Hi
Iam seeing these logs on the router: (Replaced IP address with x.x.x.x)
Nov 1 09:41:42: %SYS-5-CONFIG_I: Configured from tftp://x.x.x.x/R1-83137.conf by console
R1#sh run | i x.x.x.x
logging x.x.x.x
snmp-server host x.x.x.x gps21P28S19J17JH
ntp server x.x.x.x
R1#sh run

My Question:
1. The log says tftp server @ x.x.x.x configured the router & show run shows the config was indeed changed at the same time! Can someone tell me Why this is happening?
2. However the log seem to have affected only the running-config not startup-config! Why?
Thanks a lot in advance!

The running config was overwritten by someone using a config from a Tftp server. The reason the startup config hasn't been written is because it wasn't saved.

Hi Jeff,
I wonder how that could have happened? because we have TACACS+ configured on all our routers & in case anybody chages or updates configuration it should show the user id like the one below:
Nov 1 18:40:25: %SYS-5-CONFIG_I: Configured from console by
But the logs shown above doesnt show any user id which makes me think it must be some automated feature of SNMP or Syslog or NTP?

One more related log & SNMP information. hope this might help:
From Cisco Error message decoder:
%SYS-4-SNMP_HOSTCONFIGSET: SNMP hostConfigSet request. Loading configuration from [IP_address]
SNMP is reading the host configuration from a network host.
Recommended Action: This is an informational message only. No action is required.
Related documents- No specific documents apply to this error message.
From SNMP Object Navigator:

Well that would mean indeed our SNMP server uploaded configuration to our router.
But still want to know whether its a automated scheduled task & what would be the purpose one would implement it in real networks?
