Difference between cisco Switches

[keeran]

What are the difeerences between Nexus, Catalyst, Meraki und Business Switches ?

I couldn't find any useful information on Internet. 

Can anyone explain me ?

Nexus is DC-grade switches.

Catalyst is Enterprise-grade router, switches, WLC and APs

Business Switches are the "economy" grade.  Least amount of features.

Thx for your answers.

What about the performacne aspect of them ?

[Joseph W. Doherty]

That can vary, i.e. overlap, between different series.  For example, a "high end" Catalyst might offer more capacity (which is really what this is about when discussing "performance", as in, wire speed, or line rate, is what all can generally accomplish, just usually a question of how many ports they can run, at that rate, concurrently) than a Nexus.

Generally, Nexus has "more" than a Catalyst, which has more than a SMB switch.  I think (?) the Meraki series falls into the Enterprise level.

Depends on the application.  

Nexus and Catalyst are "top tier" depending on how it is applied in the network.  

Nexus is "the" switch to use in DC environment.  Catalyst is the recommended method for Enterprise network. 

SMB is someone just wants the "Cisco" logo for a network equipment but with a budget of a Netgear/D-Link.

The sweet spot for Meraki is:

• Lean IT Teams
• Those who want integrated cloud-based management without having to deploy Cisco DNAC
• Require L2 or basic L3 (only static and OSPF routing is supported)
