what am I doing wrong (src-mac-addr in bridge filter) a bug?

Hi
command
[admin@MikroTik] > int bridge filter add src-mac-address=11:22:33:44:55:66 action=drop
gives me this
invalid value for argument src-mac-address

then I think: I must setup a bridge interface.
but it says the same

tested on 2.9.34, 2.9.38

you have to specify mac-address mask
e.g.

11:22:33:44:55:66/FF:FF:FF:FF:FF:FF

thx! it works

but i don’t know when i try to do this by HyperTerminal i says: invalide value, and when i put this by putty it’s ok

anyway. THX

I’ve already suggested to put default mask /48 if none specified by user, as it is in winbox.
