你好呀，

我是一个网络人，这是我第一次在这里发布。抱歉，如果我违反了任何论坛规则。我们与Nutanix上的Vserver主机遇到了一些问题，我想看看这里的任何专家是否可以从Nutanix站立点那里解决问题。我们将Nutanix设置为LACP，并通过使用虚拟端口通道连接到两个Nexus开关（5000）。有时，Vserver的MAC地址在其中一个开关中的ARP表上显示不完整，而不仅仅是一个Vserver。然后，我们最终意识到，如果我们关闭了交换机的一个端口，那么MAC地址在ARP表中不完整，则VSERVER立即开始工作。在我们执行没有关闭后，问题又回来了。我们从切换站点检查了问题，但找不到任何问题。有人知道这个问题可能与Nutanix有关吗？谢谢你。

    Hi there,<\/p>

    \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 I\u2019m a network guy and this is my first time post here. Sorry if I broke any forum rule. We are having some issue with vServer host on Nutanix, and I would like to see if any experts here can tell the solution of the problem from nutanix stand-point. We have nutanix setup as LACP and connects to two nexus switches(5000) by using virtual port-channel. Sometimes mac address of vServer showed incomplete on arp table in one of the switches, not only one vServer. Then we finally realized that if we shutdown one port of the switch, which mac address incomplete in arp table, the vServer started to work immediately. After we executed no shut, the issue was back again.\u00a0We checked the issue from switch stand-point, but couldn\u2019t find any issue. Is anyone know the issue can be related to Nutanix? Thank you.<\/p>","quoteUsername":"SolarPanda","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    你好，

    您是否尝试调整任何LACP参数（即超时）？

    我们打算这样做，所以我说的任何事情都用一粒盐来服用。这全都来自阅读，而不是从现在开始。我们将在本月晚些时候实施。

    我知道有一个选择将自动倒式背back设置为Active/备份|如果发生任何问题，则在Balance-TCP设置中的活动/被动（“ OVS-VSCTL设置port br0-up other_config：lacp-fallback-ab = true”）。另外，您可能必须调整时间安排（“ ovs-vsctl set port br0-up other_config：lacp time = fast”）。应该能够确认LACP（“ OVS-APPCTL键/显示BR0-UP”和“ OVS-APPCTL LACP/SHOW BR0-UP”）。

    一些好的资源是：

    Hello,<\/p>

    Have you tried adjusting any of the LACP parameters (ie timeout)?<\/p>

    We are planning on doing this so anything I say take it with a grain of salt.\u00a0 It is all from reading and not from doing at this point.\u00a0 We will be implementing this later this month.<\/p>

    I know there is an option to set auto-fallback to active\/backup | active\/passive within the Balance-tcp setup should any problems occur (\"ovs-vsctl set port br0-up other_config:lacp-fallback-ab=true\").\u00a0 Also you might have to adjust the timing (\"ovs-vsctl set port br0-up other_config:lacp-time=fast\").\u00a0 Confirmation of the LACP should be able to be achieved (\"ovs-appctl bond\/show br0-up\" and \"ovs-appctl lacp\/show br0-up\").<\/p>

    A couple of good resources are:<\/p>
