There are cases where it appears that there's a high latency or packet loss from the Orion server. This can often times result in the thought that Orion itself is causing these issues, or that the software is misrepresenting the correct information. This article describes how to check if it is actually an issue with ARP.
All versions of NPM
3. Check the subnet mask of the host 10.10.192.100 and destination host 10.10.192.168.
To verify the cause of the problem:
When the ARP cache entry for 10.10.192.168 is present in the ARP table, the ping should have no issues.
2. Delete the ARP entries for 10.10.192.168.
The ping should show large delays and packet loss. The behavior is the same when Orion is running or not. After a while, the ARP entry will show in the table again, and the ping will work fine again. This verifies that the ICMP issue is caused by the ARP cache management at the host.
