When the Device Functions as the Access Device, It Takes a Long Time for Users to Obtain IP Addresses Through DHCP? Why?

By default, STP is enabled on the device used as the user access device (WAN-side interface connects to the Internet and LAN-side interface connects to the internal network). The device interface is in Discard state 30s after users connect to the device. DHCP Request packets are discarded. DHCP packets are processed after 30s.

It is recommended that STP be disabled to prevent network flapping caused by slow STP convergence.
