The ICMP protocol

The ICMP protocol allows the discovery engine to test whether a particular IP address is active and responding on the network. Depending on network latency, this protocol can be adjusted to meet the configuration on your network.

Note: You can only edit the default ICMP settings; you cannot create a new set of ICMP credentials.

To change the ICMP settings for the discovery engine:

1. From the main menu of the WhatsConnected console, select Configure > Protocol Settings/Credentials. The Protocol Settings/Credentials dialog appears.
2. Select ICMP, then click Edit. The protocol properties dialog appears.
3. Increase or decrease the Timeout settings. The default timeout is 500 milliseconds.

   Note: If you are discovering across a WAN link, increase the timeout.

4. Increase or decrease the number of ICMP Retry counts. The default number of one retry is recommended for most networks.

   Note: If you are discovering across a WAN link, increase the number of retries.

5. Click OK to save the protocol changes.
