RE: Confused (was Re: is this statement true ??)
Yes, makes sense. This means if you have a host connected to a switch with half duplex configuration the contention on the media will be only between the host and the switch port (the data coming/going to the switch). sense ? Thanks On Tue, 26 Dec 2000 19:26:56 -0500, Bowen, Shawn wrote: Yup, makes sense. I can only speak for 3Com on this one, but I believe Cisco implements similar features. On a 3Com Corebuilder (as well as their Workgroup Switches) they use fake collisions as a flow control mechanism. In other words if there was contention at the server or switch and they couldn't handle the load then a collision (a JAM) will be sent. Now, that said after we all just agreed that collisions can not happen on a full duplex Ethernet segment:) If you notice in Cisco texts that Collision Detection is disabled on full duplex links, this is not true. Collision detection is still there, at least on a 5000 and can be simulated by loading up a server at 10MB FD with a few 100MB FD clients on the other end of the Cat, you will see this in action. 3Com does the same thing, I thought this was kinda interesting.

I think what John is getting at is that there is still contention. In his example with two clients trying to reach one server, there's contention at the switch, and at the server possibly. There's no contention on the medium itself. There's only one device trying to send at any one time. The switch has its transmit pair and the server has its own transmit pair. If the switch has two frames to send to the server, the backup happens at the switch. Does that make sense? Priscilla At 08:33 AM 12/26/00, Andy Walden wrote: This is correct. You don't use full duplex if you are competing for bandwidth, ie, plugged into a hub.

Re: HELP! ISDN DDR
Take it this way, With dialer profiles, the logical and physical configuration are dynamically bound to each other on a per-call basis, which allows physical interfaces to dynamically take on different characteristics based on incoming or outgoing call requirements. Lets go back to our practical situation. on the HUB side (Corp router) you need to receive calls from more that one spoke, then you need to apply profiles. On the sopke side (remote) you will call just one place which is the Corp, so there is no need for profiles here.

The following IP addresses can be summaried by which bit of the 3rd octet 172.16.0.0, 172.16.64.0, 172.16.128.0, 172.16.192.0 --- 1st bit, first 2 bit, first 4 bit, last 6 bit I don't think that the following addresses could be summarized on any bit of the 3rd octet. If you have a look to the 3rd octet 172.16.0.0 --- 172.16..0 172.16.64.0 --- 172.16.0100.0 172.16.128.0--- 172.16.1000.0 172.16.192.0--- 172.16.1100.0 Could someone verify this with me guys ?

Re: what is wire-speed?
What do you mean by interfame gap? is it the address? What about ingress and egress issue? how do they calculate it? Thanks a lot Bye On Sun, 10 Sep 2000 19:41:13 -0700, Priscilla Oppenheimer wrote: Wire speed means the switch can pump out packets as fast as the medium can handle. For example, the maximum packets-per-second rate on 10-Mbps Ethernet with 64-byte packets is 14,880 packets per second. This comes from Preamble = 64 bits 64 Byte frame = 512 bits Interframe gap = 96 bits Total = 672 bits Max packets per second on 10 Mbps Ethernet = 10,000,000 / 672 = 14,880 packets per second. A wire-speed switch, which most are, would have no problem outputting that number of packets per second. If you were to use 1024 byte packets, the number is 1197 packets per second on 10Mbps Ethernet. So, yes, vendors do tend to use 64-byte packets when quoting their results, because it gives them better numbers. The other thing vendors do is quote the results when using Gigabit Ethernet. That's where numbers like millions of packets per second come from. In addition, if the vendor's numbers are based on tests that output to multiple ports, then you can get astronomical numbers, for example, 1.48 million packets per second multiplied by 100 ports. As you can probably guess, this is a rudimentary way of specifying the performance of a switch that is fraught with the over-zealousness of marketing drones. ;-) Priscilla At 02:12 PM 9/10/00, Kent wrote: Hi all, Any body knows what they mean by saying "wire-speed" forwarding about a switch? Also, when Cisco says a switch can forward at 100 million pps or something like this, what the size of the packets they usually refer to of the PPS(packet per second)? 64byte?

