When configuring the Layer 3 switch, make sure that the Vlan of the server and the Vlan of the client can communicate with each other. ![]() This is in order for the PXE signal to transfer from server’s VLAN to client’s VLAN In order to run PXE in Virtual Local Area Network (VLAN) environment, DHCP Relay require to configured at Switch if the server’s VLAN and client’s VLAN is different. Normal Spanning Tree Protocol (STP) convergence (Layer 2 convergence) time is 50 seconds and the end user traffic is blocked until Root Port and/or Designated Port reach the forwarding state. ** Spanning Tree Protocol (STP) convergence (Layer 2 convergence) happens when bridges and switches have transitioned to either the forwarding or blocking state. ![]() DHCP is used to locate the appropriate boot server or servers, with TFTP used to download the initial bootstrap program and additional files.įor a Cisco Switches, the following configuration requires to speed up Internet Protocol (IP) assignation during PXE boot.Įach of every PC connected to switch, following configuration is required: The PXE protocol is approximately a combination of Dynamic Host Configuration Protocol (DHCP) and Trivial File Transfer Protocol (TFTP), albeit with subtle modifications to both. Preboot Execution Environment (PXE) is an environment to boot computers using a network interface independently of data storage devices (like hard disks) or installed operating systems. ![]()
