NTP on 4500 Switch

[Bouncer]

I need assistance with the following setup please:



We have a 3Com 4500 26 port switch at work that needs to act as a "NTP server" to 5 different types of equipment(systems) all of which are on their own subnet. Connected to the switch we have a Hopf GPS clock which needs to act as the clock source. Do we need to enable the NTP server on the switch or can we simply put each of the 5 systems into their own VLAN and make the GPS clock a trunk port?

Hi,



why don't you just create a "clock" vlan and then route it through your 4500 or your router, then configure your clients to get ntp time from your gps clock ? ntp is routable, so there is no reason why you would get all the vlans to your clock.



Hope this helps.



I never configured a 3com switch as an ntp server, only client.
