The interval for sending a handshake packet, in unit of minute
Note: If the interval for sending a handshake packet is too long,
the NMS cannot detect the disconnection between the device and the NMS promptly.
If the interval for sending a handshake packet is too short,
the number of handshake packets that the NMS needs to handle increases,
which adds burden to the NMS.
You can set the time interval according to the actual situation.
Default: 300
Unit: Seconds
