Hi,
The solution should look like
!
ip access-list logging interval 2000
ip access-list log-update threshold 10
!
cause the intervall is measured in milliseconds
Rack1R4(config)#ip access-list logging interval ?
<0-2147483647> Access list logging interval (milliseconds)
The funny thing: I couldn't find this command in the command reference on the cisco web site. You may find only product bulletins which has some words about the `ip access-list logging interval interval-in-ms command` command.
Regards
Ueli
