Hi Group,
I have a question about FRTS with PQ/CBWFQ,
I know that I can use 75% of the bandwith of the interface when I use
PQ/CBWFQ, By default the class-default take 25%.
But in FRTS with PQ/CBWFQ.....
What happend if before the class-default, I apply the following class
PRUEBA2 that matches ALL
policy-map PRUEBAS
class PRUEBA1
priority 600
class PRUEBA2
bandwith 168
class class-default
fair-queue
random-detect
class-map match-all PRUEBA1
match access-group 100
class-map match-all PRUEBA2
match access-group 101
access-list 100 permit ip any host 192.168.250.3
access-list 100 permit ip any host 192.168.250.4
access-list 101 permit ip any any
interface Serial0.1 point-to-point
bandwidth 1544
ip address 192.168.2.78 255.255.255.252
frame-relay class FRQoS
frame-relay interface-dlci 110
load-interval 30
map-class frame-relay FRQoS
frame-relay adaptive-shaping becn
frame-relay fecn-adapt
frame-relay cir 768000
frame-relay bc 76800
frame-relay be 76800
frame-relay mincir 768000
service-policy output PRUEBAS
I know that I can not use more than the MINCIR in the PQ and Fair queues...
So in this configuration, How much bandwith does the class-default have?
....Another question..???
In a normal configuration in the Physical interface... If I have a link of
1Mbps, So I have 75% to redistribute between the queues, What happen in the
moment of the congestion If I only use 50% in the queues??? What happen with
the 25%???
50% class 1, 2, 3
25% class-default
25%__??????
Also, If you are going to transmit VoIP over FrameRelay(PVC of voice and
data)... Cisco says that you need to configure the BE=0. So What happen if
the Service provider have the following parameters:
CIR=768000
BC=768000
BE=768000
So the FRTS is:
frame-relay cir 768000
frame-relay mincir 768000
frame-relay bc 76800
frame-relay be 0
I use a TC of 100ms, Do you think I need to use a delay of 10ms...
frame-relay cir 768000
frame-relay mincir 768000
frame-relay bc 7680
frame-relay be 0
What happen if I use the following FRTS with a TC of 100ms:
frame-relay cir 768000
frame-relay mincir 768000
frame-relay bc 76800
frame-relay be 76800
Can somebody help me please??? I really apreciated your help!!!
Rgds,
