Networking 编辑

This section provides an overview of Citrix Hypervisor networking, including networks, VLANs, and NIC bonds. It also discusses how to manage your networking configuration and troubleshoot it.

Important:

vSwitch is the default network stack of Citrix Hypervisor. Follow the instructions in vSwitch networks to configure the Linux network stack.

If you are already familiar with Citrix Hypervisor networking concepts, you can skip ahead to Manage networking for information about the following sections:

• Create networks for standalone Citrix Hypervisor servers

• Create private networks across Citrix Hypervisor servers

• Create networks for Citrix Hypervisor servers that are configured in a resource pool

• Create VLANs for Citrix Hypervisor servers, either standalone or part of a resource pool

• Create bonds for standalone Citrix Hypervisor servers

• Create bonds for Citrix Hypervisor servers that are configured in a resource pool

Note:

The term ‘management interface’ is used to indicate the IP-enabled NIC that carries the management traffic. The term ‘secondary interface’ is used to indicate an IP-enabled NIC configured for storage traffic.

Networking support

Citrix Hypervisor supports up to 16 physical network interfaces (or up to 4 bonded network interfaces) per host and up to 7 virtual network interfaces per VM.

Note:

Citrix Hypervisor provides automated configuration and management of NICs using the xe command line interface (CLI). Do not edit the host networking configuration files directly.

vSwitch networks

vSwitch networks support open flow.

• Supports fine-grained security policies to control the flow of traffic sent to and from a VM.

• Provides detailed visibility about the behavior and performance of all traffic sent in the virtual network environment.

A vSwitch greatly simplifies IT administration in virtualized networking environments. All VM configuration and statistics remain bound to the VM even when the VM migrates from one physical host in the resource pool to another.

To determine what networking stack is configured, run the following command:

xe host-list params=software-version
