The Satellite Network Virtualization (nV) feature allows you to
configure remote routers to act as remote virtual switch interfaces. nV mode
allows the router to act as a satellite nV device, controlled using the CLI.
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
Removing a Satellite Image.
Restoring the Cisco NCS 4200 Series 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,
please contact Cisco support.
