Hi,
I attempt to understand configuration below:
TRAFFIC CLASSICIATION (I have only af31 and 1F11 in reality:
************************************************************************
class-map DSCP-OUT-D1INP
match not access-group DSCP-OUT-PROBE
match ip dscp af31
exit
class-map DSCP-OUT-D2INP
match not access-group DSCP-OUT-PROBE
match ip dscp af21
exit
class-map DSCP-OUT-D3INP
match not access-group DSCP-OUT-PROBE
match ip dscp af11
exit
POLICIES APPLIED TO MY CLASSIFIED TRAFFIC:
***********************************************************
policy-map COS-OUT-D1
class DSCP-OUT-D1INP
police cir 552 6900 => Normally police cir is indicated in bps but in my case it seems to be indicated in kbps ???
police exceed-action set-dscp-transmit 28
exit
exit
policy-map COS-OUT-D2
class DSCP-OUT-D2INP
police cir 276 4500
police exceed-action set-dscp-transmit 20
exit
exit
policy-map COS-OUT-D3
class DSCP-OUT-D3INP
police cir 92 4500
police exceed-action set-dscp-transmit 12
exit
exit
GLOBAL POLICY APPLIED ON OUTPUT TRAFFIC:
************************************************************
policy-map COS-OUT
class DSCP-OUT-D1
bandwidth percent 60 =>Does this parameter applie on normal traffic or during a congestion ? (For me, is during a congestion)
service-policy COS-OUT-D1 => Why using police cir and bandwidth in a same time ?
exit
class DSCP-OUT-D2
bandwidth percent 30
service-policy COS-OUT-D2
exit
class DSCP-OUT-D3
bandwidth percent 10
service-policy COS-OUT-D3
exit
exit
interface atm 0.1

service-policy output COS-OUT
exit
**********************************************
police cir 552 6900 => Normally police cir is indicated in bps but in my case it seems to be indicated in kbps ???
bandwidth percent 60 =>Does this parameter applie on normal traffic or during a congestion ? (For me, is during a congestion)
service-policy COS-OUT-D1 => Why using police cir and bandwidth in a same time ?
Which of both parameters (bandwidth percent and service-policy) will be applied in priority ?
I'am not an expert on Cisco QoS but I must be understanding this configuration for my client. Could you please help to understand correctly QoS configuration above ?
Thanks in advance, regards,
Franck
