In Juniper Networks Mist AI Wireless, Service Level Expectations (SLEs) are used to measure and assure real user experience across the wireless network. Each SLE is built on specific classifiers, which break down failures into root causes such as DHCP, DNS, authentication, RF conditions, or application issues. Understanding which SLEs rely on DHCP classification is essential for accurate troubleshooting.
The two Wireless Assurance SLEs that include a DHCP classifier are Successful Connects and Time to Connect.
The Successful Connects SLE measures whether client devices are able to complete the full connection process successfully. This process includes association, authentication, and critically, DHCP address assignment. If a client fails to obtain an IP address, the connection is considered unsuccessful, and the failure is explicitly classified as a DHCP issue within this SLE.
The Time to Connect SLE measures how long it takes for a client to connect from the moment it initiates association until it is fully usable on the network. One of the key components of this timeline is the DHCP transaction time. Slow DHCP responses, retransmissions, or server delays directly increase the overall connection time, and Mist classifies these delays under DHCP within the Time to Connect SLE.
The other options are incorrect for the following reasons:
Roaming SLE focuses on re-association, authentication, and mobility events, not DHCP, since IP addressing is typically retained during roaming.
Coverage SLE evaluates RF signal strength, SNR, and cell overlap, with no dependency on DHCP.
Throughput SLE measures data transfer performance after connectivity is established and does not analyze DHCP behavior.
Therefore, the correct answer is Successful Connects and Time to Connect, as both SLEs directly depend on and classify DHCP-related performance and failures within Mist Wireless Assurance.
