Understanding JDM Management Interfaces
You can access JDM through the system console, a dedicated out-of-band management
interface, or an in-band management interface.

Console Interface
On disaggregated Junos OS platforms that host Juniper Device Manager (JDM), you are
placed in either the JDM shell prompt or the JDM CLI when you first connect to a device
using the device console port. You can access the JDM CLI or other VMs, including the
Junos Control Plane (JCP) CLI that is used to manage Junos OS software, from this
prompt. See “Accessing the JDM Shell, JDM CLI, and JCP Prompts in a Disaggregated
Junos OS Platform” on page 28.
Out-of-Band Management Interface
The JDM out-of-band management interface is named jmgmt0. The jmgmt0 interface
is directly connected to the dedicated Ethernet management port on the disaggregated
Junos OS platform.
The jmgmt0 interface in a disaggregated Junos OS platform is analogous to the em0,
me0, or fxp0 interfaces on a Juniper Networks switch or a router running traditional Junos
OS software. To use jmgmt0 as a management port, you must configure a logical interface
(jmgmt0.0) on it with a valid IP address. You can then connect to the management
interface over the network using utilities such as SSH or Telnet. SNMP can be used on
the management interface to gather statistics.
The dedicated Ethernet management port on the platform is shared by other compute
entities. For example, JCP uses the dedicated Ethernet management port for its
out-of-band management interface, em0, as shown in Figure 9 on page 32.
