Certain ICMP packets (such as ICMPv6 Destination Unreachable) match twice against Global and Route-Domain ACL rules.
Global and Route-Domain ACL rules are evaluated twice under conditions specified above. This causes the rule counters to be incremented by 2 (instead of 1) and may cause double logging if enabled.
AFM provisioned and licensed. Create a Global and/or Route Domain ACL policy with a rule matching ICMP traffic. Send ICMP packet such as Destination Unreachable.
None
ICMP traffic is now evaluated only once against Global and Route-Domain ACL rules.
