Hi - I'm using a parent policy-map to shape traffic for a child policy-map that assigns different traffic classes bandwidth percentages.


All the examples I've seen use class-default in the parent policy-map, but my concern is that if I do this then ALL traffic including management, routing updates etc. will be shaped, when it is only 4 specific traffic types I want to be shaped.


If I specify another class, that matches the same 4 classes as the child policy-map as opposed to using class-default as shown as possible alternative solution at the bottom, would that shape only the internet services and queue everything else as normal without including it in the shaping?


class-map match-all RAVPN

match access-group name RAVPN

class-map match-all ECOMM

match access-group name ECOMM

class-map match-all SSVPN

match access-group name SSVPN

class-map match-all PROXY

match access-group name PROXY

!

policy-map TRAFFIC_BW%

class RAVPN

bandwidth percent 20

class ECOMM

bandwidth percent 50

class SSVPN

bandwidth percent 25

class PROXY

bandwidth percent 5


policy-map SHAPER

class class-default

shape average 16000000

service-policy TRAFFIC_BW%


=========================================

possible alternative solution?


class-map match-any TRAFFIC_GROUP

match access-group name PROXY

match access-group name ECOMM

match access-group name RAVPN

match access-group name SSVPN


policy-map SHAPER

class TRAFFIC_GROUP

shape average 16000000

service-policy TRAFFIC_BW%

class class-default
