show mac-address-table not working on ASA5512

Hi,

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,

John

Hi John,

I am actually surprised that there is anything like show mac-address-table on an ASA box, as this command is more common on switches that maintain the MAC-to-switchport table. Did you perhaps mean show arp instead?

Best regards,
Peter

Ah, Peter, the smaller

Ah, Peter, the smaller ASA5505 contains a built-in switch that the ASA5512 does not - "show mac-address-table" must be querying that. 

Thanks for your help,

Hi,

this command would indeed work on another ASA platform if this firewall was in transparent mode.

As you said the ASA 5505 is a little bit special because the interfaces are L2 switchports and so this command is also working in routed mode on this platform.

Alain
