TMM asserts when certain ICMP packets are classified by AFM and match rules at the Global and Route Domain context with logging and log-translations enabled.
TMM crashes (assert). Traffic disrupted while tmm restarts.
This might occur in the following configurations: -- AFM Rule Logging is enabled and Log Translations is enabled in Log Profile, -- Server side AVR Statistics collection is enabled under Security :: Reporting. -- Certain ICMP packets (such as multicast ICMP echo) are classified and match AFM rules at Global and Route Domain contexts.
Disabling log-translations in AFM Logging Profile configuration can prevent the TMM crash for these types of ICMP packets.
TMM crash (assert) for certain ICMP packets when classified by AFM and logging is enabled with log-translations has been fixed.