Re: Off topic Nortel Certifications
Guys, Thanks a lot for the useful information, you have been very hepful. Howard, Chuck, and just to close this issue. I don't wanna to discuss it any more. You could answere me with a better way. The point that I want to clairfy is if you don't like the question you don't have to answere just ignore it. Not all people are on the same techincal level. Let me tell you something more, the technicality is never a problem you can search and look and you will find the answere, the point is on people's attitudes. I didn't not write any books I don't have the technical skills maybe of both of you but I can gain it, it is just a matter of time and at least I know how to talk to people politly. And no Howard, I didn't want Cisco's analysis of Nortel exams? but unfortunatly this was your answere.Look to how others answered my concern they didn't do a SHOW. Anyway thanx guys for the answeres.

There is no specific exam for the Nortel NNCDS. Rather you need to do one of the core technology exam for the NNCSS and then do the Nortel web based exams from home ( or elsewhere) to fullfill the other requirements. See http://www12.nortelnetworks.com/training2/certification/nncds.html for more info. The Nortel design exam is for the next level of certification, the NNCDE ( design expert). To get that you need to do the NNCDS, plus: one advanced exam, one more core technology exam and the design exam. See http://www12.nortelnetworks.com/training2/certification/nncde.html for more info on that one. So if you mean you were planning to write the design expert exam 920-021 ( Network Design Essentials for Routers and Switches) you would not be certified as anything. Just a heads up.

Does anybody have informations about Nortel certification NNCDS. Number of questions, how long the exam is ... I am gonna take the eam very soon. Thanx Not speaking officially for Nortel here, but I have been involved in developing one certification exam so far, although the particular product was cancelled. I am involved in internal conversations about the direction and value of certifications. At least for the one that I worked on, which was product-oriented (that may change) and a first-level design certification for carrier presales, the majority of people that wrote and discussed questions were definitely technical. There was an education/certification manager concerned with quality, a tech writer, and about six or so experts including presales SEs, postsales support at a very senior level (think Cisco NSA with some research of their own), and product architecture (me). I've informally discussed with Paul, and started to bring up in Nortel, the idea of adding a Nortel track to the site. Nothing definite yet, but I certainly would like to assess the level of interest. Design certifications at Nortel, especially the third-level architect, are rather different than Cisco's model. They rely less on computer-administered exams and more on a model such as that of medical specialty certification -- presenting case studies of real networks you have built, and then an open-book design that will be evaluated by a panel of experts. I can't get into too much detail, but Nortel is working internally to make its certification process even smoother. It does appear that there's a corporate style of helping the certification candidate, not tormenting them unnecessarily.

Re: Frame-relay traffic shaping question
As far as I know, they are both equal. So you can do it by either way.
Please someone correct.

Wizards,
As the FRTS has been brought up here, I really want to
take this chances to get some help from you in
understanding this.
When we enable the 'frame-relay traffice shaping'
under the inferface, we start using frame-relay
traffice shaping not generic shaping, right?
in the map-class of frame relay, we can configure CIR,
Bc and Be, how is this different from just configure
'traffic-rate xx yy' in the map-class?
As far as I understand, it is not quite effective to
controll QoS in FR, I am not sure whether someones
have seen some detailed perfermence comparation betwee
two kinds of traffic shaping.

The easiest way to do this is to only configure the

Example commands -

BECNs (not foresight)
for for
thottling
If you set XXX to 512K and YYY to port speed, he
will transmit at port
speed unless he receives BECNs from the network, and
then he will throttle
down to 512K.
If you set both XXX and YYY to 512K he will always
transmit at 512K
Depending on your service provider and how
congested their network is you
may be able to go in and buy a small CIR like 64K
and then ignore that and
have your router set to send at 512K. If you do
that and some time in
future your SP starts dropping packets (because they
are over CIR) you will
have to go to them and buy up your contracted CIR,
but until then you can
save some money. We've been running ATT Frame
Relay for a couple of years
and have yet to receive a single BECN.
It is possible to go in and specify mincir, Bc,
Be, etc. But unless you
are going VOFR or some other application that has
specific needs using
generic FRTS will cover just about everything.
Hope that helps,
Mike
Guys,
What are the parameters that I should configure on
the router to control
the
bandwidth usage of the user on a frame-relay
configuration.
For instance, the user has T1 line and I need to
provide him only 512k. Is
it the CIR, BE, BC, MINCIR, and traffic rate only ?
and how do I calculate them ?
