LAN is created only by dlink normal switch

Answered Question
Oct 21st, 2008

HI all professionals.

In my company all the network is created by cascading the normal 12 or 24 ports switches.For around 150 computers, is it the right way to create a network. Or we need to change something in this for make it better.

I have this problem too.

Munish,

Ideally no - this is not a good way of doing it, as you are creating 1 very large broadcast domain, which can be counter-productive.

I would suggest you consider actuallu purchasing "Switches" and consider a 3 layer model:-

Access (users connect to this)

|

Distribution (the access layer switches are aggregated here - & possibly some dynamic routing)

|

Core (where everything comes to, perhaps you just have layer 3 interfaces here)

I suggest you read the below design guides to get an idea of what you can do!

Segmentation is your friend, minimize broadcast domains and reduce points of failure. 150 computers cascaded is asking for one big headache.

Much depends on what you mean by "cascading". If you wire the switches with a root switch and as a flat broad tree, not daisy chained, 150 hosts shouldn't normally be an issue. If possible, keep high traffic hosts, e.g. servers, as high in the tree as possible, ideally the root.

If you mean "cascading" with something like a 3750's special stack cable, that's should be okay too.
