$ echo 'queue foo on em0 default bandwidth 4294967295'|pfctl -nvf - queue foo on em0 bandwidth 4294967295 default $ echo 'queue foo on em0 default bandwidth 4294967296'|pfctl -nvf - stdin:1: bandwidth number too big ... Though if specified in other units, it wraps around: $ echo 'queue foo on em0 default bandwidth 4.3G'|pfctl -nvf - queue foo on em0 bandwidth 5032704 default
