Do we really need 16K mac address table?

[Deepak Kumar]

Hi,

I am busy reading a book for my magic number. Volume one this book has left a question. Do you we really need a 16K mac address table in small or enterprises level switching?

Looking for your opinion. 

Regards,

Hello,

I guess not. Switch specs, like most anything else, give you an upper limit, mainly to make potential buyers aware of the capabilities. It is probably similar to MS Word: according to Microsoft, most users only use 10 percent of what is possible, the rest is never used.

 I will agree @Georg Pauwen , most of the cases we do not need that many, but most of the products when we compare it sales pitch(example my case i got iphone i do not use 100% features but we need all of them available when we buy).

May be Cisco have some use case these kind of requirement when they design and writing code, so lab tested done with that requirement.
