I am trying to find some background information regarding this error:
Cisco 6500 [SUP720-3B] %QM-4-AGG_POL_EXCEEDED QoS Hardware Resources Exceeded Out of Aggregate policers.
What triggers this error? In this case, there are QoS policies configured at the interface level. The 'show platform hardware capacity' command shows that there are1024 policers supported. What counts as a policer? Is a policer each instance of a class using the police command? I see where there have been some suggestions to use VLAN based policies instead of interface policies and others suggesting to turn off 'qos marking statistics' but I would really like to understand the details of what causes policers to be used up and how to approach fixing this.
I am trying to understand how this works under the covers but can't seem to find any documentation anywhere defining the details.
Any and all help is appreciated.
