PART07-NSX Series Check the integrity of the vibs on the ESXi host

In order to ensure that the relevant vibs has been successfully installed on the corresponding host, but also need to go to each host to do a verification (not necessary steps, but to develop a rigorous technical habits, you can let us less hit the wall, this cat has been countless times to our students have spoken);

In the previous Part06, already installed, after the successful installation, in Figure 01, you can clearly see the status of the relevant components:

Figure 01

After confirming this step, you can go to the CLI to check the related components. First, the state of the UWA (full name: User World Agent) needs to be verified. Since the NSX component has been successfully push on the host, a process called Netcpad will be in the running state of the system. The UWA and the control plane on the NSX controller are passed through the SSL security component. UWA is the communication intermediate between the NSX controller and the hypervisor kernel, but distributed firewall is not in this mailing list. The communication between ESXi to NSX Manager or NSX controller is UWA. UWA collects statistical information from NSX Manager via the message bus agent;

How do I see this UWA? Can be viewed through the command line, when the ESXi host push completed Vibs, under the/ETC/INIT.D directory will be a number of things called Netcpad, you can perform the following command to view:

#/etc/init.d/netcpad status

As shown in output 02, you will be prompted Netcp Agentservice is running:

Figure 02

How do I check the running status of this NETCPA? Can be viewed through the esxtop command, under the CLI of the ESXi host, when the command esxtop is executed, you can see the red box selection shown in Figure 03, a process called netcpa.42230:

Figure 03

At the same time, UWA will be responsible for maintaining the log messages in the/var/log/netcpa.log, and can execute commands at the command line:

1. #ls/var/log

You can see the message shown in 04, where you can see the Netcpa.log's true storage path:

Figure 04

The above message is a way of teaching us how to view UWA, NETCPA and other messages. The next thing to look at is the 3 vibs for NSX, namely:

· Esx-vxlan

· Esx-vsip

· Esx-dvfilter-switch-security

These packages represent several important features of NSX, which are based on their presence, and NSX can be implemented as an SDN solution;

First, perform the following command to check if the Esx-vxlan Vib is successfully installed, command:

1. #esxcli software vib get–vibname Esx-vxlan

The output results in 05 are as follows:

Figure 05

From the results shown in Figure 05, you can see the specific version number of the Vxlan component, the purpose, the Red box section describes the purpose of the component, its starting position and other messages. Seeing these messages indicates that the Esx-vxlan component was successfully installed;

Next, perform the following command to check if the Esx-vsip Vib is successfully installed, command:

1. #esxcli software vib get–vibname esx-vsip

The output results in 06 are as follows:

Figure 06

From the results shown in Figure 06, you can see the specific version number of the Esx-vsip component, the purpose, the Red box section describes the purpose of the component, its starting position and other messages. Seeing these messages indicates that the ESX-VSIP component was successfully installed. Indicates that the VIB contains the functions of DFW and NETX;

Finally, perform the following command to check if the Esx-dvfilter-switch-security Vib is successfully installed, command:

1. #esxcli software vib get–vibname esx-dvfilter-switch-security

The output results in 07 are as follows:

Figure 07

From the results shown in Figure 06, you can see the specific version number of the Esx-dvfilter-switch-security component, the purpose, the Red box section describes the purpose of the component, its starting position and other messages. Seeing these messages indicates that the Esx-dvfilter-switch-security component was successfully installed. Indicates that the VIB contains the Dvfilter-switch-security module;

To be Continued ...
