Collisions on Ethernet Lan
Hi, HOw do I reduce the collisions on the ethernet LAN. I am using a cisco 2600 router with an ethernet port My switch is CATALYST 1900 series.

Re: Collisions on Ethernet Lan
Are you having an excessive number of collisions? Why are you trying to reduce them? Collisions are there by design. Off the top of my head I forget what percentage of collisions is considered "Bad", but I believe it was 20%. Someone will correct me if I'm wrong on that. Unless you are seeing more than that or it's causing noticable performance problems, don't worry about it. > Hi, > HOw do I reduce the collisions on the ethernet > LAN. > I am using a cisco 2600 router with an ethernet > port > My switch is CATALYST 1900 series. > > Please help me. > > regards > Raj > > - > This mail sent through http://www.sify.com > > ___ > UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html > FAQ, list archives, and subscription info: http://www.groupstudy.com > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] ___ Say Bye to Slow Internet! http://www.home.com/xinbox/signup.html ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Collisions on Ethernet Lan
You're right! I was thinking of broadcasts, which shouldn't exceed 20%. I think 0.1 % is a little low, though. The collision rate can be fairly high before you'll notice much of a degradation in performance. I just took a look at a fairly busy ethernet port on our main router and it was showing a 4.4% collision rate. I personally wouldn't get worried unless the rate was pushing 10%. > 20% is way too much man .. i think its 0.1 % > > -Original Message- > From: John Neiberger <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED] <[EMAIL PROTECTED]> > Date: Wednesday, August 30, 2000 7:36 PM > Subject: Re: Collisions on Ethernet Lan > > > >Are you having an excessive number of collisions?

RE: Collisions on Ethernet Lan
You shouldn't have any (or very little) collisions on a switch, it is by definition a point to point virtual circuit. Since there are only two nodes, it is unlikely that they will transmit at the same time. I would use Full Duplex if you can, then you CAN NOT have collisions by definition. Nor should you see that many CRC's, runts, fragments, giants or other such crap. If the switch is in cut-through mode then it will spew crc's, runts, and everything out through all the interfaces that the traffic is destined for. I agree that collisions are a part of standard Ethernet, but not for Full Duplex Ethernet. The only time you will see collisions on full duplex links is from certain OS's (Netware to mention one), and they use them illegally for back off flow control, this is not part of the Ethernet Spec and is a kluge.

Normally , if the collisions on the Ethernet segment are 10% of the total traffic flowing on the segment,then thats not considrered bad.

RE: Collisions on Ethernet Lan
There are too many unknown values to say that .01% collision rate or 10% collision rate is "unacceptable". What is the distance between the switch and the workstation, what is the average packet size, what is the utilization level of the line . Cisco may state that .01% is correct and that is what you should use on the test, but in the real word you cannot assign an arbitrary number and say it is bad, unless it is 100% of course. There have been tests done where Ethernet runs fine at 60% collisions, but that was in a controlled environment. Collisions by their nature are not bad that is how Ethernet works. One of the easiest ways to determine if you have too many collisions is "Is the performance deteriorating". And you have your network baselined you can always go against the baseline. Just some thoughts.

RE: Collisions on Ethernet Lan
Anybody who states an exact threshold for a high rate of Ethernet collisions, without any reference to the network topology, applications, and measuring method, is speaking without authority. &;-) I think that the 0.1% that Cisco likes to claim is based on the comparison of frames output by the router to all collisions seen on the segment. Two things to keep in mind: 1) This compares just one station's output rate to the collision rate, and 2) a router generally prefers better performance than a generic end station. I once heard Radia Perlman say, "Do you know how to tell when an engineer is lying? When he or she uses the word 'always'". Be careful of "rules" and "checklists." Although I have checklists in my book, I hope people read all the caveats and explanations that go with them.
