dos-control l4port
This command enables L4 Port Denial of Service protections. If the mode is enabled, Denial of
Service prevention is active for this type of attack. If packets ingress having Source TCP/UDP
Port Number equal to Destination TCP/UDP Port Number, the packets will be dropped if the
mode is enabled.
Note: Some applications mirror source and destination L4 ports - RIP for
example uses 520 for both. If you enable dos-control l4port,
applications such as RIP may experience packet loss which would
render the application inoperable.
no dos-control l4port
This command disables L4 Port Denial of Service protections.
dos-control smacdmac

enabled.
