I am answering my own question here in hopes that anyone reading the 
archive might benefit.

Working syntax is below:

dev eth0 {
htb (rate 128kbps, ceil 150kbps ) {
$c1 = class {
htb (rate 100kbps, ceil 120kbps ) {
class if 1 {
sfq(perturb 10secs);
}
}
};
$c2 = class {
htb (rate 50kbps, ceil 60kbps ) {
class if 1 {
sfq(perturb 10secs);
}
}
};
fw {
class $c1 on (1);
class $c2 on (2);
}
}
}

[LARTC] TCNG fw classifier question

2003-03-04 Thread bauer 
I think I must have the syntax wrong for using the firewall classifier
in TCNG.  Can anyone offer any suggestions for what I am doing wrong.  
Details below...

#include packet.def

dev eth0 10 {
htb (rate 128kbps, ceil 150kbps ) {
fw;
class (0x100) {
htb (rate 100kbps, ceil 120kbps ) {
class if 1 {
sfq(perturb 10secs);
}
}
}
class (0x200) {
htb (rate 50kbps, ceil 60kbps ) {
class if 1 {
sfq(perturb 10secs);
}
}
}
}
}

send nfmark=0x100 TCP_PCK()
send nfmark=0x200 TCP_PCK()
end

Invoked with tcsim -v -v -v test3.tcsim.  You can 
see in the resulting simulation run that the packet never 
makes it to the queues I had intended, namely the sfqs.
