Catalyst 9800-40 WLC CLI log time

t3rebello — Mon, 18 Sep 2023 16:41:04 GMT

Hi folks,

While troubleshooting an issue I noticed that the WLC 9800 CLI's log time does not match the GUI time or the time displayed when I run a show clock command.

Is there a way to sync up the log time with the configured time?

Thank you,

-Travis R.

Looks like WLC is not configured with a NTP server. Make sure you configure a NTP server and time is synch with it.

Then depend on what info you like to see in timestamp of logs, you can configure it using CLI below
service timestamps log datetime msec show-timezone year

Thank you! This command actually did the trick---your answer guided me there:

service timestamps log datetime msec localtime show-timezone

as per the output there is not NTP config - suggest to config that should fix the issue

WLC-C9800-HA#show ntp ass

address ref clock st when poll reach delay offset disp
* sys.peer, # selected, + candidate, - outlyer, x falseticker, ~ configured

Hello everything is fine?

I saw your answer and was in doubt.

What is the impact of applying this command in the production environment?

service timestamps log datetime msec show-time zone year

I think I have an NTP problem, the AP is not associating with a controller, but it has 12 APs in another store that are UPs.
