Recently, we received a customer notification that a Netbotz 250 communication was lost, but in the same local network, there is an SNMP ups that is working.
Using network capture analysis, I found that Netbotz was able to receive DCE requests, but the response was sent to a different path.
Specifically,
DCE's SNMP request is sent to Netbotz via (three-layer switch) 3c:e5:a6:14:36:XX
, but the response message is sent to the 00:11:18:09:21:XX device (not the default gateway),
by MAC address, I found that the device IP is 121.1.X.188 (the default gateway is 129),
And I saw that it had a lot of routing broadcasts, and when the device was disconnected from the network, the communication with DCE was restored.
Netbotz uses a static IP, and should not change the send flow because of routing announcements? So, what causes Netbotz's data to go incorrectly? Thank you
