Cisco Nexus 7000 Series Configuring

Virtualization Support for DNS Clients
Cisco NX-OS supports multiple instances of the DNS clients that run on the same system. You can configure
a DNS client in each virtual device connect (VDC).You can optionally have a different DNS client configuration
in each virtual routing and forwarding (VRF) instance within a VDC. By default, Cisco NX-OS places you
in the default VDC and default VRF unless you specifically configure another VDC and VRF. See the Cisco
NX-OS Virtual Device Context Configuration Guide .
Licensing Requirements for DNS Clients
This feature does not require a 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.
Prerequisites for DNS Clients
•
You must have a DNS name server on your network.
•
If you configure VDCs, install the Advanced Services license and enter the desired VDC (see the Cisco
NX-OS Virtual Device Context Configuration Guide).
Guidelines and Limitations for DNS Clients
•
You configure the DNS client in a specific VRF. If you do not specify a VRF, Cisco NX-OS uses the
default VRF.
•
If you are familiar with the Cisco IOS CLI, be aware that the Cisco NX-OS commands for this feature
might differ from the Cisco IOS commands that you would use.
