Hello Everyone, I'll be leaving the list now. Maybe be back when I am more motivated. Just note to everyone that while I did learn a lot here, the most valuable thing I learned was to look it up myself before asking for help. Good Luck and Don't forget the blueberries.

Hello Everyone, Kinda tricky question about ethernet. Is the correct conversion; PPS * 704 = BPS or PPS * 672 = BPS 64 byte frame including CRC + 8bytes [preamble] + 20bytes [interframe] = 84 bytes 84 * 8 = 672 672 - 704 = 32 bits = 4 bytes. 704 popped into my head and I can't figure out why. Am I forgetting 4 bytes or am I remembering what the blueberries told me?

RE: Hub-to-Switch connection problem
The problem you are facing isn't osi layers. Its pinouts. The pinouts for 10/100 ethernet are 1,2,3,and 6. 1 and 2 are tx and 3 and 6 are rx on some devices such as switches, hubs, routers. and 3 and 6 are tx on other devices, like nics. you use a crossover cable to connect tx to rx. tell me if this helps. larry p.s. i might be backwards but the idea is the same. -Original Message- From: analogkid01 [mailto:[EMAIL PROTECTED]] Sent: Friday, December 01, 2000 4:31 AM To: cisco Cc: analogkid01 Subject: Hub-to-Switch connection problem Okay gang, I had an interesting and annoying situation yesterday morning, and I'd like to see if anyone else has had an experience like this: My client was installing an older BayStack 301 switch into their existing network, which consisted of a Bay Access Node router, as well as four stacked SynOptics LattisHubs. The router was experiencing excessive collisions, hence the installation of the switch. So we installed the switch and cabled the router to it, moved all the "power users" directly onto the switch, and left the other users attached to the hub. We attached the hub to the switch via a straight-through cable. The users who were directly connected to the switch had no problem accessing the network and Internet. The users on the hub were dead in the water. We tried swapping out the cable between the hub and switch, tried plugging either end into different ports, tried flipping the MDI/MDI-X switch, and nothing worked. The only thing that *did* work was using a *crossover* cable between the hub and the switch. Now, the rule (which I gleaned from this newsgroup, btw) is that when you're connecting devices at different OSI layers, you use a straight-through - e.g. PC to hub, PC to switch, switch to router, hub to switch - that's all straight-through. You use a crossover when you're connecting devices at the same OSI layer - router to router, switch to switch, hub to hub, PC to PC. In the situation yesterday, a straight-through seemed logical, as we were trying to connect a hub to a switch. Am I wrong here? Why did the crossover work? Thanks, BJ P.S. sorry for the Bay-centric example...I'm trying to get them to change that. ;-) _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Cisco 761M connecting to ISP using public ip
Pretty sure Cory, PAT, is just NAT with overload essentially... I have a really cool NAT/PAT issue that i've been working on. I'll draw it up and post it later. Lets just say that we want to PAT everyone to 1(legal) address, then we wanted to static translate just one machine (illegal addresss), to a legal address. When we made this static translation... this would be considered NAT. also if we wanted to translate 5 machines(illegal) to 5 (legal) address this would be NAT. but if we wanted to translate 5 (illegal) addresses to 4 (legal) address this would be PAT. anyone not agree? please write me so i'm not wrong in the future :) larry(fat) On 24 May 00, at 8:26, Stull, Cory wrote: > Larry, > > Are you sure about the static translations thing on the 761??

Re: Cisco 761M connecting to ISP using public ip
hello ajiemher, If you read the rules of this mailing list, one of the things NOT to do is start a message with "one of my customers".. but I would use the registered ip's and let him be. If you want to use pat, thats great, just use static translations for his exchange server. http://www.cisco.com/warp/customer/701/60.html good luck, larry On 24 May 00, at 0:39, Ajiemher wrote: > Hello, > > One customer of ours will be using cisco 761M router to connect to the > internet.

router throughput test software
Hey Everyone, What I'm looking for is a way to have a current throughput status of all of my ports. (constantly) . I couldn't really find what I was looking for in the archives. Any ideas ? Secondly, does cisco have a mib file? I've been in and out of the cisco web site with nothing but a paper trail leading me back to rfc 1213 but no actual file. I understand that there will be dif. mibs for switches and routers.. but still no file. :) thanks for the advice larry Larry Averitt, CCNA Design Validation www.imcnetworks.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]
