Managing the device
Device management includes monitoring the operating status of devices and configuring their running
parameters.
Storage media include Flash, compact Flash (CF), and universal serial bus (USB). Flash is exemplified in
this document.
The configuration tasks in this document are all optional and independent from one another.
Configuring the device name
A device name identifies a device in a network and works as the user view prompt at the CLI. For
example, if the device name is Sysname, the user view prompt is .
To configure the device name:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the device name. sysname sysname
Optional.
By default, the device name is
H3C.
Changing the system time
You must synchronize your device with a trusted time source by using NTP or changing the system time
before you run it on the network. Network management depends on an accurate system time setting,
because the timestamps of system messages and logs use the system time.
In a small-sized network, you can manually set the system time of each device.
Configuration guidelines
You can change the system time by configuring the relative time, time zone, and daylight saving time. The
configuration result depends on their configuration order (see Table 17 ). In the first column of this table,
1 represents the clock datetime command, 2 represents the clock timezone command, and 3 represents
the clock summer-time command. To verify the system time setting, use the display clock command. This
table assumes that the original system time is 2005/1/1 1:00:00.
