How do I know if my flapping interface is enabled Linux?
If you want to see when an interface changed status to up and down, you can look at the system log file like /var/log/syslog , or dmesg output. You may get a different interface name eth0 and/or different driver name r8169 . Clearly, the first line shows when an interface goes down and other when it becomes up.
