Hi

I'm simulating a network topology with tcsim.

I defined some multiple interfaces on different hosts with each their own tc-configuration. In two configurations I am using meters for each two classes.

Now the problem is, that one meter in the first configuration also shapes the second configuration although a different meter is configured there. I suppose, that the simulator uses for both configurations the same meter. how can I fix this problem?

In the code below it meens: The second meter in vmu1 has to drop all video (tos=2) packets from the vmu1 (vmu1.tcc line2). In vmu2 the meter for video packet is set to 4000kbps (vmu1.tcc line2), but it is still the configuration from vmu1 set. If I set the video meter in vmu1 to 1000kbps, the policing in vmu2 is also set to 1000kbps.

Here are the neccassary scripts:

Configuration of the whole simulation (simulation.sim)://CONFIGURATION host { dev vmu1_eth0 10Mbps { #include "vmu1.tcc" } route default vmu1_eth0 } host { dev vmu2_eth0 10Mbps { #include "vmu2.tcc" } route default vmu2_eth0 } //ixbBlade1 host { dev ixbBlade1_eth0 10Mbps dev ixbBlade1_eth1 10Mbps dev ixbBlade1_eth2 10Mbps route default ixbBlade1_eth2 } connect vmu1_eth0 ixbBlade1_eth0 connect vmu2_eth0 ixbBlade1_eth1 /*===========================================================================================================*/ //TRAFFIC GENERATION //from vmu1 every 0.000521s send vmu1_eth0 UDP_PCK( $ip_tos = 1 $ip_src = 10.1.1.1 ) 0 x 172 //3000kbps voice //from vmu2 every 0.000625s send vmu2_eth0 UDP_PCK( $ip_tos = 2 $ip_src = 10.1.1.2 ) 0 x 372 //5000kbps video //from ixbBlade1 every 0.000521s send ixbBlade1_eth2 UDP_PCK( $ip_tos = 1 $ip_src = 10.1.0.10 ) 0 x 172 //3000kbps voice time 10s end
