Procedure
1 Access the appliance shell and log in as a user who has the administrator or super administrator role.
The default user with super administrator role is root.
2 To reset specic arguments, run the command snmp.set --arguments reset.
For example, to reset the communities that you congured, run the following command:
snmp.set --communities reset
3 To reset the whole SNMP conguration to the factory defaults, run the command snmp.reset.
Configuring Time Synchronization Settings in the
vCenter Server Appliance
You can change the time synchronization seings in the vCenter Server Appliance after deployment.
When you deploy the vCenter Server Appliance, you can choose the time synchronization method to be
either by using an NTP server or by using VMware Tools. In case the time seings in your vSphere network
change, you can edit the vCenter Server Appliance and congure the time synchronization seings by using
the commands in the appliance shell.
When you enable periodic time synchronization, VMware Tools sets the time of the guest operating system
to be the same as the time of the host.
After time synchronization occurs, VMware Tools checks once every minute to determine whether the
clocks on the guest operating system and the host still match. If not, the clock on the guest operating system
is synchronized to match the clock on the host.
Native time synchronization software, such as Network Time Protocol (NTP), is typically more accurate
than VMware Tools periodic time synchronization and is therefore preferred. You can use only one form of
periodic time synchronization in the vCenter Server Appliance. If you decide to use native time
synchronization software, vCenter Server Appliance VMware Tools periodic time synchronization is
disabled, and the reverse.
Use VMware Tools Time Synchronization
You can set up the vCenter Server Appliance to use VMware Tools time synchronization.
Procedure
1 Access the appliance shell and log in as a user who has the administrator or super administrator role.
The default user with super administrator role is root.
2 Run the command to enable VMware Tools time synchronization.
timesync.set --mode host
3 (Optional) Run the command to verify that you successfully applied the VMware Tools time
synchronization.
timesync.get
The command returns that the time synchronization is in host mode.
The time of the appliance is synchronized with the time of the ESXi host.
