LinkSys Switch Comparison

By maxwell edison ·
I’m going to replace a bad LinkSys 24 port hub (EtherFast 10/100 Auto-Sensing, Model No. EFAH24) with a new switch instead of a new hub. Since I’ve had relatively good performance with LinkSys, and the rest of the hubs and switches on the LAN are LinkSys, I’m leaning towards staying with that brand. The switches I’m considering are the following:

EtherFast? II 10/100 Managed 24-Port Gigabit Switch, Model EG24M
(No uplink ports)

EtherFast Dual Gigabit with 24-Port 10/100 Switch, Model EF24G2
(This does have uplink ports as well)

EtherFast? II 10/100 24-port Switch, Model EF2S24
(No uplink ports)

Are there any opinions on these switches and the differences between them? Is there another one I should consider? What are the merits of using a switch instead of a hub?

They will connect clients (no servers) on a 50+ station LAN.

This is a good start:

I've always operated under the axiom that you upgrade software but replace hardware, so get the most hardware your budget allows. Today you might not have the need for gigabit uplinks but tomorrow you might need it for a NAS box or some other bandwidth hog. But I don't think you will get full duplex unless you are linked by fiber.

The primary merits of using a switch vs. a hub is that your 24 ports will no long DIVIDE the maximum bandwidth amongst themselves.

Switches allow maximum theoretical bandwidth of (speed of switch x ports (x 2 if full duplex))

The the max theo.bandwidth with

Before:

Hub Scenario:

The max you will ever see on a Hub is 100Mbps and that's only with one port active - if two are then divided it by two and so on...

I can give you more details if you need them but it gets jargony asto just why switches and hubs can handle things at different speeds.

100Mbps/24 = 4.166Mbps = at full load without overhead what the max the hub could handle

Switch Scenario:

100Mbpsx24 = 2.4Gbps and that's at half duplex

Every port can use 100Mbps of thruput (provided it can be 'fed' that fast).

Of course it depends on what data is going where how fast things go - but the point is that you will see vastly improved performance with a switch vs. a Hub at a really negligible price increase.

This above all else should be enough evidence to show you the meritts of switches vs. hubs.

Heck - it's like $44.99 at Bestbuy for a 5port Linksys Switch for your house - I have three of them. And they perform darn well.

Hope thishelps.

Hi Maxwell,
I just upgraded all my hubs to switches. I heard opinions both ways. So, off to the net for some research. In a nutshell, this is my wisdom. Because switch prices have come down, most companies are moving to switches. This is because itends collisions on the network, improving throughput, thus increasing bandwith. A VERY smart switch, with enough memory, will remember routes through the network(i.e. PC to server), increasing performance.

The Intel site had some very good white papers on the subject. There,I learned that switches have a small latency or lag problem, holding the packet while it determines the route, and locking out the other ports while that packet is sent,(no collisions, right?).

I got bored and skippedto the summary. The conclusion was: If you have a small network, 4 or less PC's, a hub is faster(no lag). If you have a network (or connections, I guess) of 8, switch and hub performance is about the same. More than 8, a switch will improve performance.

I have no real experience with Linksys, so I can't advise you on that. I replaced all my hubs with cheap, unmanaged 3Com switches. A consultant said I should go with managed, but on my 50 user network, I didn't think I need that. I did get the get the fast ethernet port so that down the road, if I want, I can get faster throughput to the server.

Thanks for your great answers, and i hope that helps.
