In the above example, the dst IP in s2c flow does not match the source IP in c2s flow due to a dynamic-ip-and-port source NAT. Source and dst (destination) address with zone - Identifies the source and dst addresses for each flow of the session.c2s flow and s2c flow - Identifies flow of traffic from Client to Server (c2s) and from Server to Client (s2c).Session ID - In the example, the session ID is 524342.In the screenshot below, identify some of the important details of a session: > show session meter will display the maximum number of sessions for each VSYS on firewalls with Multiple Virtual System capabilityīelow is an example output from the > show session id command:.> show session info will display the general configuration on the firewall regarding session management and their current statistics.> show session id will show detailed information on a session based on the entered session ID.Please refer to the following document for more information: Can the Whole Session Log be Exported?
The limit is based on the byte size of the session which cannot be changed.
Note: There is a limit in the number of sessions that can be shown with the > show session all command.
Flow direction - Since each session is identified by a two uni-directional flow, each flow must be properly identified.End hosts - The source IP and destination IP which will be marked as client(source IP) and server(destination IP).On a Palo Alto Networks firewall, a session is defined by two uni-directional flows each uniquely identified by a 6-tuple key: source-address, destination-address, source-port, destination-port, protocol, and security-zone.īesides the six attributes that identify a session, each session has few more notable identifiers:
