Disable NTP Queries

[raghavgururajan]

I wanted to disable NTP Control Messages (Mode 6).

Based on this post, I did `no ntp allow mode control`. Then, when I do `show running-config | include ntp`, I see `no ntp allow mode control 3` instead of `no ntp allow mode control 0`.

So, did I disable NTP Queries or enable it without 3s delay?

Cisco IOS Software [Bengaluru], Catalyst L3 Switch Software (CAT9K_LITE_IOSXE), Version 17.6.4, RELEASE SOFTWARE (fc1)

While the upgrade/replacement is planned, I'd like to know whether `no ntp allow mode control` disabled the NTP Queries or enabled it without 3s delay.

I'm asking this because - as per referenced post - running `no ntp allow mode control` command will make `no ntp allow mode control 0` appear in running-config. In my case, `no ntp allow mode control 3` appears in running-config.
