PXE Everywhere client requirements

Information that will help you design and plan the implementation of PXE Everywhere in your organization. This includes all the prerequisites and dependencies, which are necessary to install 1E Client with the PXE Everywhere Agent client module enabled.

For a full understanding of PXE Everywhere features and their configuration, please refer to Introducing PXE Everywhere documentation.

PXE Everywhere infrastructure dependencies

PXE Everywhere helps with OS Deployment. The PXE Everywhere Agent is a lightweight PXE service deployed throughout the network, responding to PXE requests on local subnets. Local Agents elect which one will respond to the original PXE request, and communicate with PXE Everywhere Central to determine what to do next, by asking Configuration Manager. If the original PXE client has been assigned a Task Sequence, then the Agent provides the associated boot image to the local PXE client, which can then start the Task Sequence. Boot images will have been previously deployed to Agents, providing the reassurance there will always be a local Agent capable of quickly responding with the relevant boot image. It also means you can deploy a PXE solution without needing to configure routers to support DHCP forwarding to a central PXE server. Please refer to Introducing PXE Everywhere documentation for more details.

PXE Everywhere does not depend on Content Distribution but is often used with Content Distribution, which helps with the distribution of PXE boot images via Configuration Manager, which further reduces the impact of network traffic on the WAN.

Introducing 1E Client Deployment Assistant is the recommended method of using Configuration Manager to deploy 1E Client to client computers. CDA is necessary if you want to include a boot image in the same deployment as the 1E Client.

PXE Everywhere also works in environments that use DHCP Snooping, as described in DHCP Snooping. This requires the following configuration changes:

  • Install one or more PXE Everywhere Responders, typically on server OS in the central network - Responders only communicate with Agents, they do not communicate with the PXE Everywhere Central server or with Configuration Manager.

  • Authorize the Responders to respond to PXE requests.

  • Configure DHCP Relays (IP helpers) on routers to forward DHCP/PXE request packets to the PXE Everywhere Responder(s) in addition to any DHCP Relays you already have configured for the DHCP server(s).

  • Configure PXE Everywhere Agents to listen on port 2067 (default) instead of port 67.
