MAC Address - Four Interfaces with the same MAC Address

four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.
but it still works.
what difference does it make to have all macs the same or different?

You should post the full screenshot of the output of your ifconfig command.

Code:
intbe1:         ether 0:20:e0:76:a1:a2 
intbe2: 
        ether 0:20:e0:76:a1:a2 
intbe3: 
        ether 0:20:e0:76:a1:a2


for example all ether mac addresses are the same. should they all be different?

What are these interfaces? That matters. If three interfaces are configured as a bridge, they might share the same MAC.

You should take a screen shot of the full output of ifconfig -a and post the screenshot if you want our help.
