LAN Party Help?

And just after sending that last post, i realized that these routers can link aggregate on ports 3 and 4, so i could have had a 2gb connection between routers and such. Wish I would have remembered that earlier, like during the party lol. But, again it was good enough the way I had set it up.

You’re usually fine for small numbers of people <8.

When you start getting 16+ people on a Lan party, most of which have porn/game/movie/music collections that everyone else wants, you notice the slow down when gaming.

It’s especially fun when one poor bugger gets hit by a whole bunch of people demanding files … their PC comes to a crawl - luckily, since no single PC can saturate a gigabit network interface (valid up until SSD’s came out) then that’s not usually a problem …

It’s when everyone is swapping files, and gaming, at the same time, you notice slowdowns with multiple switches.

Well I had it all firewalled down to pretty much nothing other than the games being passed through without a password only me and my second in command knew, everybody else smart enough to try and crack through, like i said in a post before, respected me enough not to try, or were too busy gaming.
So basically it comes down to lol and no disrespect to any who may read this in the future, but if u have idiots who just know how to play games then I’m pretty sure that the way I set it up was plenty enough power if these were the resources available to them. Wouldn’t you agree?

100Mb/s is more than enough for 16-32x players (and likely upto 100x players) that aren’t file-sharing :wink:

Yea, probably. But, I like to have the extra headroom as it seems like, to me anyways, that it helps frame rates and pings and the likes. Not sure if that is exactly true but that’s what it seems like. Lol, It’s just like once you go gigabit…

[QUOTE=debro;2289237]uckily, since no single PC can saturate a gigabit network interface[/quote] You haven’t seen me make several hundred connections to your windows shares yet. Ah, the joys of seperate file copy transfers.

:bigsmile::bigsmile:

Where are the pictures? Youtube deathmatch videos? Gimme proof! :slight_smile:

There were a few hiccups and very minor stuff but that’s to be expected since you can’t always get everything perfect.
What kind of stuff and hiccups? Always eager to learn how to resolve even small minor network things.

But again, big thank you to you Mr. Belvedere.
You’re most welcome.

That will kill the 2x PC’s involved, but won’t saturate the gigabit switches bandwidth, because even a PCI-E x1 doesn’t have the internal bandwidth required to saturate the network.

Of course, you could always be a complete bastard and get a PCI-E x4 network card, possibly with multiple interfaces … and a few SSD’s …to test the theory, but I’d suggest that’s probably outside the scope of a general friendly ram-shackle Lan-Party & heading towards nerd-ville.

Gotta remember that when i buy new switches :bow:

More like heading to pirate bay ville.

Well, I just felt like coming back and updating you guys on this topic.
I just bought a Cisco Catalyst WS-C2948G from my local high school for $30 as my uncle is the tech admin and they are gradually upgrading everything.
I think I got a little in over my head, but as was previously mentioned a big switch would be better than stringing a bunch of little routers together, I have no idea how to set it up and google is not helping and it has already passed it EoL/EoS so I cannot find much info on how to set this thing up on Cisco’s site either. Google has helped a little as I have found out I don’t think this will do DHCP for me.
So I was thinking, could I hook up just one of the wrt310n’s and use that as my DHCP server, and does anybody know how to configure one of these switches or at least know where to point me to so that I may learn?

  1. Find out how to reset it - I’m assuming the school IT team have configured it different from defaults.

  2. It’s a switch, it doesn’t assign IP addresses, so you you will need either:

  • a PC to assign IP addresses via DHCP if you want more than 252 PC’s.
  • a generic router set to serve out DHCP (for less than 252 PC’s).

There are 254 usable IP addresses in a standard consumer local sub-network - your router with DHCP server is likely to not not handle more, nor hand out more IP addresses ouside of a 192.168.ABC.XYZ subrange, where ‘ABC’ is set (either by manufacturer or you), and not dynamically variable, but XYZ is the range from 1 to 254. The router requires one IP address for itself.

Because this cisco switch is a smart switch, it also uses one of your IP addresses so that you can access the web interface.

Probably don’t mess with any settings you don’t need to :slight_smile:

That first link I stumbled across after I had posted here, and thanks for the second link.
I have also read that I need some sort of adapter to work on the mgt and/or console port so that I can configure it, but I also read that there was some software that would emulate the COM port and such that I need, I cannot seem to find that page again though. So, would I need an adapter or could I just hook an ethernet cable up to one of those ports and configure things that way?

I’d expect that since it has an IP address, you can use the ethernet port to configure the switch, once you’ve assigned the IP address, or set it to get IP via DHCP allocation :wink:

Otherwise you need a serial interface of some sort.

Aaaargh!
This is why there is a need for network engineers :wink:

Welcome back! Still eager to see some pictures of that lan party of yours.

Try using the Cisco Network Assistant. It can probably connect to your new (old) Catalyst and you can set it up from there. Doesn’t matter which port you use to connect to it unless someone really hardened down the configuration. Your uncle should be familiar with this tool.

You probably already have to connect a game server, so make that one a dhcp server as well and you will not require any router whatsoever.

If you have the hardware you can set various server operating systems in one big free virtual server system.

I don’t really know how to use CNA, it’s a little confusing, the getting started guide and the help pages don’t help much. Also, I have been messing with CNA and stumble across the community thing and automatically discovering devices but I am willing to bet that my uncle has turn of the CDP and it won’t even get an IP address from a spare wrt54g I have so that I can access it anyways. I see that there is a resetting section in the links provided but they do not apply to my switch and I have no idea how to reset it.
I think I may need a serial adapter for it to do anything and eBay has turned up a few results, which one would work for me?
This one?
Or this one?
I have also realized that port 11 or so is also a 10mb port, so I’m thinking it may also be a mgt port, as I have been reading, but won’t do much good as I cannot access anything.

Also, I personally didn’t take any pictures of the LAN party, but I can try and find other people who may have for you Mr. Belvedere.

Well, I just decided to buy a different adapter. I think the adapter may be wired wrong as I seem to be having a problem with accessing anything. I have set all the proper settings, 9600 baud, 8 data, 1 stop, no parity, no flow control, then I connect the cable to a friends serial port, as I not surprisingly I don’t have any when I need them lol, and then plug in the switch and just sit there watching hyperterminal as nothing shows up.

I took the adapter housing apart to see which wires ran where and I cannot for the life of me figure out if it is right or wrong, for clarification, what pin number is the far left if you are looking at the back side of an rj45 socket? If it helps the far left pin is on the upper row.

I have looked through all the literature I have found and I cannot figure out a way to reset this thing either, mainly because their is nothing about my specific switch. The link for the 2940 said something about a mode switch, this thing unfortunately does not have any switch at all. I really wish I did not waste $30 on a switch that I am never going to be able to use.

Perhaps it’s better to ask Uncle to make a normal decent configuration of that thing. It will be much quicker than toying with not-working com ports.

I’ll try to see if he can, but it was installed and running before he was tech admin so I don’t know if he would know the previous settings and such.
