Hi,
I have N7k with NX-OS 6.2 (16), and divided with one admin vdc and a Prod vdc.
I have 3 external NTP server (10.92.5.58, 10.92.5.59 and 10.7.11.6).
The vdc admin is configured like this (3 ntp server; source interface: management) :
interface mgmt0
description Mgmt0-N7K-1
vrf member management
ip address 10.197.99.100/24
N7K-Admin# show ntp peers
--------------------------------------------------
Peer IP Address Serv/Peer
--------------------------------------------------
10.92.5.58 Server (configured)
10.92.5.59 Server (configured)
10.7.11.6 Server (configured)
N7K-Admin# show ntp peer-status
Total peers : 3
* - selected for sync, + - peer mode(active),
- - peer mode(passive), = - polled in client mode
remote local st poll reach delay vrf
-------------------------------------------------------------------------------
*10.92.5.58 10.197.99.100 3 64 377 0.01596 management
=10.92.5.59 10.197.99.100 3 64 377 0.01591 management
=10.7.11.6 10.197.99.100 3 64 377 0.00061 management
In this configuration, the 3 ntp servers, replace an old ntp server (10.92.1.4). So, I want that only the IP of management interface of the Admin vdc (10.197.99.100) sends ntp requests to ntp servers (10.92.5.58, 10.92.5.59 and 10.7.11.6).
The problem is that the old ntp server (10.92.1.4) receive again the ntp requests from the Loopback interface0 (10.103.17.253) of the vdc Prod.
Loopback0 interface configuration of the vdc Prod :
interface loopback0
ip address 10.103.17.253/32
ip router ospf LAN area 0.0.0.0
Show command on the vdc Prod:
N7k-Prod# show ntp peers
INFO: System clock is not controlled by NTP in this VDC
You can use "clock protocol <protocol> vdc <vdc_id>"
to change the current setting.
N7k-Prod# show ntp peer-status
INFO: System clock is not controlled by NTP in this VDC
You can use "clock protocol <protocol> vdc <vdc_id>"
to change the current setting.
N7k-Prod# show ntp source
No Source IP address configured.
N7k-Prod# show ntp status
Distribution : Disabled
Last operational state: No session
Thank you.
