NTP access-group command

[cheery Tomato]

Gday All,

If I apply the configuration to my router

ntp access-group peer NTP_ACL

Will this mean that my router can still be quieried, from any source, for NTP and can only query the servers allowed in NTP_ACL?

If I apply the configuration to my router

ntp access-group serve NTP_ACL

Will this mean that my router can query any router for NTP updates and only restricted hosts can query my router for NTP updates?

Any feedback is greatly appreciated.

You would think that this is the way that it would work. But my experience is that if you apply one of the ntp access group functions that it will apply both types of filtering - and the function that does not have any permits will not allow that access. So my advice is that if you will apply one ntp access group that you should apply both.
