show mac-address-table not working on ASA5512

I'm unable to excute "show mac-address-table" on an ASA5512, running 9.1(1). The output is: 

asa-test# show mac-address-table
ERROR: % Invalid input detected at '^' marker.

Has the command changed for this model / version? It works fine on ASA5505's running 8.4(5).

Thanks for your time,

Do a 'sh arp' to get a list of known mac to IP mappings.

hi john,

the show mac-address-table command should be valid.

check if you've got MAC learning enabled on the ASA interface using show mac-learn command.

edit: could you post show firewall? the above command works on transparent firewall only.
