Configuration Guide Configuring FPM
2.4.1.3 Configuration Steps
Optional configuration.
By default, packets can be transparently transmitted without flow establishment when the flow table is full. You can use
the ip session direct-trans-disable command to disable the function.
ip session direct-trans-disable
Packets can be transparently transmitted without flow establishment when the flow table is full.
Global configuration mode
Use the no form of this command to enable the transparent transmission function.
2.4.1.4 Verification
Use the show run command to check whether the configuration includes ip session direct-trans-disable. If no, the
transparent transmission function is enabled.
2.4.1.5 Configuration Example
If the NAT service is required on the current wireless device, you need to disable the transparent
transmission function because the NAT service does not allow the transparent transmission of IP
packets without flow establishment.
Disable transparent transmission of packets without flow establishment when the flow table is full.
Ruijie# configure terminal
Ruijie(config)# ip session direct-trans-disable
Use the show run command to verify that the configuration includes ip session direct-trans-disable.
2.4.1.6 Common Errors

2.4.2 Configuring the Flow Entry Aging Time
2.4.2.1 Networking Requirements
Reasonably make use of system flow table resources so as to reduce "useless" flow entries in the flow table and meet
the requirement for exchanging service data flows.
2.4.2.2 Notes
There is a default aging time upon system initialization, which can meet practical requirements in most scenarios.
Therefore, the configuration is optional.
Because a certain time is required before the system detects the corresponding flow, the actual aging time is slightly
later than the configured aging time.
