You need UBB code help too

I was getting there !!!! Went away two seconds to edit the post and you replied

Ian,

Do you have a budget? Personally, I'd just stick in a 24-port Gigabit switch and have Gigabit cards in the PC's. We have some Cisco Catalyst 2900XL switches at work; they ain't that expensive (about £800 from Dabs).

Depends really if you want a simple solution for a few hundred quid ... or not.

I am too tired to be reading all of that, just giving you a cheaper alternative to Ozzy's suggestion, but if the number of machines is low that need good bandwidth between them, then look at a smaller Gigabit solution, such as one of the Netgear 4 or 8 port Gigabit switches. Retail for under £300, certainly for the 4 port and quite possibly for the 8 port too. Look around and you can get some gbit cards for non stupid money too. Rated fine on CAT 5E cabling so

Cheers,

I have an 8 port 10/100 switch at home from Dabs for £25 which works perfectly. I use Top end cisco stuff @ work costing over £100K.

Pick a figure in between and we can spend it for you

Seriously, this a work thing, so budget isn't a problem. All I have to ensure is that all traffic passing between PC1, 2 and 3 doesn't get out and swamp the main LAN.

You need to run VLANS ......!

Run IP as the protocol with an intelligent switch.

No broadcast traffic & as its W2K permissions etc can be set up so that no-one unauthorised can connect.

Hi All,

Need some network hardware help plus networking software config help.

OK, I need to connect three machine together and the network has to run at 100Mbps (lots of big files moving between the three boxes). I also want these three boxes to connect to the main network (which is 10mbps). See diagram below:



Now, all the traffic between PC1, 2 and 3 needs to stay within the 100Mbps network, i.e. behind the box marked with ????? marks.

However, connections further afield need to get through as do incoming connections from other machines on the 10Mbps main network.

The three PCs in question already have 100Mbps network cards but what hardware do I need at ????? and what do you recommend ?

Also, how would I configure the three PCs to work this way. All three PCs are Windows 2K Pro boxes.

Thanks in advance for any advice here.

Cheers

Ian

As above, you can achieve this with a single 10/100 switch (not a hub as they re-transmit packets to ALL ports). The switch will only transmit data destined to a machine attached to certain ports. The switch builds a list of the physical MAC addresses of devices to know what's attached to what.

You would need to configure the OS to stop broadcasting packets going across to the other LAN.

A more technical method is to use a more expensive (manageable) switch that can allow you to implement bridging or routing.

My only experience is with the high-end Cisco and Enterasys switches (£100K+). You can define individual networks across ports using lots of different methods.

Bridging would achieve this, but that uses physical MAC addresses. Routing is based on network addresses, like IP or IPX addresses. There's also VLAN's (Virtual LAN's) where you can assign network addresses to certain physical switched ports, then configure routing on the switch.

If PC1, PC2 or PC3 is only taking to the local IP network addresses, then there's no reason why data should get passed onto another network (unless it's all the broadcasting cr@p).
