Hi.
I have an 8.1-RELEASE (yup, a bit outdated).
Today I saw a situation when I observe a speed about 90 MBit/sec on an
interface where altq is enabled, but root queue shows only half of that
amount.
Here comes the output:
config:
altq on em0 cbq bandwidth 100Mb queue { domru, internal }
queue domru bandwidth 30Mb { domru_voip, domru_term, domru_standard }
queue domru_voip bandwidth 2Mb priority 7 cbq(borrow)
queue domru_term bandwidth 2Mb priority 7 cbq(borrow)
queue domru_standard bandwidth 25Mb priority 4 cbq(red)
queue internal bandwidth 70Mb cbq (default)
pfctl -vvvs queue:

So... It's obvious that this flow doesn't match any of the configured
queues. In this case I expect it to match the default queue. It's clear
that the rate in the default queue is far below 60Mbit/sec.
Does this output means that this flow isn't shaped by the default queue
? Or may be it means that pfctl -vvvs queue doesn't _show_ the packets
that go in the default queue, except on the ones that are explicitely
bound to it (I have such packets, I explicitely sent some traffic to the
deafult queue) ?
Thanks.
Eugene.
