Maximizing ALG Sessions

On SRX3400, SRX3600, SRX5600, and SRX5800 devices, by default, the session capacity number for RTSP, FTP, and TFTP ALG sessions is 10,000 per flow SPU. The maximize-alg-sessions option enables you to increase defaults as follows:

• RTSP, FTP, and TFTP ALG session capacity: 25,000 sessions per flow SPU
• TCP Proxy connection capacity: 40,000 sessions per flow SPU

Note: Flow session capacity will be reduced to half per flow SPU and the above capacity numbers will not change on the central point SPU.

You can configure maximum ALG sessions as follows:

You must reboot the device (and its peer in the chassis cluster) for the configuration to take effect.
