SRX 210 Services Gateway Supported Autoinstallation Interfaces and Protocols

Autoinstallation provides automatic configuration for a new services gateway that you connect to the network and turn on

Before autoinstallation on a services gateway can take place, the device must acquire an IP address. The protocol or protocols you choose for IP address acquisition determine the device interface to connect to the network for autoinstallation. The device detects the connected interface and requests an IP address with a protocol appropriate for the interface. Autoinstallation is supported over an Ethernet LAN interface or a serial LAN or WAN interface. Table 1 lists the protocols that the services gateway can use on these interfaces for IP address acquisition.

Table 1: SRX 210 Services Gateway Interfaces and Protocols for IP Address Acquisition During Autoinstallation

Interface and Encapsulation Type

Protocol for Autoinstallation

Ethernet LAN interface with High-level Data Link Control (HDLC)

DHCP, BOOTP, or Reverse Address Resolution Protocol (RARP)

Serial WAN interface with HDLC

Serial Line Address Resolution Protocol (SLARP)

Serial WAN interface with Frame Relay


If the server with the autoinstallation configuration file is not on the same LAN segment as the new services gateway, or if a specific device is required by the network, you must configure an intermediate device directly attached to the new device, through which the new device can send Trivial File Transfer Protocol (TFTP), BOOTP, and Domain Name System (DNS) requests. In this case, you specify the IP address of the intermediate device as the location to receive TFTP requests for autoinstallation.
