Junos OS Interfaces Command Reference - Juniper Networks

TX Matrix Plus Router Internal Ethernet Interfaces
On a TX Matrix Plus router, the Routing Engine (RE-TXP-SFC) and Control Board
(TXP-CB) function as a unit, or host subsystem. For each host subsystem in the router,
the Junos OS automatically creates two internal Ethernet interfaces, ixgbe0 and ixgbe1,
for the two 10-Gigabit Ethernet ports on the Routing Engine.
When you enter the show interfaces command on a TX Matrix Plus router, the internal
Ethernet interfaces (and logical interfaces) are displayed:
user@host> show interfaces ?
...
ixgbe0
ixgbe0.0
ixgbe1
ixgbe1.0
...

T1600 Routers (Routing Matrix) Internal Ethernet Interfaces
On a T1600 router configured in a routing matrix, the Routing Engine (RE-TXP-LCC) and
Control Board (LCC-CB) function as a unit, or host subsystem. For each host subsystem
in the router, the Junos OS automatically creates two internal Ethernet interfaces, bcm0
and em1, for the two Gigabit Ethernet ports on the Routing Engine.
For more information about the management Ethernet interface and internal Ethernet
interfaces on a TX Matrix Plus router and T1600 routers configured in a routing matrix,
see the Junos Network Interfaces Configuration Guide.
The Junos OS automatically creates the router’s management Ethernet interfaces,
ge-0/0/0 through ge-0/0/3, which are out-of-band management interfaces for connecting
to the router. To use any of these interfaces as a management port, you must configure
a corresponding logical interface, such as ge-0/0/0.0, with a valid IP address. When you
enter the show interfaces command, the management Ethernet interfaces (and logical
interfaces) are displayed:
user@host> show interfaces
...
ge-0/0/0
ge-0/0/0.0
...
The Junos OS internally generates the nonconfigurable interfaces described in Table 4
on page 10.

NOTE: M Series and T Series services interfaces are indicated by
type-fpc/pic/port, whereas J Series services interfaces use the type-pim/0/port
syntax.
