Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide
OL-16506-17
Chapter 5 Software Upgrade Processes Supported by Cisco ASR 1000 Series Routers
Upgrade Process with Service Impact for Nonredundant Platforms
DETAILED STEPS
Command or Action Purpose
Step 1
show version
show version installed
dir
filesystem:<directory>
show platform
show redundancy-states
Example:
Router# show version
Router# show version r0 installed
Router# dir bootflash:
Router# show platform
Router# show redundancy-states
(Optional) Use the following commands to confirm the
current router configuration, as follows:
• show version and show version active-rp
installed—Verify the running version of the Cisco
IOS XE software on the router, and which file was
used to boot the router, and where that file is stored.
• dir—Confirm that the files that were used to boot
the router are located in the directory.
• show platform—Confirm the current status of the
active and standby RPs.
• show redundancy states—Confirm the operational
and configured redundancy states.
Step 2
redundancy
mode sso
Example:
Router(config)# redundancy
Router(config-red)# mode sso
Configure SSO if it is not already configured.
Note Save the configuration after making this
configuration step.
Step 3
mkdir URL-to-directory-name
Example:
Router# mkdir 221subs
Create a directory to store the consolidated package and
subpackages.
This directory must be created in most cases because the
consolidated packages and subpackages have to be
separated from the subpackages that booted the router at
this step of the procedure.
Step 4
ip tftp source-interface gigabitethernet port
Example:
Router(config)# ip tftp source-interface
gigabitethernet 0
Specifies the Gigabit Ethernet TFTP source-interface to
be configured:
slot/port—Specifies the location of the TFTP
source-interface.
Note To copy a file using TFTP through the
Management Ethernet interface, the ip tftp
source-interface GigabitEthernet 0 command
must be entered before entering the copy tftp
command.
Step 5
copy tftp: URL-to-target-location
Example:
Router# copy tftp: 221subs
Copy the consolidated package file into the directory
created in Step 3.
The consolidated package in this step should not be
copied into the same directory where the subpackages
that are currently running your router are stored (the
directory containing the packages.conf provisioning file
from which the router was booted).
Tip It is recommended that you copy the package
onto a usb: or harddisk: file system for space
considerations when performing this step of the
procedure.
