•mgmt0 Interface

•Device Hostname

•Message-of-the-Day Banner

•Device Clock

•Time Zone and Summer Time (Daylight Savings Time)

•User Sessions

•Virtualization Support

mgmt0 Interface

The mgmt0 interface on Cisco NX-OS devices provides out-of-band management, which enables you to manage the device by its IPv4 or IPv6 address. The mgmt0 interface uses 10/100/1000 Ethernet.

For detailed information on configuring interfaces, see the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 4.0 and the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration Guide, Release 4.0.

Device Hostname

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.

Message-of-the-Day Banner

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.

Device Clock

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 4.0.

Time Zone and Summer Time (Daylight Savings Time)

You can configure the time zone and summer time (daylight savings 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).

User Sessions

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 7000 Series NX-OS Security Configuration Guide, Release 4.0.

Virtualization Support

Basic device management is local to the virtual device context (VDC). The mgmt0 interface exists in the management virtual routing and forwarding instance (VRF) and is accessible from any VDC. You can configure a unique IP address for the mgmt0 interface in each VDC.

For more information on VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 4.0. For more information on VRFs, see the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration Guide, Release 4.0.

Licensing Requirements for Basic Device Management

The following table shows the licensing requirements for this feature:

Product
License Requirement

NX-OS

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 NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide.


Configuring the mgmt0 Interface

You can configure the mgmt0 interface on your Cisco NX-OS device.

BEFORE YOU BEGIN

Ensure that the management Ethernet (MGMT ETH) port on the active supervisor module is connected the network (see the hardware installation guide for your device).

For the default VDC, log in to the console port.

For non-default VDCs, log in to the default VDC and use the switchto vdc command.
