :-) I have learned so much because I have been doing this for over 20 years. I think Howard has been doing it for over 30 years (plus he is a genius! Seriously.) Other tips: Really do read RFCs and IEEE documents. If you want to be like Howard, get involved in the development of RFCs. Read the drafts. Join the mailing lists. Analyze protocol behavior with router show and debug commands, and, of course, with a protocol analyzer. (You knew I would say that!) Don't be afraid to try weird stuff in your lab. Chuck Larrieu can be our inspiration there! ;-) Choose your books carefully. Skip the silly Get rich quick, get Cisco certified books. When trying to decide if you should buy a book (if you have physical access to it, such as in a bookstore), look it over carefully for good writing and technical accuracy. Choose a subject that you know well and see what the author says about it. I choose TCP, for example. If the book makes it sound like all you have to know to understand TCP is that there's a 3-say handshake, I put the book back on the shelf (hopefully hidden so nobody else will buy it either.) Here's a list of the books that I think are the best in our field: http://www.troubleshootingnetworks.com/books.html Priscilla In the tutorial it talked about the Dijkstra algorithm and how Howard is working with a group and changing the route computation. Wow!! Where did you learn to do this? I'm in the process of studying for my CCIE and I want to be an Internetworking Expert. When I think of an expert I think of people like Howard, Pricilla, Jeff Doyle, and I am wondering where can I go to learn all that they know. Do you guys memorize stuff? Because there is so much to learn I wonder how you remember it all. I'm just wondering because I want to be like you guys. I know to be like this it is not easy but I am willing to work at it. Second question is what type of ISDN interface would I need to connect to an ISDN switch? Where can I go to find this information?

I saw some licensing software for the Sup III that was around $1700 for both IP and IPX. I don't know that that is all about. -One 48 port RJ45 blade for servers and workstations on same floor -One 6 port GBIC blade (WS-X4306-GB) that will be used to connect to five WS-2950s on different floors -I will use the WS-5483 GBICs to connect the 2950s to the six port WS-X4306-GB Can anyone think of things I haven't considered?
