Command Syntax and Usage | |
---|---|
ipttl <IPv4 TTL, 0-255> | |
Sets the smallest allowable IP TTL for IPTTL. | |
ipprot <highest allowable IPv4 protocol [0-255]> | |
Set the highest allowable IP protocol for IP protection. For example: Current highest allowable IPv4 protocol: 137 Enter new highest allowable IPv4 protocol [0-255]: | |
fragdata <IPv4 fragment payload size in bytes, 16-248> | |
Sets the smallest allowable IP fragment payload. | |
fragoff <IPv4 fragment offset in multiples of 8 bytes, 1-255> | |
Sets the smallest allowable IP fragment offset. | |
syndata <TCP packet payload size in bytes, 0-255> | |
Sets the largest allowable IP SYN payload. | |
icmpdata <ICMP packet payload size in bytes, 1-9026> | |
Sets the largest allowable ICMP payload. | |
icmpoff <ICMP fragment offset in multiples of 8 bytes, 1-8190> | |
Sets the largest allowable ICMP fragment offset. | |

Description of the anomaly and DoS attacks that are being prevented. | |
cur | |
Displays the current protocol anomaly and DoS attack prevention settings. For example: Current protocol anomaly and DoS attack prevention settings: ipttl 1, ipprot 137, fragdata 32, fragoff 4, syndata 0, icmpdata 800, icmpoff 101 |
