Wake on LAN
UpdateEXPERT Premium software patch management can remotely turn on machines that have previously been powered off in order to complete necessary patching activities. Wake on LAN ensures a higher success rate on patching that is typically scheduled to deploy during off hours.
Benefits
Wake On LAN ensures completeness and maximum accuracy of patching; preserve business continuity across a network regardless of whether machines are powered on or off.
It is essential if you want to perform tasks to satisfy your patch management policies during non-working hours. Because your users shut down systems when they leave the office, you cannot guarantee that all machines are accessible to perform these patch tasks at the scheduled time. Many systems today offer the capability to remotely power them on using Wake on LAN technology.
Once UpdateEXPERT Premium software patch management has completed its tasks for your patch management policies, you can return the target system to its prior power state and turn it off. This capability also extends to machines that were left running prior to the patch management task.
Wake on LAN relies on features in the computer hardware to allow a system to wake up from a powered off state if a specifically formatted network packet is received by the computers NIC. The feature can be enabled or disabled through the computer's BIOS configuration and sometimes be managed through power management features of the Operating System or through the NIC driver configuration.
How it Works
Waking up machines with WOL support is done by sending a broadcast network packet to the network segment that the target system is connected to. The actual "magic packet" that is used to wake up a system is a low-level Ethernet packet that is internally addressed to the machines hardware MAC address. This means that the packet is sent to all systems within a network segment and each machine looks at the packet content to check if the content is directed to it. If a machine matches the MAC address inside the packet to its own MAC address, it sends a wake up signal to the power controller of the computers motherboard. As a result of this action the system will power up.
Once UpdateEXPERT Premium software patch management has sent the WOL request, it waits for the remote target machine to start up. If the remote system becomes available within a configurable timeout period, UpdateEXPERT Premium is able to perform the specified tasks for your patch management policies.
