I am not completely clear what master port means. Can anybody explain me the meaning? Also, I have MT router with 1 public interface and 2 interfaces with two clients connected to them. I want to create a quewe with pcq-s in it for traffic shaping, but I do not know which parrent to choose. I tried Global-in, but the traffic rate became very low… What can be done?
http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features
Some boards have built in switch chips that can switch in hardware at wire speed. To activate that feature you set the parent-port of ports, all ports with a parent-port are in a switch group with that port. If you want routed ports (different networks behind different ports) you want to set the parent-port to none.
Parents for queues determine what packets that queue sees. From http://wiki.mikrotik.com/wiki/Manual:Queue#Queues:
In RouterOS, these hierarchical structures can be attached at 4 different places:
global-in: represents all the input interfaces in general (INGRESS queue). Queues attached to global-in apply to traffic that is received by the router before the packet filtering
global-out: represents all the output interfaces in general (EGRESS queue).
global-total: represents all input and output interfaces together (in other words it is aggregation of global-in and global-out). Used in case when customers have single limit for both, upload and download.
: - represents one particular outgoing interface. Only traffic that is designated to go out via this interface will pass this HTB queue.
you don’t need to set any ‘master port’ because that will enable the switch mode, and if you want to manage QoS, you will probably need to do routing and NAT, no simple switch (just connects wires together, basically)
