The management interface “mgmt0” is the only interface allowed to be part of this VRF.The philosophy beyond Management VRF is to provide total isolation for the management trafficfrom the rest of the traffic flowing through the box by confining the former to its own forwarding table.In this step we will:- Verify that only the mgmt0 interface is part of the management VRF- Verify that no other interface can be part of the management VRF- Verify that the default gateway is reachable only using the management VRF如果想Ping 带外网管的网关等地址必须在Ping命令后面加上vrf managementping 10.2.8.1 vrf management划分Nexus 7010 VDCVDC是Nexus7000系列的特色功能。
通过将物理机箱划分为多个逻辑交换机，核心交换机区域将可以获得多台物理隔离的高性能交换机。
VDC具有完全隔离的路由表，VRF和接口，因此可以获得真实交换机属性的配置。
VDC的资源是占用全局机箱的，因此在必要的时候，需要通过调整VDC资源配置来进行VDC功能和性能的调整。
所有进入VDC的接口和资源都不能被其他VDC或者缺省VDC使用。

If such behavior is undesirable, make sure to allocate all interfaces on the same port ASIC to the same VDC.To see how the interfaces are mapping to the port ASIC, use this command:slot slot_number show hardware internal dev-port-map 这个命令没有帮助，需盲打copy running-config startup-config vdc-all通过命令可以查看当前VDC的数量和状态。
