Management Ethernet Interface Overview
The router’s management Ethernet interface, fxp0 or em0, is an out-of-band management interface that needs to be configured only if you want to connect to the router through the management port on the front of the router. You can configure an IP address and prefix length for this interface, which you commonly do when you first install the Junos OS:
[edit]user@host# set interfaces (fxp0 | em0) unit
0 family inet address/prefix-length[edit]user@host# showinterfaces {(fxp0 | em0) {unit 0 {family inet {address/prefix-length;}}}}
