Parameters
time-value: Specifies the TCP connection state check interval in seconds, in the range of 1 to 60.
Usage guidelines
The device periodically checks the number of TCP connections in each state. If it detects that the
number of TCP connections in a state exceeds the maximum number, it accelerates the aging of
TCP connections in such a state.
You must enable the protection against Naptha attack before executing this command. Otherwise,
an error is prompted.
Example
# Set the TCP connection state check interval to 40 seconds.
