![]() ![]() If there’s a DHCP server on the local Layer 2 domain, it will reply and everyone will be happy. ![]() When the client connects, it does the usual DHCP exchange by sending a broadcast DHCP discovery frame to find a DHCP server. In a typical client connection to a wired Ethernet port, the client will be a member of a VLAN based on the switch port configuration. In this article, I want to focus on understanding a few ways in which your wireless infrastructure participates in the client’s process of obtaining a DHCP address. To give you a nudge on your journey, let’s talk about Dynamic Host Configuration Protocol (DHCP) for wireless clients.ĭynamic Host Configuration Protocol (DHCP) is one of those oft-overlooked topics that you must understand for initial wireless configuration and connectivity troubleshooting. Understanding wired design topics is pretty fundamental to installing or managing any network, so it really should be on our priority list to spruce up those skills. For us wireless folks that aren’t stellar routing and switching guys, one of the most daunting network tasks is integrating our WLAN infrastructure with the existing wired infrastructure and its services.
