Adding and Deleting SNTP Server Addresses
Adding Addresses.
As mentioned earlier, you can configure one SNTP
server address using either the Menu interface or the CLI. To configure a
second and third address, you must use the CLI. To configure the remaining
two addresses, you would do the following:
ProCurve(config)# sntp server 2001:db8::215:60ff:fe79:8980
ProCurve(config)# sntp server 10.255.5.24
Figure 9-21. Example of Creating Additional SNTP Server Addresses with the CLI
N o t e
If there are already three SNTP server addresses configured on the switch,
and you want to use the CLI to replace one of the existing addresses with a
new one, you must delete the unwanted address before you configure the new
one.
Deleting Addresses. To delete an address, you must use the CLI. If there are
multiple addresses and you delete one of them, the switch re-orders the
address priority.
Syntax:
no sntp server < ip-addr >
For example, to delete the primary address in the above example (and
automatically convert the secondary address to primary):
ProCurve(config)# no sntp server 10.28.227.141
Menu: Operation with Multiple SNTP Server Addresses
Configured
When you use the Menu interface to configure an SNTP server IP address, the
new address writes over the current primary address, if one is configured.
SNTP Messages in the Event Log
If an SNTP time change of more than three seconds occurs, the switch’s event
log records the change. SNTP time changes of less than three seconds do not
appear in the Event Log.
