Adjusting global DP2 timers

This section describes the global DP2 timers that you can adjust from the CLI. These timers affect the operation of the FortiGate-7000E DP2 processor.

config global

config system global

set dp-fragment-timer <timer>

set dp-pinhole-timer <timer>

set dp-tcp-normal-timer <timer>

set dp-udp-idle-timer <timer>

end

dp-fragment-timer the time to wait for the next fragment of a fragmented packet. The range is 1 to 65535 seconds. The default is 120 seconds. See Load balancing TCP, UDP, and ICMP sessions with fragmented packets.

dp-pinhole-timer the time to wait to close a pinhole if no more matching traffic that would use the pinhole is received by the DP2 processor. The range is 30 to 120 seconds. The default is 120 seconds.

dp-tcp-normal-timer the time to wait before the DP2 processor closes an idle TCP session. The range is 1 to 65535 seconds. The default is 3605 seconds. Some FortiGate-7000E implementations may need to increase this timer if TCP or UDP sessions with NAT enabled are expected to or found to be idle for more than 3605 seconds.

dp-udp-idle-timer the time to wait before the DP2 processor closes an idle UDP session. The range is 1 to 86400 seconds. The default is 0, which means the DP2 processor uses the UDP idle timer set by the udp-idle-timer option of the config system global command.
