Hi Ajai,

I don't believe there is a difference as such.  CAM simply refers to the way the switch uses memory (in a content-addresable) manner to look up the MAC address to port association.

Hope to Help !!

Not a big difference. A switch switches Ethernet frames by keeping a table of what MAC  addresses have been seen on what switch port. The switch uses this table  to determine where to send all future frames that it receives. In Cisco  terminology, this MAC table is called the CAM table (content addressable  memory).

Hi Ajai,

In addition to the nice replies by other friends here, a "MAC table" tells you what data does the table hold, in this case, MAC addresses. A "CAM table" tells you what is the technical nature of this table - a content-addressable memory, or a cache, that performs parallel and fast lookups.

So the MAC table refers to the content while the CAM table refers to the organization and principle of operation. A CAM table may hold many different kinds of data.

in Cisco world the 2 terms are interchangeable as the MAC table is contained in the CAM as all the gentlemen above nicely explained already.

They are actually the same

They are actually the same but in CAM table you can see more in the output.
CAM (content-addressable memory) is Cisco's fancy word.
My teacher always used them interchangeably.
I hope this can be informative for you.
