FAQ-A Directly Connected Device Cannot Be Pinged or A Client Obtains an IP Address Slowly Using DHCP. How Is This Problem Solved

Issue Description
A Directly Connected Device Cannot Be Pinged or A Client Obtains an IP Address Slowly Using DHCP. How Is This Problem Solved?
Solution
STP prevents loops on Layer 2 networks. By default, STP is enabled on the AR router. When the AR router functions as the user access device (the WAN-side uplink connects to the Internet and the LAN-side downlink connects to the internal network), loops do no occur. If STP is enabled, network flapping may occur due to port blocking or slow STP convergence. As a result, device functions are affected. It is recommended that the stp disable command be used in the system view to disable STP.
