LARTC - Feb 2003 - [tcng] specifing interface in IF ?!

does anyone know how can I make class-path based on interface from which the
packet comes ?!


dev eth0 {
	class(<$c1>) if interface-eth0;

	egress {
		htb() {
			$c1 = class(rate 1mbps) {
				class(rate 100kbps, ceil 150kbps) if ip_dst == x.x.x.x;
				class(rate 50kbps, ceil 100kbps) if ip_dst == y.y.y.y;
			}
		}
	}
}


any idea ?!

We implemented something like this:
dev "s0e0" {
    ingress {
        class (<>,set_color(GREEN))
            if tcp_dport == PORT_HTTP;
        class (<>,set_color(YELLOW))
            if tcp_dport == PORT_SMTP;
        class (<>,set_color(RED))
            if 1;
    }
}

dev "s1e0" {
    egress {
        class (<>,set_dscp(0x12))
            if color == GREEN;
        class (<>,set_dscp(0x23))
            if color == YELLOW;
        class (<>,set_dscp(0x34))
            if color == RED;
        drop if 1; /* not reached */

        fifo;
    }
}

but you can''t do this with tcng-tc.

I was reading the some of the post and idea comes to my mind...
If I mark the packets incoming from some interface with iptables and then use
this mark for classifing in tcng..
(I see there is "fw"-classifier in tcng language, dont know how to use
it...).
Did u tried something like this..
