Accessing the Virtual Chassis Through the Management Interface

The management Ethernet interface (fxp0) on an MX Series router is an out-of-band management interface, also referred to as a management port, that enables you to use Telnet or SSH to access and manage the router remotely. You typically configure the management interface with an IP address and prefix length when you first install Junos OS.

You can configure a management Ethernet interface in one of two ways to access an MX Series Virtual Chassis:

  • To access the Virtual Chassis as a whole, configure a consistent IP address for the management interface using the master-only option. You can use this management IP address to consistently access the master (primary) Routing Engine in the master router (protocol master) for the Virtual Chassis.
  • To access a specific Routing Engine in an individual member router of the Virtual Chassis, configure an IP address for one of the following MX Series Virtual Chassis configuration groups:
    • member0-re0
    • member0-re1
    • member1-re0
    • member1-re1

Best Practice: For most management tasks, we recommend that you access the Virtual Chassis as a whole through a consistent management IP address. For troubleshooting purposes, however, accessing a specific Routing Engine in an individual member router may be useful.

To access an MX Series Virtual Chassis through the management Ethernet interface, do one of the following:

  • Configure a consistent management IP address that accesses the entire Virtual Chassis through the master Routing Engine in the Virtual Chassis master router.
    {master:member0-re0}[edit] user@host# set interfaces fxp0 unit 0 family inet address ip-address/prefix-length master-only

    For example, to access the entire Virtual Chassis via management IP address 10.4.5.33/16:

    {master:member0-re0}[edit] user@host# set interfaces fxp0 unit 0 family inet address 10.4.5.33/16 master-only
  • Configure a management IP address that accesses a specified Routing Engine in an individual member router in the Virtual Chassis.
    {master:member0-re0}[edit groups] user@host# set membern-ren interfaces fxp0 unit 0 family inet address ip-address/prefix-length

    For example, to access the Routing Engine installed in slot 1 of member router 1 (member1-re1) in the Virtual Chassis:

    {master:member0-re0}[edit groups] user@host# set member1-re1 interfaces fxp0 unit 0 family inet address 10.4.3.145/32
