signature detect
Use signature detect to configure signature detection for single-packet attacks.
Use undo signature detect to remove the signature detection configuration for single-packet attacks.
Syntax
signature detect { fraggle | fragment | impossible | ip-option-abnormal | land | large-icmp |
