Thank you Steve for the quick answer.
Problem is being traced back to a single switch port on which a faulty device may have been connected. More on this later today.
Hopefully, I'll be able to find exactly how this was created to duplicate it in lab.
I'll keep the post update and send later as basic schematic of the setup.
In the meantime, I have a follow-up question.
Mon Aug 23 19:00:42 2021 vlan_name QinQ-MRCRN-3913 mac 00:00:0a:9b:37:13 was moved from ge-0/0/11.3913 to ge-0/0/0.3913 with flags: 0x2101f
Issuing the command " show Ethernet-table mac-learning-log | match move" is becoming my way to see if a I have a switch flapping. But I have 3 problems
1) I have to issue the command.
a. I would appreciate a sflow or snmp trap or whatever warning me that a port moving just occurred.
b. Iby the way, I am using Junos Space and Network Director, though I am not a power user.
2) I can't seem to find log on the switch of these "move." I looked at the log message files to no avail.
a. There must be a trace womewhere of what happened ?
3) The time displayed does not seems to match the actual time the event occurred.
a. Still have to check on other switches, but this seems real odd.
b.
I'd like to read your thoughts on these issues. I also may open a ticket with Junniper for further inquiries.
thanks
