Re: [LARTC] CBQ Rate
And different prio's in the filter statement will not change much. It only determines the order the filters are checked. But wasn't there a bug in 'tc' that would delete all your filters that had the same prio, when you only wanted to delete one of them? -- Damjan Georgievski jabberID: [EMAIL PROTECTED] ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

But take weight = rate / 10 as a general rule. And your bandwidth parameter should be the real NIC bandwidth. So 10mbit. And it's also better to create a parent class attached to the root qdisc. And different prio's in the filter statement will not change much. It only determines the order the filters are checked.
