Enables source and destination IP address checking.
| slot | Specifies the slot. |
| all | Specifies all IP addresses, or all IP addresses in a particular state. |
The default is disabled.
This command enables source and destination IP addresses checking. This checking takes effect for both IPv4 and IPv6 packets. When enabled, the switch drops IPv4/IPv6 packets if its source IP address are the same as the destination IP address. In most cases, the condition of source IP address being the same as the destination IP address indicates a Layer 3 protocol error. (These kind of errors are found in LAND attacks.)
This command was first available in ExtremeXOS 12.0.
