Built-In Ethernet Port for the SRX 210 Services Gateway

The built-in Gigabit Ethernet ports, ge-0/0/0 through ge-0/0/1, on the front panel of the SRX 210 services gateway are the ports through which you perform initial device setup. The examples in this section use the ge-0/0/0 port as the management interface, but you can use any built-in Ethernet port for management. After the initial configuration is complete, you can attach the built-in Ethernet port that you are using for management purposes to the management network.

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, it sets the address of the ports as shown in Table 1.

Table 1: Gateway Port Settings




Note: The services gateway becomes a DHCP server out of the ge-0/0/0 port.

ge-0/0/1 (if used)

fe-0/0/2 through fe-0/0/7 (if using Fast Ethernet ports as management ports) through

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 Apply or 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.
