The timeouts column contains key-value pairs used to
configure connection tracking timeouts in a datapath. Key-
value pairs that are not supported by a datapath are
ignored. The timeout value is in seconds.
TCP Timeouts:
timeouts : tcp_syn_sent: optional integer, in range 0 to
4,294,967,295
The timeout for the connection after the first TCP SYN
packet has been seen by conntrack.
timeouts : tcp_syn_recv: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the first TCP SYN-ACK
packet has been seen by conntrack.
timeouts : tcp_established: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the connection has
been fully established.
timeouts : tcp_fin_wait: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the first TCP FIN
packet has been seen by conntrack.
timeouts : tcp_close_wait: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the first TCP ACK
packet has been seen after it receives TCP FIN packet.
This timeout is only supported by the Linux kernel
datapath.
timeouts : tcp_last_ack: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after TCP FIN packets have
been seen by conntrack from both directions. This timeout
is only supported by the Linux kernel datapath.
timeouts : tcp_time_wait: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after conntrack has seen the
TCP ACK packet for the second TCP FIN packet.
timeouts : tcp_close: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the first TCP RST
packet has been seen by conntrack.
timeouts : tcp_syn_sent2: optional integer, in range 0 to
4,294,967,295
The timeout of the connection when only a TCP SYN packet
has been seen by conntrack from both directions
(simultaneous open). This timeout is only supported by the
Linux kernel datapath.
timeouts : tcp_retransmit: optional integer, in range 0 to
4,294,967,295
The timeout of the connection when it exceeds the maximum
number of retransmissions. This timeout is only supported
by the Linux kernel datapath.
timeouts : tcp_unack: optional integer, in range 0 to
4,294,967,295
The timeout of the connection when non-SYN packets create
an established connection in TCP loose tracking mode. This
timeout is only supported by the Linux kernel datapath.
UDP Timeouts:
timeouts : udp_first: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the first UDP packet
has been seen by conntrack. This timeout is only supported
by the userspace datapath.
timeouts : udp_single: optional integer, in range 0 to
4,294,967,295
The timeout of the connection when conntrack only seen UDP
packet from the source host, but the destination host has
never sent one back.
timeouts : udp_multiple: optional integer, in range 0 to
4,294,967,295
The timeout of the connection when UDP packets have been
seen in both directions.
ICMP Timeouts:
timeouts : icmp_first: optional integer, in range 0 to
4,294,967,295
The timeout of the connection after the first ICMP packet
has been seen by conntrack.
timeouts : icmp_reply: optional integer, in range 0 to
4,294,967,295
The timeout of the connection when ICMP packets have been
seen in both direction. This timeout is only supported by
the userspace datapath.
