Overview of Cisco Connected Grid Device Manager
This chapter provides an overview of the Cisco Connected Grid Device Manager (Device Manager) for Cisco 1000 Series Connected Grid Routers (CGR 1000 or router) running Cisco IOS and for the Cisco 500 Series WPAN Industrial Routers (IR500).
Application
Device Manager is a Windows-based application that field technicians can use to manage the CGR 1000 running Cisco IOS over WiFi or Ethernet. Beginning with Release 4.1, Device Manager also supports management of the IR500, which supplies RF mesh connectivity to IPv4 and serial Internet of Things (IoT) devices (for example, recloser controls, capacitor bank controls, voltage regulator controls, and other remote terminal units).
Cisco Connected Grid Network Management System (Cisco CG-NMS) manages multiple CGR 1000 and IR500 devices, whereas Device Manager connects and manages a single device at a time.
- Device Manager can manage CGR 1000 routers in Connected Grid field deployments operating with or without CG-NMS:
–
When operating with CG-NMS, a Device Manager user can retrieve work orders from the system as well as perform all supported tasks on the main page (see Figure 1-2) except as limited by the privilege level that the administrator configures on the router for that user.
– When operating without CG-NMS, the Device Manager user does not have access to work orders; however, the user can perform all supported tasks on the main page except as limited by the user’s privilege level.
- Device Manager can manage IR500 devices in Connected Grid field deployments operating with or without CG-NMS:
– When operating with CG-NMS, a Device Manager user can retrieve work orders from the system as well as perform all supported tasks on the main page (see Figure 1-4).
IR500 devices use CoAP Simple Management Protocol (CSMP) for communicating with CG-NMS. The IR500 regularly reports inventory metrics to CG-NMS using CSMP. CG-NMS stores the reported properties and metrics.
– When operating without CG-NMS, the Device Manager user does not have access to work orders. The user can view device settings and status but cannot make configuration changes or send data to CG-NMS.
Device Manager and CGR 1000
CGR 1000 routers are multi-service communications platforms designed for use in a field area network (FAN). The portfolio consists of two models–CGR 1240 and CGR 1120–both ruggedized to varying degrees for outdoor and indoor deployments. Both models are modular and support a wide-range of communications interfaces such as 2G/3G, Ethernet, and WiFi.
Device Manager connects to the CGR 1000 by using a secure Ethernet or WiFi link. (See Figure 1-1.)

This section covers the following topics:
User Interface
When you first start Device Manager, it displays the Device Manager opening page with a list of work orders, if any are available. From this page, you can connect to the CGR 1000 either with or without a work order. (See Connecting to the CGR 1000.)
After connecting to the router, Device Manager displays the Dashboard. On the left-hand side of the Dashboard, you can view the router and any installed Connected Grid modules. LEDs indicate the current state of the router and modules. You can also view the status of Ethernet ports and modules while hovering over them.
On the right-hand side of the Dashboard, you can view a graph of CPU and memory utilization. For the CGR 1240, you can view battery information.
At the top of the screen, a mini-dashboard provides additional details on the router as detailed in Table 1-1 .
For an overview of all the tasks that you can perform with Device Manager, refer to Table 1-2 .

Tasks
Device Manager displays the main page (see Figure 1-2) after securely connecting to the CGR 1000. From the Menu tabs on the main page, you can perform the following tasks as determined by your privilege level. (See User Accounts for more information about user accounts and privilege levels.) Table 1-2 lists all the tasks that a user with privilege level 15 (default privileged EXEC mode) can perform with Device Manager and provides an example of when to perform each task.
|
|
|
|---|---|
Use the Dashboard to check the status of router hardware, such as BBU (optional), power, and modules. (See User Interface.) |
|
Verify access to a device (IP address) from the CGR 1000 by using ping to check link connectivity and quality, and initiate a traceroute for an inaccessible IP address. (See Testing Connectivity.) |
|
Bring up or shut down a CGR 1000 interface and view details for an interface. (See Managing Interfaces.) |
|
Update the CGR 1000 configuration with a provided configuration file, and then reboot the router with the new configuration. (See Changing the Configuration.) |
After you install the configuration file, the router automatically reboots with the new configuration. |
Upload a copy of a software image onto the CGR 1000 for immediate installation or for a deferred update of the image. (See Updating the Firmware Image.) |
The router automatically reboots after you update the software image. |
Download and view the CGR 1000 system logs. (See Retrieving Logs.) |
|
Insert and Remove Modules from the CGR 1000 by employing a wizard that guides you through the process. (See Managing Modules.) |
|
Execute CLI commands using a console-like interface to view system information. Supported queries include verifying the system time, viewing the current router configuration, saving the current configuration, viewing the current file directory, rebooting the router, or saving the window output to a file. (See Executing Commands.) |
Device Manager and IR500
The IR500 is a distribution automation (DA) gateway that provides secure IPv4/IPv6 connectivity to DA devices such as capacitor bank controllers, reclosers, or other SCADA devices. The IR500 connects to DA devices using serial ports (RS232/RS485) and/or an Ethernet port using IPv4. The IR500 provides remote connectivity to serial DA devices over CG-Mesh by transporting serial data over TCP/IP. The IR500 also provides remote connectivity to IPv4 DA devices over the IPv6-based CG-Mesh by using Mapping of Address and Port using Translation (MAP-T). The IR500 performs NAT44 translation to translate private IPv4 addresses used by DA devices connected to the Ethernet port to public IPv4 addresses used with MAP-T.
For more information about MAP-T, see Cisco IR 500 Series WPAN Gateway and Range Extender Installation and Configuration Guide.
Figure 1-3 shows the IR500 in a CG-Mesh deployment.

Certificates
A valid X.509 certificate is required for Device Manager to connect to the CGR 1000 or to the IR500.
You can import certificates through the Device Manager opening page. (See Importing Certificates.)
Work Orders
When you first start Device Manager, it displays the Device Manager opening page, which lists available work orders. On this page, you can view and select work orders for CGR 1000 routers and 1R500 DA gateways and synchronize with Cisco CG-NMS to download work orders. (See Managing Work Orders.) Device Manager needs to be connected to CG-NMS only to download and update the work orders.
User Accounts
The CG-NMS administrator creates user accounts for the field technicians who use Device Manager to download work orders from CG-NMS. For more information, see Cisco Connected Grid Network Management System User Guide, Release 2.1.
The user privilege level configured on the CGR 1000 also authorizes the user to perform tasks on the CGR 1000 using Device Manager. The default configuration for Cisco IOS software-based networking devices uses privilege level 1 for user EXEC mode and privilege level 15 for privileged EXEC. The commands that you can run in user EXEC mode at privilege level 1 are a subset of the commands that you can run in privileged EXEC mode at privilege 15. (See Configuring Security with Passwords Privileges and Logins for more information.)
The following user accounts are provisioned at the factory:
- username cgdm-viewer-t privilege 2 token
- username cgdm-admin-t privilege 15 token
- username cgdm-viewer privilege 2
- username cgdm-admin privilege 15
Table 1-5 shows the required privilege level for the listed tasks.
