unfortunately, you are right..I have the same problem but since I use mikrotik products, nobody from their team realy cares to add features that most of us need them. They have no support on forum. SwOs looks like the Dude, dead.
Please implement snmp v2c and 64-bit counters on the RB260GS.
These are gigabit ports and 32-bit counters can get quickly overrun under high traffic.
