You can configure Branch Gateway to function as a DHCP (Dynamic Host Configuration Protocol) client.
DHCP client enables Branch Gateway to receive an IP address from a DHCP server, according to the DHCP client-server protocol. The DHCP server grants Branch Gateway DHCP client an IP address for a fixed amount of time, called the lease. After the lease expires, Branch Gateway DHCP client is required to stop using the IP address. Branch Gateway DHCP client periodically sends requests to the server to renew or extend the lease.
In addition to receiving an IP address, Branch Gateway DHCP client can optionally request to receive a domain name, a list of default routers, and a list of available DNS servers.
Note:
Branch Gateway can function as both a DHCP server and a DHCP client simultaneously. That is, you can connect a cable modem for an Internet connection to the WAN Fast Ethernet in order to use Branch Gateway as a DHCP client. At the same time, you can activate the DHCP server on Branch Gateway for use by clients, such as, IP phones and PCs connected to the LAN ports. The DHCP server on Branch Gateway does not serve Internet devices connected over the WAN Fast Ethernet ports.
You can also enable the DHCP client on the VLAN interface.
The DHCP client only supports IPv4.
