Note

The Management interface will reside on the adapter.

Procedure

1.

Log in to the vSphere Web Client.
2.

In the navigation pane, right-click the virtual machine you've created, then choose Power > Power Off.

3.

Right-click the virtual machine and then choose Actions > Edit Settings.
4.

Select the Virtual Hardware tab. Click Add New Device, and then choose Network Adapter.
5.

In the drop-down list for the New Network field, click Browse.
6.

In the Select Network dialog box, choose the network to connect to your virtual appliance's Management interface, and then click OK.
7.

In the Adapter Type field's drop-down list, choose VMXNET3 and then click OK.
8.

In the navigation pane, right-click the virtual machine, and then choose Power > Power On.

9.

Do one of these tasks:

  • If you haven't done so already, configure the virtual appliance using one of the available configuration wizards or the CC VA Launcher.

  • If you've already configured the virtual appliance, proceed to the next step.
10.

After Catalyst Center on ESXi comes up, run the Configuration wizard to configure the settings for the Management interface:

  1. Open a terminal window to the virtual machine. Run the sudo maglev-config update command.

    The Configuration wizard opens and displays the settings that are already configured for the appliance's Enterprise interface.

  2. Click next>>.

    The wizard now displays the settings that are already configured for the appliance's Intracluster interface.

  3. Click next>>.

  4. For the Management interface (NETWORK ADAPTER 3) you created, enter the required values for these parameters, and then click next>>:

    • Host IPv4/IPv6 Address field: Enter the IP address for the Management interface.

    • IPv4 Netmask/IPv6 Prefix Length field: Enter the netmask for the interface's IP address.

    • Default Gateway IPv4/IPv6 Address field: Enter the default gateway IP address to use for the interface.

    • IPv4/IPv6 Static Routes field: Enter one or more static routes in this format, separated by spaces: <network>/<netmask>/<gateway>.
