Configuration Change Notification and Logging

This topic is to discuss the following lesson:


How do we send this to the syslog server? I saw a command notify syslog don’t we need an IP address?
Please clarify.


Hi Hamood,

“notify syslog” will ensure that configuration change will send messages to syslog but you will still need to configure syslog to send messages to an external syslog server. Here’s how it’s done:


Hi Rene,
Can you please give me the equivalent of these command for IOS XR?
Hope to hear from you soonest.

Hi Adekunle,

IOS XR has a similar mechanism. You can view the commit list and its changes:

RP/0/0/CPU0:ios#show configuration commit list
Mon Mar  7 11:44:19.885 UTC
SNo. Label/ID              User      Line                Client      Time Stamp
~~~~ ~~~~~~~~              ~~~~      ~~~~                ~~~~~~      ~~~~~~~~~~
1    1000000002            cisco     con0_0_CPU0         CLI         Mon Mar  7 11:44:17 2016
2    1000000001            cisco     con0_0_CPU0         CLI         Mon Mar  7 11:43:48 2016

Above you can see two changes have been made through the CLI. Here’s what the first change looks like:

RP/0/0/CPU0:ios#show configuration commit changes 1000000001
Mon Mar  7 11:44:53.743 UTC
Building configuration...
!! IOS XR Configuration 6.0.0
interface GigabitEthernet0/0/0/0
 ipv4 address

In the first change, only an IPv4 address was configured on the Gigabit interface.

Hope this helps.

I am not able to see any logged messages send to my terminal (ssh) unlike yours
%PARSER-5-CFGLOG_LOGGEDCMD: User:console logged command:enable secret *****

I still see those interface up , down messages except the LOGGED message. Does it only send to console ?


Hi Alan,

By default, syslog will only show up on the console. Not on VTY (telnet or SSH). You can enable it by typing terminal monitor on the console.
