I'll take a crack at this.
Does CBWFQ work in frame-relay sub interface.
Only in upper releases of 12.2 IOS
When i should use queuing in the physical interface or sub interface
Q'ing is on main interface only, sub-if's won't take a queuing type
of config command. Traffic shaping map applied to the main interface
will apply the same map to all sub-interfaces. You can apply different
ones to different sub-interfaces if needed.
and when in the frame-relay class.
When you want to put a "service-policy' on a sub-int and it is not
12.2.x IOS
when i should use ip rsvp bandwidth and when frame-relay voice bandwidth.
frame-relay voice bandwidth is for VOfr. IP RTP priority is for VOip.
RSVP is
configured on all routers and is not really a queue/buffer prioritizes
like cbwfq or
ip rtp priority queuing
when i should use frame-relay ip rtp priority and when priority in cbwfq.
These are close to the same, cbwfq will prioritize odd and even port
numbers where
rtp priority only does even port numbers. CBWFQ is also more granular
since you can
prioritize any traffic and not just RTP traffic (which is UDP only)
whether i should put exact bandwidth or little more in priority (cbwfq),
example in place of 50 , i want to put 52. is this ok.
This is more a design question...answer would be "depends"
In custom queue i should use 0 as first queue or 1.
I don't know, try it.
when we are configuring queuing in frame-relay, do we need to configure
frame-relay traffic-shaping also or not.
No, queuing and traffic shaping are 2 different things.
