Session Timers can be configured for TCP, UDP, and ICMP sessions.
Session Timers define how long a session is maintained on the firewall after inactivity. When the session timeout for the protocol expires, the session closes.
On the firewall, a number of timeouts for TCP, UDP, and ICMP sessions can be specified to apply to a user-defined subset of virtual machines or vNICs. By default, any virtual machines or vNICs not included in the user-defined timer are included in the global session timer. All of these timeouts are global, meaning they apply to all of the sessions of that type on the host.
Default session values can be modified depending on your network needs. Note that setting a value too low could cause frequent timeouts, and setting a value too high could delay failure detection.
