Configuration Examples for Configuring Flow Aware QoS
Configuring Flow Aware CAC Reject Action: Example
In this example, two class-maps are created and their match criteria are defined for access-list 102 and match
class "video". This flow rate is configured in the admit cac local configuration sub-mode. If any new flow is
learnt apart from the already admitted flows, then the new flow is rejected and packets of the flow are dropped.
All other packets are classified under class-default and are policed at 30 mbps.
class-map match-all prec5

class-map match-any video

policy-map premium-services

end
Configuring Flow Aware CAC Redirect Action: Example
In this example, three class-maps are created and their match criteria are defined for match class "dscp_cs5",
match class cac, match class "dscp_cs6". This flow rate is configured in the admit cac local configuration
sub-mode. If any new flow is learnt apart from the already admitted flows, then the new flow is redirected
and the packets for that flow are handled by the redirect class "class-default" in policy "video_flows". All
other packets are classified under class-default and are policed at 30 mbps.
