Testing connectivity

As we know that our three-tier application, web, app, and DB, is connected to logical switches, let's do some basic testing to confirm their connectivity:

1. Firstly, go ahead and power on those machines.

2. Click the vSphere Web Client home icon.

3. On the vSphere Web Client home tab, click the Inventories | VMs and Templates icon.

4. Expand the VMs and templates inventory tree and power on each of the following virtual machines found in the discovered virtual machine folder:

   • web-sv-01a

   • web-sv-02a

   • app-sv-01a

   • db-sv-01a

   

5. To power on a virtual machine, select the virtual machine in the inventory, then select Power On from the Actions drop-down menu.

6. Once the machines are powered on, we will go ahead and record their IP address:

   • web-01a: 172.16.10.11

   • web-02a: 172.16.10.12

   • app-01a: 172.16.20.11

   • DB-01a: 172.16.30.11

We now do a simple ping test between web-01a and app-01a as shown in the following screenshot:

Why do we have 100% packet loss when we ping web-01a (172.16.10.11) and app...
