drop illegal-ip disable
Function
The drop illegal-ip disable command disables a device from discarding IPv4 and IPv6 packets sourced from the all-zero address.
The undo drop illegal-ip disable command enables a device to discard IPv4 and IPv6 packets sourced from the all-zero address.
By default, the function of discarding IPv4 and IPv6 packets sourced from the all-zero address is enabled.
The drop illegal-ip disable and undo drop illegal-ip disable commands are supported only by the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S. The other device models discard IPv4 and IPv6 packets sourced from the all-zero address by default, and this function cannot be disabled on those models.
