HP Fabric Clustering System HP-UX Administrator's Guide, March 2008

Setting Time Through the CLI
Note: If you have an NTP server configured, it is recommended that you use the process described
in: “Setting the NTP Servers to Maintain the System Clock” (page 106).
To set the system clock in the CLI:
1. Login to the CLI as the super user.
2. Enter enable to enter the privileged-execute mode.
HP-IB> enable
HP-IB#
3. Enter the clock command, followed by the set keyword and the time and date in the
format hh : mm : ss dd mm yy. For example:
HP-IB# clock set 19:22:10 25 03 03
4. Save your configuration.
HP-IB# copy running-config startup-config
Setting the NTP Servers to Maintain the System Clock
Accurate time is important in network statistics. You can set the time manually or use the Network
Time Protocol to synchronize the system with the rest of your network.
It is recommended that you use Network Time Protocol (NTP) servers to set the system clock.
Synchronizing the switch system clock with NTP servers ensures accurate time and only has to
be configured once. The NTP servers synchronize the clock upon reboot and at specified intervals.
CLI Procedure
Use the following procedure to synch the system clock with an external NTP server clock.
1. Login to the CLI as the super user.
2. Enter enable to enter the privileged-execute mode.
HP-IB> enable
HP-IB#
3. Enter configure to enter the global-configuration mode.
HP-IB# configure
HP-IB(config)#
4. Enter the ntp command with the “server-one” keyword, and the IP address of the NTP
server to use as the primary server. For example:.
HP-IB(config)# ntp server-one 10.0.3.110
5. (Optional) Specify backup NTP servers using the same command syntax, except replacing
server-one with server-two and server-three.
HP-IB(config)# ntp server-two 10.0.3.111
HP-IB(config)# ntp server-three 10.0.3.112
6. Save your configuration.
HP-IB(config)# exit
HP-IB# copy running-config startup-config
Rebooting the System
The CLI is used to reinitialize the system chassis and interface cards.
