How do I get a list of MAC address, including ones that do not have IP addresses bound?

How do I get a list of MAC address, including ones that do not have IP addresses bound?

ifconfig appears to only return MAC address if they have IP addresses. I need to get all of the MAC addresses, regardless of whether or not are bound.

In Windows, this is easily done with the getmac, but I have not been able to find the UNIX/Linux equivalent.

ip a
Mister_TogAuthor Commented:
ip a appears to just return address that have IP addresses, like ifconfig -a. I need to return ethernet addresses that do not have an IP address bound.
farzanjCommented:
Well, it always showed me all the MAC.

How about this?
ip maddr show

Which OS are you running?  Both ip a and ifconfig -a show interfaces that do not have an IP assigned on RHEL -- note eth1 in the following example.  Issuing just ifconfig without the -a however will only show interfaces that are up.

It looks like you are right, ifconfig -a works. I should not that "ip a" doesn't seem to work on Solaris.
