GTP load balancing

You can use the following command to enable or disable GTP load balancing.

config load-balance setting

config gtp-load-balance {disable | enable}

end

By default, this option is disabled and GTP load balancing is disabled. The following flow rule is enabled and GTP traffic is directed to the primary (master) FPM.

config load-balance flow-rule
    edit 17
        set ether-type ipv4
        set protocol udp
        set dst-l4port 2123-2123
        set comment "gtp-c to master blade"
    next
end

When the gtp-load-balance option is enabled, the GTP load balancing is flow rule is disabled and GTP sessions are directed to the DP2 processors and load balanced to the FPMs.
