U mean to place a class at the end with police to drop packets with highest priority ? Is that the way ?! I have such class but it is not with highest priority... Now I'm certain this is a problem with HTB... I have dumped the snmp traffic and what is seen is that as u know mrtg via crontab makes queries every five minutes... there is 6 queries ... the graphics show problems in the first three graphics and no problems at second third.. what happens is the following : time 0 sec snmp query for interface 1, (nothing is returned) snmp query for interface 1, (nothing is returned) snmp query for interface 1, (nothing is returned) snmp query for interface 1, (nothing is returned) snmp query for interface 1, (nothing is returned) timeout snmp query for interface 2, (nothing is returned) .... five times... timeout snmp query for interface 3, (nothing is returned) .... five times... timeout snmp query for interface 4, (response recieved) snmp query for interface 5, (response recieved) snmp query for interface 6, (response recieved) aprox time passed 27sec i have shaping only on downstream.. So this is ~30sec downstream traffic starvation atleast 5-10 times per hour... it is a real problem !!
