这门课程《ESXi and vSphere vSwitch Config with GNS3》旨在教授如何在 GNS3 自动化环境中配置 ESXi 和 vSphere 的分布式虚拟交换机 (vDS)。 **核心内容概述：** * **分布式虚拟交换机 (vDS) 的概念：** vDS 类似于一个模板，存储在 vCenter 中。当您在 vCenter 中创建 vDS 时，所有加入该 vDS 配置的 ESXi 主机上都会自动创建相同的隐藏标准 vSwitch。 * **配置的优势：** 在 vDS 上创建的端口组（如包含 VLAN 的端口组）会在所有关联的 ESXi 主机的 vSwitch 上自动创建。这意味着您只需配置一次端口组，极大地提高了效率。 * **控制平面与数据平面：** vCenter 是 vSphere 环境的管理系统，包括 vDS 的管理。vDS 本身被视为**控制平面**。而 ESXi 主机上隐藏的标准 vSwitch 则是**数据平面**，负责实际的网络操作。 * **vCenter 的可用性：** 即使 vCenter Server 暂时不可用，网络仍然会保持工作状态，这是因为数据平面的隐藏标准 vSwitch 仍在运行。但在此期间，您无法更改 vDS 的配置，包括虚拟机重新连接到其他端口组。需要注意的是，vCenter 本身无法直接连接到 vDS。 * **VLAN 配置与连接：** 课程将重点介绍如何配置 vDS 的 DPortGroups，并将其连接到 Cisco L2 交换机的 Trunk 端口。这通过 ESXi 主机上已配置的 MS Loopback Adapters/VMNICs 完成。在 Windows 11 中配置 MS Loopback Adapters 时，无需为其分配 IP 地址。在配置 DPortGroups 时，您将指定 VLAN 映射。处于这些 VLAN 中的虚拟机将拥有与其所在的 VLAN 和 Cisco L2 交换机上配置的 VLAN 及 SVI（交换虚拟接口）相匹配的子网范围。
A distributed virtual switch is like a template stored in vCenter. When you create a distributed virtual switch in vCenter, identical hidden standard vSwitches are created on all ESXi hosts added to VDS configuration. If you create a port group for VLAN on a distributed virtual switch, the same port group will be created on all vSwitches of ESXi hosts associated to that VDS. You only need to create a port group once, which is a significant advantage. A distributed virtual switch created in vCenter is a control plane (used for management) and hidden standard vSwitches on ESXi hosts are the IO plane (responsible for network operation).vCenter is a management system for vSphere environment, including a distributed virtual switch. If, for some reason, vCenter Server is unavailable, you will not be able to change VMware distributed switch configuration, including reconnecting virtual machines to other port groups. However, even if vCenter is offline, a network will remain in a working state because hidden standard vSwitches (the IO plane) are responsible for network operation. Keep in mind that vCenter cannot be connected to a distributed virtual switch.vCenter Distributed Switch VLANs - DportGroups will Connect to the Cisco L2 Switch Trunk through the already configured MS Loopback Adapters/VMNICs and attached to the ESXi Hosts. We Dont need to assign IP Addresses for the MS LoopBac Adapters in Windows11. Since While Configuring the DPortGroups We will be specifying the VLANs to get mapped and the VMs which are going to sit in those VLANs will have their Subnet Range, Which will match with the Cisco L2 Switch VLANs and SVIs(Switch Virtual Interfaces) Configured.
