Hi, everybody!
I faced a problem of abnormal behavior of 7301 with the following configuration of QOS:
policy-map PARENT
class class-default
shape average 512000
service-policy CHILD
policy-map CHILD
class REALTIME_N
priority percent 50
class REALTIME_OV_N
priority percent 2
class PREMIUM_N
bandwidth percent 20
random-detect
class STANDART_N
bandwidth percent 2
random-detect
class MANAGEMENT_N
bandwidth percent 3
class class-default
bandwidth percent 5
random-detect
Experiment is the following:
I attach this policy as OUTPUT on Gig interface and send 3 flows (prec 5,3,1) 512 kbps each (1536 kbps total!).
I know, that the configuration is stupid, but i couldn't understand - why priority class REALTIME_N doesn't get the configured line rate (50%)! Moreover, less prioritized class PREMIUM_N get more then REALTIME_N!!!!
If I remove the unnecessary classes from CHILD policy map:
policy-map ENTERPRISE_OUT_NEW
class REALTIME_N
priority percent 50
class PREMIUM_N
bandwidth percent 20
random-detect
class class-default
bandwidth percent 5
random-detect
Everything is ok! and work properly!
If this situation is interesting for somebody - i could attach screenshot of Chariot program!
