Symptoms

When TMM finds a matching ACL entry while enforcing the ACL, and that ACL entry is configured to produce a log entry as well, and the IP protocol for that packet is 255, then TMM crashes.

Impact

Traffic disrupted while tmm restarts.

Conditions

1. Log is enabled for that ACL entry. 2. IP protocol is set to 255

Workaround

Disable ACL logging

Fix Information

TMM no longer crashes when logging a matching ACL entry for IP datagram with protocol set to 255.
