Step 3 If the software image files are not present, log in to Cisco.com to access the links provided in this document.

To log in to Cisco.com, go to the URL http://www.cisco.com/ and click Log In at the top of the page. Enter your Cisco username and password. You can obtain the software image files from the Cisco.com software download center at the following URL: http://www.cisco.com/public/sw-center/index.shtml

.

Note If you need more space on the active or standby supervisor module bootflash:, use the delete command to remove unnecessary files.

switch# copy scp://[email protected]//downloads/n7000-s1-kickstart.4.2.1.bin

bootflash:n7000-s1-kickstart.4.0.1a.bin

switch# copy scp://[email protected]//downloads/n7000-s1-dk9.4.2.1.bin

bootflash:n7000-s1-dk9.4.0.1a.bin

Step 4 Determine if you need to disable any features not supported by the older release using the show incompatibility

system image-filename command.

switch# show incompatibility system bootflash:n7000-s1-dk9.4.2.1.bin

The following configurations on active are incompatible with the system image

1) Service : eth_port_channel , Capability : CAP_FEATURE_AUTO_CREATED_PORT_CHANNEL

Description : active mode port channels, auto create enabled ports or auto created port-channels are present

Capability requirement : STRICT

Disable command : 1.Convert Active mode port channels to On mode port channels

(no channel mode active).

2.Disable autocreate on interfaces (no channel-group auto).

3.Convert autocreated port channels to be persistent (port-channel 1 persistent).

Step 5 Disable any features that are incompatible with the downgrade system image.

Step 6 Save the running configuration to the startup configuration.

switch# copy running-config startup-config vdc-all

Step 7 Downgrade the Cisco NX-OS software.

switch# install all kickstart n7000-s1-kickstart.4.2.1.bin system n7000-s1-dk9.4.2.1.bin

Note The output displayed is similar to the output you see when you install software using the install all command.

Performing a Traditional Upgrade or Downgrade (Chassis

Reload)

This procedure is recommended for these specific scenarios:

• In lab environments where continuous uptime is not a requirement

• In production environments in the unlikely event that an upgrade needs to be downgraded in a timely manner

• In situations where ISSU or ISSD is not supported for the respective images

Cisco Nexus 7000 Series NX-OS Software Upgrade and Downgrade Guide

Before You Begin

Save and back up all configurations before reloading the system to load the new software.

Power down unsupported line cards.

Procedure

Step 1 Configure the boot variable for the Cisco NX-OS software kickstart image.

switch# boot kickstart bootflash:n7000-s1-kickstart.6.0.1.bin

Step 2 Configure the boot variable for the Cisco NX-OS software system image.

switch# boot system bootflash:n7000-s1-dk9.6.0.1.bin

Step 3 Save the running configuration to the startup configuration.

switch# copy running-config startup-config vdc-all

Step 4 Verify that the "Current Boot Variables" and the "Boot Variables on next reload" match the expected image.

switch# show boot

Current Boot Variables: sup-1 kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin

system variable = bootflash:/n7000-s1-dk9.6.0.1.bin

sup-2 kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin

system variable = bootflash:/n7000-s1-dk9.6.0.1.bin

No module boot variable set

Boot Variables on next reload: sup-1 kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin

system variable = bootflash:/n7000-s1-dk9.6.0.1.bin

sup-2 kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin

system variable = bootflash:/n7000-s1-dk9.6.0.1.bin

No module boot variable set

Step 5 Verify that the image location and the image name match the above boot statements. In redundant supervisor chassis, the images auto-synchronize from active to standby once the boot statements are set.

switch# show boot auto-copy list switch# dir bootflash://sup-active/

n7000-s1-kickstart.6.0.1.bin

Step 6 After you verify the image location and statements, reload the Cisco NX-OS device.

switch# reload
