Configuration Guide Configuring FPM
tcp-syn-receive: Sets the aging time of TCP flows in tcp-syn-receive status, which is 10 seconds by
default and ranges from 5 to 30.
tcp-time-wait: Sets the aging time of TCP flows in tcp-time-wait status, which is 10 seconds by
default and ranges from 5 to 60.
udp-closed: Sets the aging time of UDP flows in closed status, which is 10 seconds by default and
ranges from 5 to 60.
udp-connected: Sets the aging time of UDP flows in connected status, which is 30 seconds by
default and ranges from 10 to 300.
udp-established: Sets the aging time of UDP flows in established status, which is 600 seconds by
default and ranges from 120 to 600.
udp-started: Sets the aging time of UDP flows in started status, which is 10 seconds by default and
ranges from 10 to 300.
num: Sets the aging time
Global configuration mode
Use the no form of the commands to restore the default aging time.
2.4.2.4 Verification
Use the show run command to check whether the configuration includes ip session timeout. If no, the default aging
time applies.
2.4.2.5 Configuration Example
If there are a large number of UDP-established flows which occupy a great space of the flow table on
the current forwarding device, you can shorten the aging time of the UDP-established flows to
improve aging efficiency.
Set the aging time of flows in udp-established status to 120 seconds.
Ruijie# configure terminal
Ruijie(config)# ip session timeout udp-established 120
Check the aging time of flows in udp-established status on the device. The aging time should be 120
seconds.
Use the show run command to verify that the configuration contains the following item:
ip session timeout udp-established 120
This indicates that the aging time is 120 seconds.
