Built-In Ethernet Port for the SRX210 Services Gateway

The SRX210 Services Gateway uses ge-0/0/0 as a management port to perform initial device setup.

Before initial configuration, when the factory default configuration is active, the device attempts to perform autoinstallation by obtaining a device configuration through all its connected interfaces, including ge-0/0/0. The services gateway acts as a DHCP client out of the built-in Ethernet ports.

If the services gateway does not find a DHCP server within a few seconds, the device acts as a DHCP server and assigns an IP address as

With the device temporarily acting as a DHCP server, you can manually configure it with the J-Web interface. Any DHCP client host, for example, a PC or laptop computer, directly connected to ge-0/0/0 receives an address on the network.

Note: The DHCP functionality for initial setup is different from the configurable DHCP server functionality of the services gateway during operation.

Once you connect your laptop or PC to ge-0/0/0, you can use a Web browser to visit the address, access the J-Web Quick Configuration Set Up page, and complete the initial configuration of the device.

After you perform the initial configuration and commit it by clicking OK on the Quick Configuration Set Up page, the configured device can no longer act as a DHCP server. Therefore, to continue using the device as a management interface you should configure the IP address of the interface as part of the initial configuration.
