Are you seeing this on a sensor or an NTBA appliance?
Did this previously show as up?
I assume you have just edited the image above to hide the last 2 digits of the IP, is this correct?
First i notice this in RTTA there were no dashboards for NTBA
Then i typed status on Sensor and it showed me that the status is Down
Yes i marked black the last digits of IP
During the implementation it happened one or two times since then everything worked fine, i dont what happened, but recently i changed ports function from SPAN to Inline-mode and my sensor model is M 1450 so export traffic to NTBA from port 4A.
Looking forward for ur solutions, thanks
Does the NTBA show any communication faults in the manager?
Did you reconfigure the collection ports / exporters when you changed to in-line?
Do the collector ports have an IP address that sits on the same range as the NTBA mgmt interface?
If that is the case it won't work - as NTBA will try talking to NSM via collector interfaces, while NSMs is sending data to the mgmt interface
Only option is to reconfigure the IP addresses on the collector ports to a different VLAN
