Please give any clear idea on this?

Hi Senthil,


The generic widely used term multilayer switch means a switch that can do layer 2 and/or layer 3 switching on the same platform. This definition is used interchangeably with layer 3.However, multilayer switch is also used to describe switches which can make decisions on informnation in layer 4-7 as well.


Switches That forward  frames based on Layer 3 and 4 information contained in packets. This is known as multilayer switching (MLS).


A multilayer switch can have ports configured as layer 2 or layer 3. And is capable of routing packets between networks (VLANs).  A layer 3 switch is basically a router (albilty to have ery fast and with a bunch of ports).


layer 3 means its capable of routing between vlans and able to join eigrp, rip and things. you can make any of the ports on the switch a routed port. this means you can use a layer3 switch exclusively as a router if you wanted to.


Hope to help !!

Dear Ganesh,


Thanks for your reply to this post..Can we perform Layer 4-7 information in  Layer 3 Switch?(Little bit doubt)


Tks&Rgds

Hi Senthil,


As i Already told you Layer 3 switches is a high-performance device for network routing,The hardware inside a Layer 3 switch merges that of traditional switches and routers, replacing some of a router's software logic with hardware to offer better performance in some situations.


Some switches can use up to OSI layer 7 packet information; they are called layer 4-7 switches, content-switches, content services switches, web-switches or application-switches.


Hope to Help !!

I completly agree with what ganesh said. It actually depends on the switch you have and it varies b/w different models.
