Overview

This document describes how to set and view session, TCP and UDP timeout settings from the PAN-OS web UI and CLI.

Details

To configure Session Timeouts:

  • From the web UI, go to Device >Setup > Sessions > Session Timeouts.
    PAN-OS 5.0, 6.0

From the CLI, the timeout value can be changed with the following command which is not persistent with restart of the device:

    > set session timeout-udp <1-15999999>

    > set session timeout-tcp <1-15999999>


From the CLI, use the following commands in configure mode to make changes persistent with a device reboot:

For default session timeout setting

# set deviceconfig setting session timeout-default

  <value>  <1-15999999> set session default timeout value in seconds

For session timeout-tcp setting

# set deviceconfig setting session timeout-udp

  <value>  <1-15999999> set udp timeout value in seconds

For session timeout-udp setting

# set deviceconfig setting session timeout-tcp

<value>  <1-15999999> set tcp timeout value in seconds

        Perform a commit to save changes made to the configuration

# commit

After the commit operation is performed, the modified timeouts can be viewed through session information:

> show session info | match timeout

Session timeout

       TCP default timeout:                           3600 secs

       TCP session timeout before SYN-ACK received:      5 secs

       TCP session timeout before 3-way handshaking:    10 secs

       TCP session timeout after FIN/RST:               30 secs

       UDP default timeout:                             30 secs

       ICMP default timeout:                             6 secs

       other IP default timeout:                        30 secs

       Captive Portal session timeout:                  30 secs

       Session timeout in discard state:

         TCP: 90 secs, UDP: 60 secs, other IP protocols: 60 secs
