C H A P T E R 2Upgrading or Downgrading the Cisco Nexus 3500Series NX-OS Software

This chapter describes how to upgrade or downgrade the Cisco NX-OS software. It contains the followingsections:

• About the Software Image, on page 3• Prerequisites for Upgrading the Cisco NX-OS Software, on page 3• Prerequisites for Downgrading the Cisco NX-OS Software, on page 4• Cisco NX-OS Software Upgrade Guidelines, on page 4• Cisco NX-OS Software Downgrade Guidelines, on page 5• Booting the Switch from the USB, on page 5• Upgrading the Cisco NX-OS Software, on page 6• Downgrading to an Earlier Software Release, on page 10

About the Software ImageEach device is shipped with the Cisco NX-OS software. The Cisco NX-OS software consists of two NXOSsoftware images, kickstart image and systems image (for example: n3500-uk9-kickstart.6.0.2.A6.7.bin andn3500-uk9.6.0.2.A6.7.bin). Only these images are required to load the Cisco NX-OS operating system. Theseimages run on all Cisco Nexus 3500 Series switches.

Another type of binary file is the software maintenance upgrade (SMU) package file. SMUs contain fixes forspecific defects. They are created to respond to immediate issues and do not include new features. SMUpackage files are available for download from Cisco.com and generally include the ID number of the resolveddefect in the filename. For more information on SMUs, see the Cisco Nexus 3500 Series NX-OS SystemManagement Configuration Guide.

Note

Prerequisites for Upgrading the Cisco NX-OS SoftwareUpgrading the Cisco NX-OS software has the following prerequisites:


• Ensure that everyone who has access to the device or the network is not configuring the device or thenetwork during this time. You cannot configure a device during an upgrade. Use the show configurationsession summary command to verify that you have no active configuration sessions.

• Save, commit, or discard any active configuration sessions before upgrading or downgrading the CiscoNX-OS software image on your device. On a device with dual supervisors, the active supervisor modulecannot switch over to the standby supervisor module during the Cisco NX-OS software upgrade if youhave an active configuration session.

• Ensure that the device has a route to the remote server. The device and the remote server must be in thesame subnetwork if you do not have a router to route traffic between subnets. To verify connectivity tothe remote server, use the ping command.switch# ping 172.18.217.1 vrf managementPING 172.18.217.1 (172.18.217.1): 56 data bytes64 bytes from 172.18.217.1: icmp_seq=0 ttl=239 time=106.647 ms64 bytes from 172.18.217.1: icmp_seq=1 ttl=239 time=76.807 ms64 bytes from 172.18.217.1: icmp_seq=2 ttl=239 time=76.593 ms64 bytes from 172.18.217.1: icmp_seq=3 ttl=239 time=81.679 ms64 bytes from 172.18.217.1: icmp_seq=4 ttl=239 time=76.5 ms

For more information on configuration sessions, see theCisco Nexus 3500 Series NX-OS SystemManagementConfiguration Guide.

Prerequisites for Downgrading the Cisco NX-OS SoftwareDowngrading the Cisco NX-OS software has the following prerequisites:

• Verify the compatibility of the software using the show incompatibility system bootflash:filenamecommand. If an incompatibility exists, disable any features that are incompatible with the downgradeimage before downgrading the software.

Cisco NX-OS Software Upgrade Guidelines

The Cisco Nexus 3500 Series NX-OS Release Notes contain specific upgrade guidelines for each release. Seethe Release Notes for the target upgrade release before starting the upgrade.

Note

Before attempting to upgrade to any software image, follow these guidelines:

• Schedule the upgrade when your network is stable and steady.

• Avoid any power interruption, which could corrupt the software image, during the installation procedure.

• The supervisor module must have connection on the console ports to maintain connectivity whenswitchovers occur during a software upgrade. See the Hardware Installation Guide for your specificchassis.


Upgrading or Downgrading the Cisco Nexus 3500 Series NX-OS SoftwarePrerequisites for Downgrading the Cisco NX-OS Software

• An upgrade to Cisco NX-OS Release 7.0(3)I7(2) is supported only from Cisco NX-OS Release6.0(2)A8(7b) or higher releases.

You must compact the Cisco NX-OS Release 7.0(3)I7(2) image before youupgrade from Cisco NX-OS Release 6.0(2)A8(x) to Cisco NX-OS Release7.0(3)I7(2). The compaction can be done only during the scp file copy process.

Note

• An upgrade to the following Cisco NX-OS releases is not supported:

• Cisco NX-OS Release 7.0(3)I2(x)





• Cisco NX-OS Release 7.0(3)I7(1)

• An upgrade from Cisco NX-OS Release 6.x to 7.x is disruptive for Cisco Nexus 3500 platform switchesin a vPC environment when the STP global port type is configured as network or edge. To work aroundthis issue, disable the spanning-tree port type {network | edge} default command, perform the upgrade,and then re-enable this command on both switches in the vPC.

Cisco NX-OS Software Downgrade GuidelinesBefore attempting to downgrade to an earlier software release, follow these guidelines:

• The supervisor module must have connection on the console ports to maintain connectivity whenswitchovers occur during a software downgrade. See the Hardware Installation Guide for your specificchassis.

• Cisco NX-OS automatically installs and enables the guest shell by default. However, if the device isreloaded with a Cisco NX-OS image that does not provide guest shell support, the existing guest shellis automatically removed and a%VMAN-2-INVALID_PACKAGEmessage is issued. As a best practice,remove the guest shell with the guestshell destroy command before downgrading to an earlier CiscoNX-OS image.

Booting the Switch from the USBStarting from Release Rel 6.0(2)A8(4), you can optionally choose to boot the switch from an external flashmemory drive at the loader prompt. The supported BIOS version for N3K-C3548P-10GX is 2.0.8 and forN3K-C3548P-10G is 1.0.11. Following are the various options for loading the image from an external flashmemory drive:

• You can load the kickstart image from USB1 when either the USB1 slot is occupied or when both theUSB slots are occupied.

• You can load the kickstart image from USB2 only when the USB2 slot is occupied.Loader> boot usb2: <kickstart image>

• You can load the kickstart image from USB2 when both the USB slots are occupied.Loader> boot usb2: <kickstart image>

• You can load the kickstart image and the system image from USB1 when only the USB1 slot is occupiedor when both the USB slots are occupied.Loader> boot usb1: <kickstart image> usb1: <system image>

• You can load the kickstart image and the system image fromUSB2 when only the USB2 slot is occupied.Loader> boot usb2: <kickstart image> usb2:<system image>

Upgrading the Cisco NX-OS Software

If an error message appears during the upgrade, the upgrade will fail because of the reason indicated.Note

Procedure

Step 1 Read the release notes for the software image file for any exceptions to this upgrade procedure. See theCisco Nexus 3500 Series NX-OS Release Notes.

Step 2 Log in to the device on the console port connection.Step 3 Ensure that the required space is available for the image files to be copied.

We recommend that you have the image files for at least one previous release of the Cisco NX-OSsoftware on the device to use if the new image files do not load successfully.

Note

Step 4 If you need more space on the device, delete unnecessary files to make space available.switch# delete bootflash:n3500-uk9-kickstart.6.0.2.A6.7.bin
