I have recently discovered a change in behavior in IOS. The command show logging has traditionally been available at user level. Now it has become a privilege level 15 command.
I thought that this was strange and opened a case with Cisco TAC about it. I was told that this is a new "feature" that was implemented for bugid CSCsl61281. Unfortunately this bugid is viewable by Cisco internally but not viewable by the public.
The TAC engineer tells me that this change is integrated into these releases:
This was integrated into the following releases:
I do not think that this is a good change. If you do not think that this is a good change I suggest that you contact your Cisco support team and express your opinion about this change.
Otherwise as you go to new versions of IOS be aware of the potential impact on your network monitoring processes and procedures that show logging will require level 15 privilege access.
