Connectivity Issues

无线客户机连通性issu用户体验es whenMobility Master Virtual ApplianceandMobility Controller Virtual Applianceis used withNICNetwork Interface Card. NIC is a hardware component that allows a device to connect to the network.teaming and without configuringLACPLink Aggregation Control Protocol. LACP is used for the collective handling of multiple physical ports that can be seen as a single channel for network traffic purposes.. To resolve this issue refer toin the Appendix.

DHCP Address

Clients connected to theArubaMobility Controller Virtual Applianceare unable to get aDHCPDynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.address. This issue is resolved by implementingNICNetwork Interface Card. NIC is a hardware component that allows a device to connect to the network.teaming on vSwitch or Distributed vSwitch. For more information refer to the Appendix.

ARP问题

Scenario

ARPAddress Resolution Protocol. ARP is used for mapping IP network address to the hardware MAC address of a device.issue occurs when Promiscuous Mode is not enabled and allVLANs梵tual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.are disallowed on vSwitch.

Instructions

Enable Promiscuous Mode and allow allVLANs梵tual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.on vSwitch.

To enable Promiscuous Mode, perform the following steps:

1.Log in to vSphere ESXi Host.

2.Switch to配置tab.

3.SelectNetworkingunderHardwaresection.

4.ClickPropertiesfor a configured vSwitch.

5.Click编辑underPortstab ofvSwitch Propertieswindow.

6.Switch to安全tab invSwitch Propertieswindow.

7.SelectAcceptfrom thePromiscuous Modedrop-down list.

Enable Promiscuous Mode on all ports attached to theVM梵tual Machine. A VM is an emulation of a computer system. VMs are based on computer architectures and provide functionality of a physical computer.. If a single port is used inArubaOS, Promiscuous Mode need not be enabled.

8.ClickOK.

MAC Address Collision in a Network

A user noticesMACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network.address collision in a network due to duplicateMACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network.entries. When the duplicateMACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network.entry is detected byArubaOS, connectivity to theMobility Controller Virtual Applianceis lost. To resolve this issue, refer to the following KB article. Once the issue is resolved reboot all VMs.

Networks Cards Not Detected

When a new network card is added to the ESXi/ESX host the following symptoms might be displayed:

The new network card is not recognized by the system.

The new network card is not listed when you run the commandesxcfg-nics -l.
