Solution Description and Usage
Suggestion
DoS attack Enable the anti-DoS-attack
function for OLT and
MDU.
After the anti-DoS-attack function is
enabled, control packets are
monitored and those exceeding the
number threshold are discarded.
Use this solution for new site
deployment.
IP attack Enable the anti-IP-attack
function for OLT and
MDU.
After the anti-IP-attack function is
enabled, a device discards the IP
packets received from the user side
whose destination IP address is the IP
address of the device, and therefore
the system is protected.
Use this solution for new site
deployment.
