operating mode when a
valid image cannot be
loaded.
•
Access the fall-back
procedure for loading an
image when the device
lacks a valid image and
cannot be booted.
• Perform password

Diagnostic The router boots or
enters diagnostic mode
in the following
scenarios. When a
Cisco IOS XE process
or processes fail, in
most scenarios the
router will reload.
• A user-configured
access policy was
configured using
the transport-map
command, which
directed the user
into diagnostic
mode.
•
The router was
accessed using an
RP auxiliary port.
• A break signal
(Ctrl-C,
Ctrl-Shift-6, or the
send break
command) was
entered, and the
router was
configured to enter
diagnostic mode
when the break
signal was received.
Router(diag)#
If a Cisco IOS XE
process failure is the
reason for entering
diagnostic mode, the
failure must be resolved
and the router must be
rebooted to exit
diagnostic mode.
If the router is in
diagnostic mode
because of a
transport-map
configuration, access
the router through
another port or use a
method that is
configured to connect to
the Cisco IOS XE CLI.
If the RP auxiliary port
was used to access the
router, use another port
for access. Accessing
the router through the
auxiliary port is not
useful for customer
purposes.
•
Inspect various states on
the router, including the
Cisco IOS XE state.
• Replace or roll back the
configuration.
•
Provide methods of
restarting the
Cisco IOS XE software or
other processes.
• Reboot hardware, such as
the entire router, an RP, an
ESP, a SIP, a SPA, or other
hardware components.
•
Transfer files into or off
of the router using remote
access methods such as
FTP, TFTP, and SCP.
