Management Ethernet and Internal Ethernet Interface Operational Mode Commands

Table 1 summarizes the command-line interface (CLI) commands that you can use to monitor and troubleshoot the management Ethernet interface and, in the case of M Series and T Series routers, the internal Ethernet interface.

On the M Series and T Series routers other than the TX Matrix Plus router and T1600 routers in a routing matrix, the JUNOS Software automatically creates the router’s management Ethernet interface, fxp0, which is an out-of-band management interface for connecting to the router, and the internal Ethernet interface, fxp1, which connects the Routing Engine to the Packet Forwarding Engine. If the platform has redundant Routing Engines, another internal Ethernet interface, fxp2, is created to connect the second Routing Engine (re1) to the Packet Forwarding Engine.

On TX Matrix Plus Routers and T1600 routers configured in a routing matrix, the JUNOS Software automatically creates the router’s management Ethernet interface, em0. To use em0 as a management port, you must configure its logical port, em0.0, with a valid IP address.

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 Software automatically creates two internal Ethernet interfaces, ixgbe0 and ixgbe1, for the two 10-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.

On J Series routers, the JUNOS Software automatically creates the router’s management Ethernet interface, fe-0/0/0, which is an out-of-band management interface for connecting to the router.
