Configuring an IP address for an Eth-channel interface of a
4G modem
About obtaining an IP address for an Eth-channel interface
An Eth-channel interface can communicate with other devices only after it obtains an IP address.
You can configure an IP address for an Eth-channel interface in the following ways:
•
DHCP
—The Eth-channel interface obtains the modem's IP address as its own IP address
through DHCP. The modem's IP address is automatically allocated by the service provider.
•
Modem manufacturer's proprietary protocol
—The Eth-channel interface obtains the
modem's IP address as its own IP address through the modem manufacturer's proprietary
protocol. The modem's IP address is automatically allocated by the service provider.
•
Manual
configuration
.
The ways for the Eth-channel interface to obtain an IP address are mutually exclusive. The most
recent configuration overrides the previous one.
Restrictions and guidelines
Changing the IP address will result in dialup interruption. Immediate re-dialup upon interruption
might not be supported by service providers.
