Dear Colleagues, I have read the "Day One: Deploying Basic QoS" book. There are a couple of questions left concering EX4200 switches.
1. In a BA classifier, traffic is assigned to a forwarding-class and a loss-priority. It is quite clear how to use forwarding-classes, but where and how do I use the loss-priority parameter? I figure it's probably used as a hook in the scheduler config somewhere, but where exactly? Moreover, it seems that when I classify traffic as "forwarding-class XXX loss-priority high", it simply gets discarded on default scheduler-maps. 2. How come I cannot set loss-priority in a port-based classifier? 3. The book says: "It is strongly advised to ensure that every forwarding-class for which any traffic may appear on an interface to which the scheduler-map is applied has a corresponding scheduler. If no scheduler is identified for a forwarding-class, and traffic arrives on that interface for that class, it will receive no explicitly configured service (for example, no buffers, no transmit-rate) and will therefore suffer very poor service unless the interface is completely unused by other traffic." Is it possible to configure a single dummy FIFO egress scheduler which would be forwarding-classes and loss-priority agnostic? There are interfaces where I only need to apply rewrite-rules on egress without prioritizing. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN sip:[email protected] _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
