AIX and Solaris: Start up the VEN.
AIX and Solaris: Shut down the VEN and send a Goodbye message.
Start Up VENs
The VEN starts when the workload is booted from the system boot files. The VEN can also be started manually.
Automatic Startup
The VEN starts when the workload is booted from system boot files:
Platform | Command | Notes |
|---|---|---|
Linux/AIX/Solaris | /etc/rc.d/init.d/illumio-ven Or /etc/init.d/illumio-ven | Installs firewall kernel modules if necessary, sets firewall to the desired state. |
CentOS/RHEL 7+, starting from 19.3.2 /usr/lib/systemd/system/illumioven.service | Initializes and starts the daemon processes needed for VEN operation. ImportantThis command is only supported in Illumio Core 19.3.2-VEN and later. | |
Windows | None needed. | The Service Control Manager (SCM) starts all VEN services at boot. |
Manual Startup
The VEN can also be started manually with illumio-ven-ctl start.
Platform | Command |
|---|---|
Linux/AIX/Solaris/RHEL/CentOS | /opt/illumio_ven/illumio-ven-ctl start |
Windows | C:\Program Files\Illumio\illumio-ven-ctl.ps1 start |
Shut Down VENs
At shutdown, the VEN sends a “goodbye” message to the PCE. The PCE marks the workload as offline and initiates a policy recomputation. After the new policy is distributed throughout the network, the workload without the VEN is effectively isolated from the network.
