Alexey,
I think there is a small bug in tc from iproute2-2.2.4-now-ss990417,
which makes impossible to set the priomap parameter of the prio qdisc.
The patch is as follows:
diff -ur iproute2-2.2.4-now-ss990417/tc/q_prio.c iproute2/tc/q_prio.c
--- iproute2-2.2.4-now-ss990417/tc/q_prio.c Sat May 9 18:46:58 1998
+++ iproute2/tc/q_prio.c Mon May 24 16:26:12 1999

+ if (!pmap_mode) {
for (idx=0; idx < TC_PRIO_MAX; idx++)
opt.priomap[idx] = opt.priomap[TC_PRIO_BESTEFFORT];
}
I have a question about QoS in Linux. I have the four types of packets,
let's name them A, B, C and D. I want to create four-band priority queue:
band 1: highest priority - packets of type A up to 10% of link bandwidth.
band 2: second highest priority - packets of type B up to 10% of link
bandwidth.
band 3: default priority: packets of type A and B over
the 10% of link bandwidth, packets of type C.
band 4: packets of type D. Lowest priority, no reserved bandwidth.
Can this be done using fwmark classifier and prio qdisc (maybe with
TBF attached to band 1 and 2? I have packet filter on this host anyway,
so I prefer to do it by fwmarks instead of e.g. u32.
