Enable IPv6 ACL "Deny" or “Permit” logging
ACL logging enables the switch to generate
a message when IP traffic meets the criteria for a match with an ACE
that results in an explicit "deny" or “permit” action.
You can use ACL logging to help:
To help ensure that your ACL configuration is detecting and denying the incoming IPv6 traffic you do not want to enter the switch, or permitting the traffic, test your network
Receive notification when the switch denies inbound IPv6 traffic you have designed your ACLs to reject (deny), or permits traffic you have designed your ACLs to allow (permit).
