About the Router Details Page

From this page, network administrators can view detailed information about the hardware components and interfaces of the routers monitored by Juniper Mist Routing Assurance. You can view details of all routing engines, channelized interfaces, breakout interfaces, port summary, detailed physical inventory and cooling system components, at a glance from this page.

Juniper Mist Routing Assurance enables you to monitor the health of routers in the network by continuously observing vital router parameters like status of Ethernet ports, status of power supply units (PSU) and cooling system components in real-time.

To access this page, navigate to Organization > Inventory > Routers. Then click any router from the list of onboarded routers.

Tasks You Can Perform

You can perform the following tasks from this page:

View front panel information—Click Front Panel to view details about a router's chassis. For more information, see Front Panel.
View port information—Click Port List tab to view details of a router's ports such as port status, type, speed and so on. For more information, see Port List.
View a detailed physical inventory—Click Physical Inventory tab to view details of the hardware components and software versions which include part number, serial number, OS version and so on, in tabular format. For more information, see Physical Inventory.
View CPU utilization information—Mouse over CPU widget to view CPU utilization of a router.
View memory utilization information—Mouse over Memory widget to view memory utilization of a router.
View status of the cooling system—
- Mouse over Temp widget to view the status of router cooling system. You can view the temperature of inlet sensors, exhaust sensors, and CPU cores of the router. The temperature is displayed in degree Celsius.
- Mouse over Fans widget to view the status of fan trays in the router. The state of fan trays can be:
  - Green: Status of fan tray is OK.
  - Unlit: Fan tray is Absent.
View status of power supply modules of a router—Mouse over PSUs widget to view status of all the power supplies installed in a router. The state of the power supply units can be:
- Green: Status of the power supply is OK.
- Unlit: Power supply is Absent.
Refresh the page—Click the Refresh icon to trigger a page refresh.

Note:

The information displayed in Temp, Fans and PSUs widgets can be viewed by running the command, show chassis environment on the router's CLI.

Front Panel

The front panel Tab displays the front panel of a router chassis. You can view a router's routing engines, Ethernet ports, channelized interfaces, breakout interfaces and their supported transceivers on this tab. The name of the router is displayed on the widget header.

Figure 1: Front Panel

Click a routing engine to view its properties in the Properties widget.

Mouse over an Ethernet port to view the port's statistics such as channel port status, breakout port status, speed, profile, and so on.

Router Port Status

Table 1 describes the status of the ports on a router's front panel.

Table 1: Router Port Status
Color	State	Description
Green	On steadily	No breakout, port is up. Breakout, all lanes in the port are up.
Red	On steadily	Optics transceiver hardware failure.
Amber	On steadily	Any other fault except loss of signal (LOS) and transceiver hardware failure. Breakout, some lanes in the port are up, some lanes are down.
Off	NA	Pluggable not inserted. No breakout; Loss of signal detected. Breakout; Loss of signal on all lanes.

Router Port Statistics

Table 2 lists all the ports statistics that you can view for a given port.

Table 2: Router Port Statistics
Field	Description
Name	Name of the interface.
Status	Status of the interface. The status can be— Up: Interface is enabled and operational. Down: Interface is down because of a hardware failure.
Speed	Configured port speed.
Duplex	Connection characteristic of the port— `full-duplex`: Connection is full duplex. `half-duplex`: Connection is half duplex.
BPS	Number of bits transmitted or received each second— IN: Number of bits received per second. OUT: Number of bits transmitted per second.
Agg. Ethernet	Aggregated interface number. You can also view the Ethernet interfaces that are bundled together for an aggregated interface.
LACP State	State of the multiplexer state machine for the aggregation port in Link Aggregation Control Protocol (LACP). The state is one of the following values: Attached—Multiplexer state machine initiates the process of attaching the port to the selected aggregator. Collecting Distributing—Collecting and distributing states are merged together to form a combined state (coupled control). Because independent control is not possible, the coupled control state machine does not wait for the partner to signal that collection has started before enabling both collection and distribution. Detached—Process of detaching the port from the aggregator is in progress. Waiting—Multiplexer state machine is in a holding process, awaiting an outcome.
LACP Timeout	LACP interval configured on the port— Fast: LACP packets are exchanged every second. Slow: LACP packets are exchanged every 30 seconds.
Description	Brief description of the port.

Port List

The Port List Tab displays a wealth of information about each port of the router. You can view details such as a router's port status, port connection characteristic, port speed and so on, from this tab.

The Port List Table displays the port summary in an easy to understand tabular format. Table 3 lists all the fields in the Port List table.

You can sort the columns in the table by the header. Click any column header to sort its entries.

Table 3: Port List Table
Field	Description
Port	Name of the port.
Status	Status of the port. The status can be— Up: Interface is enabled and operational. Down: Interface is down because of a hardware failure.
Agg. Ethernet	Aggregated interface number.
Speed	Configured speed of the port. The speed is displayed in bps.
Full Duplex	Connection characteristic of the port— Tick icon—Connection is full-duplex. Cross icon—Connection is half-duplex. Blank icon—Connection information is unavailable. A blank is displayed if the port is down.
RX Bytes	Number of bytes of data received at the port.
TX Bytes	Number of bytes of data sent from the port.
Description	Brief description of the port interface which can include connectivity information.

Physical Inventory

The Physical Inventory tab displays a list of all Flexible PIC Concentrators (FPCs), PICs and fan trays installed in the onboarded router, in a tabular format. Table 4 lists all the fields in the physical inventory table.

Table 4: Physical Inventory
Field	Description
Name	Information about the router hardware.
Model	Model number of the hardware component.
Version	Revision level of the chassis component.
Serial	Serial number of the chassis component.
Part Number	Part number of the chassis component.
