ACE default policy for class-default?

[gwhuang5398]

In a Layer3/4 policy-map, class-default is implicitly configured for traffic that does not match any of the class-maps. What's the default behavior or policy for class-default? Is traffic in this calss being routed/switched without load balancing by ACE using its own routing table or ARP table? or being dropped?

Thanks a lot

The class-default class is not implicitly configured. It's a predefined class that implicity matches anything not matched by the other classes in the policy.

There is no default action. You need configure the action(s) you wish to be applied to this traffic. See:

When doing Layer 3/4 load balancing, your load balance policy would only have the class-default class defined under it.
