You can change the device hostname displayed in the command prompt from the default (switch) to another character string. When you give the device a unique hostname, you can easily identify the device from the command-line interface (CLI) prompt.
The message-of-the-day (MOTD) banner displays before the user login prompt on the device. This message can contain any information that you want to display for users of the device.
If you do not synchronize your device with a valid outside timing
mechanism, such as an NTP clock source, you can manually set the clock time
when your device boots.
For information about NTP, see the
Cisco Nexus 7000 Series NX-OS System Management Configuration Guide, Release 5.x.
The Cisco Nexus chassis may contain clocks of different types that may need to be synchronized. These clocks are a part of various components (such as the supervisor, LC processors, or linecards) and each may be using a different protocol.
The clock manager provides a way to synchronize these different clocks.
Time Zone and Summer Time (Daylight Saving Time)
You can configure the time zone and summer time (daylight saving time) setting for your device. These values offset the clock time from Coordinated Universal Time (UTC). UTC is International Atomic Time (TAI) with leap seconds added periodically to compensate for the Earth's slowing rotation. UTC was formerly called Greenwich Mean Time (GMT).
You can display the active user session on your device. You can also
send messages to the user sessions. For more information about managing user
sessions and accounts, see the
Cisco Nexus Security Configuration guide for your device.
Virtualization Support for Basic Device Management
Basic device management is local to the virtual device context (VDC). For more information on VDCs, see the
Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide.
Licensing Requirements for Basic Device Management
The following table shows the licensing requirements for this feature:
Basic device management requires no license. Any feature not included in a license package is bundled with the Cisco NX-OS system images and is provided at no extra charge to you. For a complete explanation of the Cisco NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide.
Changing the Device Hostname
You can change the device hostname displayed in the command prompt from the default (switch) to another character string.
Configures the time zone. The zone-name argument is a 3-character string for the time zone acronym (for example, PST or EST). The offset-hours argument is the offset from the UTC and the range is from –23 to 23 hours. The range for the offset-minutes argument is from 0 to 59 minutes.
Exits global configuration mode.
switch# show clock
Displays the time and time zone.
copy running-config startup-config
switch# copy running-config startup-config
Copies the running configuration to the startup configuration.
Configuring Summer Time (Daylight Saving Time)
You can configure when summer time, or daylight saving time, is in effect for the device and the offset in minutes.
