How to Set Up Out-of-Band Remote Management on Junos Devices

Out-of-band management is handled through special management interfaces on Juniper Networks devices. These interfaces are Fast Ethernet interfaces located on the front of all Juniper Networks devices. They’re designed so that traffic that arrives on these interfaces does not get routed on other network interfaces on the router. This setup separates management traffic and network traffic.

To connect your out-of-band interface to your management network, follow these steps:

1. Connect an Ethernet cable from your device’s out-of-band interface to your management network (typically a switch).

   
   



2. When your link lights are up, configure the IP address.

   
   

   The out-of-band management interfaces on Juniper Networks routers are named fxp0 on M-, MX-, and T-series devices. On these product lines, the interface settings are configured under the interface name fxp0.

   
   

   On J-series devices, the management interfaces are named fe-0/0/0. Interface settings are configured under either fxp0 or fe-0/0/0. However, the router architecturally recognizes the J-series management interface as fe-0/0/0 and uses that name when reporting any interface information via operational commands. Therefore, using the fxp0 name when configuring J-series management interfaces is confusing; instead, use the fe-0/0/0 name.

   
   



3. To configure the management interface, simply set the IP address on the interface:

   
   

interfaces {
  fe-0/0/0 {
    unit 0 {
      family inet {
        address 192.168.71.246/32;
      }
    }
  }
}
