"netstat -I <interface>" should do the job

It does not work as netstat works over TCP/IP, not over SNA

netstat -v will give the "BURNED IN" MAC address for all your adapters.
However, programs like HACMP can do MAC address swapping and thus the
burned in MAC address might not be the one currently in use. Use
netstat -i for the inuse MAC address. The MAC address is the one
displayed in the "Link" line. All values between "."s are 2 digits
even though netstat might show only one. Add a leading 0 if necessary
to get the proper 2 digit value.

Or you could also use lscfg to display the physical hardware of the
adapter. The Network Address (MAC) should be listed.

lscfg -vl entX

netstat -v
lscfg -v -l entX
shows the burned in address on most adapters (not all)
lsattr -E -l entX
shows the UAA (Universally Administered Address) if used
snaadmin -d query_port | grep mac

There's a third approach:

# entstat <enet interface>|grep "Hardware Address"|awk '{print $3}'
