The shared device group (level 0) is not included in this structure. If
the log values are 12, 34, 45, 0, it means that the log was generated by
a firewall (or virtual system) that belongs to device group 45,
and its ancestors are 34, and 12. To view the device group names

session. |
Maximum Encapsulation (max_encap) | Number of packets the firewall dropped because
the packet exceeded the maximum number of encapsulation levels configured
in the Tunnel Inspection policy rule (Drop packet if over maximum
tunnel inspection level). |
Unknown Protocol (unknown_proto) | Number of packets the firewall dropped because
the packet contains an unknown protocol, as enabled in the Tunnel
Inspection policy rule (Drop packet if unknown protocol inside tunnel). |
Strict Checking (strict_check) | Number of packets the firewall dropped because

Session End Reason (session_end_reason) | The reason a session terminated. If the
termination had multiple causes, this field displays only the highest
priority reason. The possible session end reason values are as follows,
in order of priority (where the first is highest): threat—The
firewall detected a threat associated with a reset, drop, or block
(IP address) action. policy-deny—The session matched a security rule with a deny
or drop action. decrypt-cert-validation—The session terminated because you
configured the firewall to block SSL forward proxy decryption or SSL inbound inspection when the session
uses client authentication or when the session uses a server certificate
with any of the following conditions: expired, untrusted issuer,
unknown status, or status verification time-out. This session end
reason also displays when the server certificate produces a fatal error alert of type
bad_certificate, unsupported_certificate, certificate_revoked, access_denied,
or no_certificate_RESERVED (SSLv3 only). decrypt-unsupport-param—The session terminated because you configured
the firewall to block SSL forward proxy decryption or SSL inbound
inspection when the session uses an unsupported protocol version,
cipher, or SSH algorithm. This session end reason is displays when
the session produces a fatal error alert of type unsupported_extension,
unexpected_message, or handshake_failure. decrypt-error—The session terminated because you configured
the firewall to block SSL forward proxy decryption or SSL inbound
inspection when firewall resources or the hardware security module (HSM) were unavailable.
This session end reason is also displayed when you configured the
firewall to block SSL traffic that has SSH errors or that produced
any fatal error alert other than those listed for the decrypt-cert-validation
and decrypt-unsupport-param end reasons. tcp-rst-from-client—The client sent a TCP reset to the server. tcp-rst-from-server—The server sent a TCP reset to the client. resources-unavailable—The session dropped because of a system resource
limitation. For example, the session could have exceeded the number
of out-of-order packets allowed per flow or the global out-of-order
packet queue. tcp-fin—One host or both hosts in the connection sent a TCP
FIN message to close the session. tcp-reuse—A session is reused and the firewall closes the
previous session. decoder—The decoder detects a new connection within the protocol (such
as HTTP-Proxy) and ends the previous connection. aged-out—The session aged out. unknown—This value applies in the following situations: Session terminations that the preceding reasons do not cover
(for example, a clear session all command). For logs generated in a PAN-OS release that does not support
the session end reason field (releases older than PAN-OS 6.1), the
value will be unknown after an upgrade to the current
PAN-OS release or after the logs are loaded onto the firewall. In Panorama, logs received from firewalls for which the PAN-OS version
does not support session end reasons will have a value of unknown.
n/a—This value applies when the traffic log type is not end.
