Administering the Device
System Name and Prompt
as an NTP peer to the upstream and downstream switches, Switch B and Switch F,
respectively .
If the network is isolated from the Internet, NTP allows a device to act as if it is synchronized through NTP,
when in fact it has learned the time by using other means. Other devices then synchronize to that device
through NTP.
When multiple sources of time are available, NTP is always considered to be more authoritative. NTP time
overrides the time set by any other method.
Several manufacturers include NTP software for their host systems, and a publicly available version for
systems running UNIX and its various derivatives is also available. This software allows host systems to be
time-synchronized as well.
System Name and Prompt
You configure the system name on the Device to identify it. By default, the system name and prompt are
Switch.
If you have not configured a system prompt, the first 20 characters of the system name are used as the system
prompt. A greater-than symbol [>] is appended. The prompt is updated whenever the system name changes.
