2: System level
Parameters
time-value: TCP connection state check interval in seconds, in the range of 1 to 60.
Description
Use tcp timer check-state to configure the TCP connection state check interval.
Use undo tcp timer check-state to restore the default.
By default, the TCP connection state check interval is 30 seconds.
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 will accelerate the aging of TCP
connections in such a state.
Note that you need to enable the protection against Naptha attack before executing this command.
Otherwise, an error will be prompted.
Related commands: tcp anti-naptha enable.
Examples
# Set the TCP connection state check interval to 40 seconds.
