Hello I have seen most of the mails in the list ... they are using TC for shaping incoming traffic. I have a different scenario here.. Iam trying to implement a diffserv funtionalities in a cluster of linux routers. Iam having a egress router with two outgoing interfaces. my question is should i apply the same qdisc to both of the interfaces???? Question no:2 When we define the filters using the fw.. i want to know the logical connection between filters and classes. for example ************************************************* tc class add dev eth0 parent 10:110 classid 10:220 cbq bandwidth 10mbit rate 5mbit avpkt 1000. tc filter add dev eth0 parent 10:110 handle fw 1 classid 10:220. ipchains -i Output -j MARK -p tcp -m 1 ************************************************ Question is fw =1 which we are using in the filter description represent the -m 1 packets defined in the ipchains.
