Two of our CTS3000 systems have started to give weird warning message into log files. This message appears time to time, ~6-8 time in a day.
WARN Display loopback state removal attempt
We are running sw version CTS 1.6.6(4109), but it happened also with version 1.6.5(4097) as well.
I've tried to find explanation from CTS syslog messages documentation, but no success.
Is this something to be worried about?
Solved! Go to Solution.
I wouldnt worried, any pattern, do you see it before a call started?
Do you see it when loopback is started, then stopped?
Any drop calls reported?
Can you upload sysop logs to double check
I downgraded both units to 1.6.4(4072) and this message does not appear anymore.
Question is: What is meaning of this error message as it has been added to 1.6.5 version (and later)???
That cdets is not visible to Cisco outsiders, but I heard from local Cisco SE that it should be fixed in 1.6(4). Fine, still root cause for this message is unknown to me and explanation what this message means. As it is WARNING type of message, I'd like to know what causes this warning. Can you elaborate meaning and cause of this message.
Some detailed informaton on this issue for those who do not have it.
