Can we make Nexus7009 as NTP server

[Puneet Gupta]

Hi 

Can we make Nexus7009 as an NTP server. Basically we are craeting one MGMT vlan with HSRP configured between two chassis. HSRP IP want to use as an NTP server IP .

is it possible and if yes , what will be the configuration for NTP?

Hi,

According to the config guide:

NTP server functionality is supported starting in Cisco NX-OS Release 5.2.

But I have never been able to configure a 7k as an NTP server.

Let us know if you have any luck making a 7k an NTP server.

Hello
I have neve done this on an nexus however you can try the following:

Are you going to be pointing the 7k to an external authoritative time server and having you lan clients point to the 7K? - meaning do you still want this 7k be authoritative ntp for others even if itself ntp isnt sychronised to an external time source?
 

access-list 10 permit 192.168.10.0 0.0.0.255 ( internal lan ntp clients)
access-list 10 permit host 172.16.10.1 ( external time source)
ntp ccess-group peer accesslist 10
ntp server 172.16.10.1
tp source-interfface x.x.x.x ( managment interface)

Lan client ( 192.168.10.100)
ntp server(7k) prefer
