5.2.4 Retry and timeout values
Configuring longer timeouts and more retries can result in more responses from devices that are busy or distant. This higher response rate eliminates false down messages. However, it also lengthens the time to determine that actual down devices require attention. Finding the balance for each area of your network is important and might require a period of testing and adjusting values in your environment.
To get an idea of the current lag time for each hop, execute the following commands:
In Windows: Execute tracert for a device in each network area
In Linux: Execute traceroute for a device in each network area
