Hi,group
May I expect anyone help for qos? thank you very much.
Question one:rsvp over frame relay multipoint interface
assume interface access rate is 1544kbps#,have two VC#(dlci 100#,200#)connect two spoke router,assume bandwidth reserved is 80K for per VC,follow is my config,but I cann't confirm 'ip rsvp band 80 80' or 'ip rsvp 160 160'.
another question is 'rserve bandwidth' must less than 'frame mincir <bps>'?
HUB router:
...
int s0
encap frame
frame traffic-shaping
ip rsvp band 80 80
int s0.1 multipoint
ip add ....
frame map ip .... 100 bro
frame map ip .... 200 bro
ip rsvp band 80 80
frame interface-dlci 100
class fast
frame interface-dlci 200
class slow
map-class frame fast
frame cir 256000
frame mincir 128000
frame bc 2560
frame fair-queue
frame fragment 280
no frame adaptive-shaping
map-class frame slow
frame cir 128000
frame mincir 640000
frame bc 1280
frame fair-queue
frame fragment 280
no frame adaptive-shaping
...
SPOKE router (vc100):
int s0
encap frame
ip add ...
frame taffic-shaping
ip rsvp band 80 80
frame interface-dlci 100
class fast
map-class frame fast
frame cir 256000
frame mincir 128000
frame bc 2560
frame fair-queue
frame fragment 280
no frame adaptive-shaping
Question two:cbwfq over frame relay(this is a config in cco document-cd)
class-map voice
match access-group 101
class-map immediate-data
match access-group 102
class-map priority-data
match access-group 103
access-list 101 permit udp any any range 16384 20000
access-list 102 permit ip any any precedence immediate
access-list 103 permit ip any any precedence priority
policy-map mypolicy
class voice
priority 16
class immediate-data
bandwidth 32
random-detect
class priority-data
bandwidth 16
class class-default
fair-queue 64
queue-limit 20
interface Serial1/0.1 point-to-point
frame-relay interface-dlci 100
class fragment
map-class frame-relay fragment
frame-relay cir 64000
frame-relay mincir 64000
frame-relay bc 640
frame-relay fragment 80
service-policy output mypolicy
my question is how many bandwidth is allocated traffic for class-default in above config ?
if use 'bandwith' in class-default,follow config is right ? class-default BW=total BW - allocated BW?
policy-map mypolicy
class voice
priority 16
class immediate-data
bandwidth 16
random-detect
class priority-data
bandwidth 16
class class-default
bandwidth 16
queue-limit 20
best regards !
