Two sites A & B have qos configuration specially for voice.Configurations have been attached.Both are attached as outbound on wan interfaces.
1)the markings of ef,cs5 & cs3,af31- are they different from each other.Like is ef different from Cs5?
2)does the existing configuration mean that any other traffic apart from these two would be treated in default queue on the available bandwidth?
3)I understand that dscp values are markings for the packets to be treated on each hop accordingly.That means even if a normal class of traffic is put to ef5, it will be given preference?
4)how does the device know that ef5 belongs to voice ? cant it be anything else?
5) i need to include another sensitive class of traffic in here.Would it be better to include dscp markings to tag and treat it or would acl's on both sides for that traffic be better?
if dscp , pls suggest a sample configuration.
What does fair queue server as.
You can use a bandwidth statement, like other non-LLQ classes. This defines a single queue for all class-default traffic.
Personally, I like FQ very much, and again, the issue I see might not arise at all for your traffic. However, if you really, really need to insure some applications get a bandwidth guarantee, it's something to be aware of.
