The Cisco ASR 9000 nV satellite feature set allows one or more smaller satellite switches to be interconnected with an Cisco ASR9000 device to form a single, combined access, aggregation and edge system.
Cisco EPN Manager supports Cisco ASR 9000v, Cisco ASR 901, Cisco ASR 901S and Cisco ASR 903 devices as satellites. The Cisco ASR 9000v is a dedicated satellite switch that can only be used in nV satellite mode along with an Cisco ASR 9000 device. The Cisco ASR 901 and Cisco ASR 903 switches are “dual mode” switches. This means that they can operate both as standalone switches or as satellite switches within an nV system with an Cisco ASR 9000 device (in which case they are completely managed and controlled by the master Cisco ASR 9000).
The satellite feature allows for both redundant and non redundant interconnections between the satellite switches and the master Cisco ASR 9000s. The access side Ethernet ports of the satellite switches appear within the control and management planes of the host master Cisco ASR 9000 just like locally connected Ethernet ports. All features that can be configured on the host Cisco ASR 9000 can also be configured and executed identically on satellite located ports. Effectively the satellite switches are virtual line cards of the host Cisco ASR 9000. Chassis management functions of the satellites such as software upgrades, inventory and environmental monitoring of hardware sensors (voltage, temperature etc) on the satellites are also seamlessly integrated into the same functions of the host Cisco ASR 9000, just like any other line card of the host Cisco ASR 9000 chassis.
Cisco EPN Manager supports the following types of nV Satellite configurations:
Satellites are not displayed in the Network Discovery page (Cisco EPN Manager does not support satellite device management operations from that page.
) becauseSatellites can only belong to Location groups because, as network nodes, they are normally managed according to location. In addition, if you add a host device to a group, its satellites are not automatically added to the group unless the group meets the following guidelines.
The following are the minimum device and device operating system requirements for the nV satellite feature set.
Additional support may be available. For more information see the Cisco Evolved Programmable Network Manager Supported Devices.
The Satellite 360 view is a popup window that provides quick information about a satellite device, its inventory, and its status. This includes device alarms, modules, interfaces, and hosts.
The Satellite 360 view provides general satellite device information at the top of the view, and more detailed interface information in tabs in the lower part of the view.

Description |
General information |
The satellite device type and name, status, last configuration change, and last inventory collection, |
Modules |
Modules that are configured on the satellite device, including their name, type, state, ports, and location. |
Interfaces |
Name, operational and admin status for each associated satellite device . Also provide a launch point for the Interface 360 view. |
Hosts |
Name, IP address, and role (Active or Standby) of host devices that are connected to the satellite. |
You can visualize the Cisco ASR 9000 host-satellite topologies and see, at a glance, whether there are active alarms on the host or satellites. From the topology map you can drill down to get further information about the host and satellite devices.
You can easily identify a satellite in the map by its label which includes the satellite ID and the IP address of the Cisco ASR 9000 host.
Note | To see the links between the devices in the satellite topology, you must enable the Inter-Chassis Control and ICCP links in the Link Types filter (top right corner above the map). ICCP protocol is used for host to host links. |
To view Cisco ASR 9000 host-satellite topologies in the map:
Step 1 | Choose Maps > Network Topology in the left navigation pane. |
Step 2 | From the Groups pane on the left, select the group that contains the Cisco ASR 9000 host and satellites. The topology map displays all the devices in the selected group. |
Step 3 | Locate the host or one of the satellites in the map. |
Step 4 | To display the links between host and satellites: |
Step 5 | Click a satellite to launch a popup showing the satellite ID as well as the ID of the active and standby hosts. |
Step 6 | Click View 360 in the popup to see more details about the satellite and its hosts in the Satellite 360 view, as described in Identify the Satellites Connected to a Cisco ASR 9000 Host. |
The Device 360 view for a selected Cisco ASR 9000 host contains information about the device itself as well as about the satellites connected to the host.
To identify the satellites connected to a Cisco ASR 9000 host:
Usually the links in the map will clearly show the satellite topology including the host and the connected satellites. If for some reason the satellites are shown without links, it is easy to identify the hosts with which a satellite is associated.
To identify the hosts connected to a satellite:
Step 1 | Choose Maps > Network Topology in the left navigation pane. |
Step 2 | From the Device Groups pane on the left, select the group that contains the Cisco ASR 9000 host and satellites. The map displays all the devices in the selected group. |
Step 3 | Click a satellite device, identified by its label which begins with Satellite ID. |
Step 4 | In the
displayed popup, click
View
360 to launch the Satellite 360 view.
The Hosts tab in the Satellite 360 view lists the host devices to which the satellite is connected and their role, either active or standby. |
When a fault occurs on a satellite, Cisco EPN Manager associates (localizes) the fault to either the host device or satellite device depending on the fault type.
If an alarm occurs on dual-homed satellite, the alarm is duplicated, with one alarm on the active host and another on the standby host.
In the topology map, you will see an alarm badge overlaid on the alarm source: the satellite device, the host device, or the link between the satellite and host device.
If there are several alarms on the same entity, the alarm badge severity represents that of the most severe alarm.
Right-click the alarmed entity to display a popup that shows the count of all active alarms related to the entity. Link-related alarms, such as Link Down, generate an alarm badge on the relevant link in the topology map.
To find out which objects are affected by the device alarms, click View 360 from the popup menu and check the Affected Objects column. If you want to view details about a specific alarm, click the alarmID hyperlink.
To get satellite alarm information from the Alarm table, choose
, then click the tab.Cisco EPN Manager lists the host device as the Failure Source. The Satellite ID and Location fields identify the satellite source.
nV Edge is a feature where two or more Cisco ASR 9000 Series Router chassis are combined to form a single logical switching or routing entity. This allows you to operate two Cisco ASR 9000 Series Router platforms as a single virtual Cisco ASR 9000 Series system. Effectively, they can logically link two physical chassis with a shared control plane, as if the chassis were two route switch processors (RSPs) within a single chassis.
There are two types of links in the nV edge topology:
The following are the minimum device and device operating system requirements for nV edge:
Additional support may be available. See the Cisco Evolved Programmable Network Manager Supported Devices.
The nV edge cluster is represented in the topology map as a single object consisting of two linked chassis, one primary and one backup.
To view the Cisco ASR 9000 nV Edge topology in the map:
Step 1 | Choose Maps > Network Topology in the left navigation pane. |
Step 2 | From the Groups pane on the left, select the group that contains the Cisco ASR 9000 cluster. The topology map displays all the devices in the selected group. |
Step 3 | Click the primary or backup chassis. Note that both chassis are selected and a popup opens representing the two chassis together. You cannot access each chassis individually. |
Step 4 | To display links in the cluster topology: |
The topology map clearly shows which chassis is primary and which is the backup chassis. Further details about the chassis are provided in the Device 360 view.
To identify the primary and backup devices and get more information:
