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 Software:
[edit]
user@host# set interfaces (fxp0 | em0) unit 0 family inet address/prefix-length
[edit]
user@host# show
interfaces {
(fxp0 | em0) {
unit 0 {
family inet {
address/prefix-length;
}
}
}
}
On routers with multiple Routing Engines, each Routing Engine is configured with a
separate IP address for the management Ethernet interface. To access the master
Routing Engine, you must know which Routing Engine is active and use the
appropriate IP address.
Optionally, for consistent access to the master Routing Engine, you can configure
an additional IP address and use this address for the management interface regardless
of which Routing Engine is active. This additional IP address is active only on the
