Can a downstream terminal connected to an AR obtain an IP address through DHCP

1

A downstream terminal connected to the AR obtain an IP address through DHCP in either of the following situations:
- The AR is configured with the DHCP server function. By default, an AR is not configured with the DHCP server function.
- Another DHCP server exists on the network and there is a reachable route from the terminal to the DHCP server.
Otherwise, the downstream terminal connected to the AR cannot obtain an IP address through DHCP.

Can terminals connected to S series switches obtain IP addresses through DHCP
For S series switches excluding the S1700, terminals connected to switches (enabled to obtain IP addresses through DHCP) can obtain IP addresses through DHCP when either of the following conditions is met: - The switch is configured with the DHCP server function. (By default, a switch is not configured with the DHCP server function.) - Another DHCP server is deployed on the network and there is a reachable route from the terminal to the DHCP server.

Can clients connected to S series switch obtain IP addresses through DHCP
DHCP-enabled terminals that are connected to S series switches except S1700 switches can obtain IP addresses from DHCP servers when either of the following conditions is met: - The DHCP server function has been enabled on the switches. (By default, the DHCP server function is disabled on a switch.) - A DHCP server is available on the network and reachable to the terminals.

An AP fails to obtain an IP address through DHCP
Perform the following steps to locate the fault: 1. Check whether the AP is configured to obtain an IP address through DHCP. 2. Check whether the Layer 2 link between the AP and DHCP server is working properly. 3. Run the display ip pool name ip-pool-name used command on the DHCP server to check whether the AP has obtained an IP address.

A user on an AR waits for a long time to obtain an IP address through DHCP
When the AR is used as the user access device (the WAN uplink interface connects to the Internet and the LAN downlink interface connects to the intranet), STP is enabled by default. After a user connects to an AR, the interface is in Discarding state in the first 30s. DHCP Request messages are discarded. After 30s, DHCP messages can be exchanged. You are advised to enable STP to prevent network flapping caused by STP convergence.
