Understanding Built-In Ethernet Ports
Note the following points about the J-SRX240 Services Gateway management port:
•
The J-SRX240 Services Gateway uses any of the ports between
ge-0/0/1
and
ge-0/0/15
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 of its connected
interfaces.
•
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 192.168.1.1/24. 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 any
of the ports between
ge-0/0/1
and
ge-0/0/15
receives an address on the 192.168.1.1/24
network.
Mapping the Chassis Cluster Ports
On the J-SRX240 Services Gateway, the following ports are not user configurable when
the services gateway is operating in chassis cluster mode.
The fxp0 port is dedicated as the out-of-band management interface for each of the
devices in the chassis cluster setup and the fxp1 port is dedicated as the chassis-cluster
control port.
Table 30 on page 72 shows the mapping of the chassis cluster ports.

Management Interface GE Ports on J-SRX240 Services Gateway
fxp0 (management port) ge-0/0/0
fxp1 (control port) ge-0/0/1
JUNOS Software automatically creates the fxp0 and fxp1 interfaces on these ports when
the J-SRX240 Services Gateway is operating in chassis cluster mode.
