Opened: Mar 30, 2015
Severity: 3-Major

Symptoms

Certain ICMP packets (such as ICMPv6 Destination Unreachable) match twice against Global and Route-Domain ACL rules.

Impact

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.

Conditions

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.

Workaround

None

Fix Information

ICMP traffic is now evaluated only once against Global and Route-Domain ACL rules.
