Enabling Network Virtualization Satellite Mode on the Router
This document describes how to enable Network Virtualization Satellite Mode on the Router and contains the following sections:
The following limitations apply when enabling nV satellite mode:
An in-service software upgrade (ISSU) is not supported while the router is acting as an nV satellite device.
RSP redundancy is not supported while the router is acting as a satellite nV device.
Online Insertion and Removal (OIR) of interface modules (IMs) is not supported when the router is operating in nV satellite mode.
Supported connections to the satellite host include
Gigabit Ethernet interfaces
Ethernet transported over optical interfaces
10 Gigabit Ethernet interfaces (slots 1 and 2 only)
Other connection types are not supported.
Local switching on the satellite device is not supported. The packets are always sent to the host for layer 2 and layer 3 switching.
Network clocking is not supported when the router is operating in nV satellite mode.
Reverting from a satellite mode image to the base image requires that you download the original image using TFTP; an inband download is not supported. For more information, see .
Installing a Satellite Image on the Router
Follow these steps to install a satellite nV image on the Router:
- Download a Cisco ASR 903 Router satellite nV image from Cisco.com and copy the image to a TFTP server.
- Create a console connection to the management port of the Router. For more information about creating a console connection, see .
- Copy nV compatible binary image to flash or bootflash.
- Set the configuration register to 0x2042.
- Erase the existing configuration.
- Specify the boot image.
- Save the configuration.
- Reload the router

Erase the existing configuration.
Specify the boot image.
Save the configuration.
Reload the router
The system boots in nV mode and is detectable by the nV host.
You can use the show nv satellite status command to verify the image version.
Removing a Satellite Image from the Router
Restoring the router to a normal IOS XE image requires that you load an image in ROMmon mode using trivial file transfer protocol (TFTP). For instructions on how to remove a satellite image from the router, please contact Cisco support.
Configuring Satellite Mode Sequence
When booting to a satellite nV image, the router
enables Ethernet ports in IEEE mode.
enables inter-chassis links (IC links).
uses Satellite Discovery and Control (SDAC) to establish a connection to the host nV device.
establishes a control path between the host nV device and the router.
Upgrading the Satellite Image
After you connect the satellite to the host, the host verifies the satellite software version. If there is a version mismatch, the host displays a syslog notification indicating that the satellite device requires an image upgrade. To upgrade the image using the host satellite device, see Configuring the Satellite Network Virtualization (nV) System on the Cisco ASR 9000 Series Router.
Use the show nv satellite status command to verify the image version.
