I have a customer issue with the ATM and Di1 interfaces keep flapping and when I looked at the log it says Configured from console by mypwd on vty0
I have attached the log below:
.Apr 8 16:03:20.055 AEST: %LINK-5-CHANGED: Interface Dialer1, changed state to administratively down
.Apr 8 16:03:20.079 AEST: %LINK-5-CHANGED: Interface ATM0/2/0, changed state to administratively down
.Apr 8 16:03:21.079 AEST: %LINEPROTO-5-UPDOWN: Line protocol on Interface ATM0/2/0, changed state to down
.Apr 8 16:03:27.999 AEST: %TRACKING-5-STATE: 2 interface Di1 ip routing Up->Down
.Apr 8 16:03:28.707 AEST: %SYS-5-CONFIG_I: Configured from console by mypwd on vty0 (EEM:bounce_interface_no_shut)
I have checked the upstream provider and they do not see any issues over the link. Please help

Hi Mark,
I could see some details under the NTP server:
ntp server
event manager session cli username "mypwd"
event manager applet bounce_interface_shut
event track 1 state down
action 1.0 cli command "enable"
action 1.5 cli command "config t"
action 2.0 cli command "interface dialer 1"
action 2.5 cli command "shutdown"
action 3.0 cli command "interface atm 0/2/0"
action 3.5 cli command "shutdown"
action 4.0 cli command "end"
event manager applet bounce_interface_no_shut
event track 2 state down
action 1.0 cli command "enable"
action 1.5 cli command "config t"
action 2.0 cli command "interface dialer 1"
action 2.5 cli command "no shutdown"
action 3.0 cli command "interface atm 0/2/0"
action 3.5 cli command "no shutdown"
action 4.0 cli command "end"
event manager applet Router-Reload
event track 3 state down
action 1.0 cli command "enable"
action 1.5 wait 2
action 2.0 reload

Hi Mark,
I suspect that script is tracking our third-party provider NTD device.
Here are the outcome of track 1
Track 1
Interface Dialer1 ip routing
IP routing is Up
14 changes, last change 02:00:18
Delay down 30 secs
Tracked by:
EEM applet bounce_interface_shut
I haven't implemented the mentioned commands since if the carrier NTD goes down service will drop off if the tracker is to no shut the carrier NTD. Please let me know
"
no event manager session cli username "mypwd"
no event manager applet bounce_interface_shut
no event manager applet bounce_interface_no_shut
no event manager applet Router-Reload

Thanks,
I have removed the EEM temp
no event manager session cli username "mypwd"
no event manager applet bounce_interface_shut
no event manager applet bounce_interface_no_shut
no event manager applet Router-Reload
will monitor now

Hi Mark,
Strangely, it happened again even after I have removed the following commands.
