The budget I have been given from my manager, would not pay for a family visit to McDonalds. However, this is the requirment (my product selection is below) * Provide up to 200 ports on the floor * 2 level building, with multi-mode fibre between level 1 2 * Level 1, has 70 users, 30 servers * Level 2 has 60 users * 2 subnets will be used in this office I suggested, that we use a single 4003 as the core, purchase a Sup III, 1 x 8 port GBIC module, 1 x 48 port 10/100/1000 module. We then use the GBIC's to extend to the 2 x 2950's on the floor above, and 2 x copper GBIC's to the 2950's on the same floor as the core switch. This solution, worked out to be around $100K AUD (australian $$). This was seen as far to expensive. Is there any other model of Cisco catalyst switch that can perform layer 3 routing, GBIC between floors and etc that could do the job of the 4003/4006 ? Or is there a better way of doing it ?

That' right... But for me any reliability value less than 255/255 is a line problem.. check the cables and connectors..

The client cannot accept it as fast as the server can put out. Having a slower line to the client in effect will cause degradation at the server. I have a better answer and question than my previous wisecrack. :-) I also bumped the conversation to the top of the Web site. Answer: The problem won't be the client not keeping up. The problem will occur at a store-and-forward switch between the server and client. (To connect 100-Mbps to 10-Mbps requires a store-and-forward device. Let's say it's a switch.) So, the engineering question becomes, at what point will this mythical store-and-forward switch start dropping packets? Here's a hypothetical scenario: The server has a 100-Mbps NIC. It is connected to the switch. The client has a 10-Mbps NIC. It is also connected to the switch. The switch has 1000 buffers. Each buffer holds a 100-byte packet. The server is sending 100,000 packets per second as fast as it can (i.e. with no significant gap between the packets). Each packet is 100 bytes. The switch is sending the packets out the 10-Mbps port as fast as it can. After how many packets sent by the server will the switch start dropping packets? A free book to anyone who gets the right answer!

[7:65077] Scott, I think you have a great point, it seems that most of the computer technologies we have today are not taken full advantage of. However instead of taking the air out the sale's staff sales as it were ( no pun intended ). Why not suggest upgrade from the Idf's to the server farm. You could suggest Ether Channel to combine some of the runs you have put in ( I'm sure ) when you are upgrading your networks. This way you have more bandwidth to the server farm and fault tolerance. WOW now that's a selling point. Also it can be done with out raising up the costs on hardware to much. You can get duel interface NIC's for your servers that are fairly reasonable now. I am amazed at the push for processor speed now, I can think if very few people that NEED 3Ghz with 2Gb of RAM. However no one NEEDS a Jaguar eigther, some people just want it and if they can afford it so be it. Look at the situation this way at least if your going for over kill the network will perform well, that is better than underselling and then having your clients be upset because they are limited in the future. But hay that's just my 2 cents. Take it with a grain of salt. = ) Steven Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=65274t=65263 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

A lot of them don't. I think EtherPeek does in its latest software. Network Associates does a good job with EIGRP. I'll span a the port connecting out WAN router to the core switch (I'm 99% sure we're getting hit with updates from the WAN). We use NA, but haven't had the need to use it for EIGRP.. You can turn the router into a troubleshooting tool with the various debug commands, of course. There's quite a few for EIGRP and at least one would give you the info that you seek, (probably debug eigrp packet). But, you didn't want to use debugging, for good reason probably. Yeah we don't take debugging on the core routers/switches to easily =) Ever since a new guy decided to debug EIGRP in an EIGRP storm without a no logging console. Thanks!
