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.

To change the ICMP settings for the discovery engine:

1. From the main menu of the WhatsConnected console, select Configure > Protocol Settings. The Protocol Settings dialog appears.
2. The left pane of the dialog displays all registered protocols; ICMP is a default protocol. Select the root ICMP node to expand the tree node.
3. Select ICMP 1. The protocol settings appear in the right pane.

   Important: You must have at least one ICMP protocol setting for discovery to operate properly.

4. Increase or decrease the Timeout settings. The default timeout is 500 milliseconds.

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

5. Increase or decrease the number of ICMP Retries. 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.

6. Click OK to save the protocol changes.
