亲爱的专家，我的Nutanix环境如下：4块Nutanix（8个节点）连接到Nexus访问开关，带有10G SPF电缆。管理程序：VMware 5.5问题：从vCenter中，我们检测到主机随机断开连接。vCenter成为悬挂的解决方法：ping不断在主机上。结果没有数据包掉落，请您建议您需要做什么，hamballi

hamballi您是否在vCenter，ESXI主机，UVM上部署了多个VLAN？
请在ESXI和Nexus上发布您的网络配置
Hamballi<\/a> have you deployed multiple vlan on vCenter, ESXi host, UVM ?

Nutanix在FEX开关上的运行不佳，例如Nexus 2000系列。另一个问题是您的vSphere 5.5是否已更新为5.5更新3B？我在更新3A上的5.5个主机中有一个断开问题。

\nNutanix doesn't work well on FEX switches e.g. Nexus 2000 series. Another problem is whether your vSphere 5.5 is it updated to 5.5 Update 3b? I have this disconnection issue on some of my 5.5 hosts which are on Update 3a.","quoteUsername":"renny-lui","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

hamballi- 您可以打开支持票吗？将Portal.nutanix.com用于NX或SX系列硬件，以及Dell XC或Lenovo HX的相应OEM支持网站。

也就是说，我们确实有一个针对Nexus开关的推荐开关配置文档，请在此处发布：https://portal.nutanix.com/#/page/kbs/details?targetId=ka03200000000tt4kcag

听起来，开关的配置方式与主机上的vswitches配置之间的配置方式可能不匹配。

例如，如果您在SwitchPorts上设置了Cisco VPC，但是在ESXI侧没有设置LACP或静态EtherChannel，则会引起您所描述的问题。

Hamballi<\/a> - Can you please open up a support ticket? Use portal.nutanix.com for NX or SX series hardware, and the respective OEM support site for Dell XC or Lenovo HX.

\nThat said, we do have a recommended switch configuration document for Nexus switches, posted here: https:\/\/portal.nutanix.com\/#\/page\/kbs\/details?targetId=kA032000000TT4kCAG<\/a>
\n
\nIt sounds like there might be a mismatch between how the switch is configured, and how the vSwitches on the host are configured.
\n
\nFor example, if you've set up Cisco VPC on the switchports, but have not setup LACP or static etherchannel on the ESXi side, it will cause problems like you describe.","quoteUsername":"Jon","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

不幸的是，由于某些内部问题，我没有对其进行测试。对5.5更新3B进行修补的建议来自VMware支持。
