Summary
In this session, we delve into the functionality of the Wake-on-LAN (WoL) feature available in System Center Configuration Manager (SCCM). This feature allows administrators to remotely wake up computers that are in sleep mode or shut down, provided the Ethernet card is still active. This is particularly useful for deploying applications outside office hours when machines are typically inactive.
Highlights
- 💡 Wake-on-LAN (WoL) Feature: Enables waking up machines remotely to facilitate tasks such as application deployment when users are not in the office.
- 🔄 Magic Packet Functionality: WoL sends a special network message, known as a magic packet, to interact with the machine's MAC address, waking it up.
- 📡 Unicast vs. Broadcast:
- Unicast: Sends a magic packet to a single machine.
- Broadcast: Sends a magic packet to all machines within a subnet, often blocked by network teams.
Key Insights
- 🛡️ Prerequisites: Ensure your hardware supports 802.1 network authentication and has the necessary configurations. The DHCP lease duration should not be set to infinity.
- 🔧 Security Permissions: Notification resources under the collections category must be enabled for WoL functionality.
- ⚙️ Configuration Process:
- Access the SCCM console and navigate to the site properties.
- Enable the WoL feature by selecting the unicast or broadcast method based on your network setup.
- Configure transmission settings, including maximum wait time and UDP port settings.
- 🚀 Practical Demonstration: The session includes a demo of turning a machine on using WoL, showcasing the feature's efficacy.
Conclusion
The Wake-on-LAN feature in SCCM is a powerful tool for IT administrators seeking to optimize network management and application deployment. By understanding and configuring the necessary settings, this feature can significantly enhance operational efficiency.
