Alexei, sorry for my confusion. What I meant by on only one interface is
inbound, Say I have an Internet router and have an acl with log on the
inbound of the internet connection. To me I see no difference between log
and log-input in this scenario.

With all due respect...
'log-input' will log L2 from where the packet has arrived when 'log' will
not. As a side effect if ACL is applied outbound 'log-input' will still say
where the packet had come from, but 'log' will not.
Say router has 3 interfaces E0/0, E0/1 and S0/0. If you create 'log-input'
entry in the ACL which is applied to S0/0 outbound, you will still be able
to say where the packet came from. If you just do 'log' you will loose
visibility to where the packet has arrived from.
Best regards,
Alexei
