What 2.3 version were you running?

2.3.8 should be doing the same as 3.2, here is the 2.3.8 code that does it:

# This routine parses "show controllers"
sub ShowContAll {

    # ...

    while (<INPUT>) {
        if (/^Interface ([^ \n(]*)/) { $INT = "$1, "; next; }
        # ...
        /^Hardware is (.*)/ &&
            ProcessHistory("INT","","","!Interface: $INT$1\n") && next;

# ...



Possibly you were running a 2.3 that did not have that code?
