Juniper SRX5800 Hardware Manual page 118

NOTE: When installing an SRX5K-MPC in an SRX5600 or SRX5800 Services Gateway:
If the session-distribution-mode has not been explicitly configured using the CLI command:
user@host set security forwarding-process application-services session-distribution-mode
The SRX5K-MPC defaults to hash-based mode automatically even if existing SRX5K-MPC or
non-MPCs are installed. You cannot set the session-distribution-mode to normal.
If the session-distribution-mode has been explicitly configured to normal, and the MIC is
installed in the device, then the SRX5K-MPC will remain offline, and the services gateway
generates a major alarm and logs the event for troubleshooting. You must explicitly configure
the session-distribution-mode using the CLI command:
user@host set security forwarding-process application-services session-distribution-mode
hash-based
When installing an SRX5K-MPC in an SRX5400 Services Gateway, the session-distribution-mode
will only function when hash-based mode is configured or set as the default. The normal mode
is not supported.
A 9% drop is observed for PPS (throughput) when moving from session mode to hash mode (for
SRX5K-MPC or non-MPCs), whereas no drop in performance is observed on CPS (connection
per second) and session capacity numbers.
For more information about the CLI command, see the Junos OS documentation at
www.juniper.net/documentation/.
