Introduction

This document describes the upgrade procedure for Catalyst 9400 Dual Supervisors to Cisco IOS XE from v16.6.1 to v16.6.2.

Prerequisites

Requirements

Cisco recommends that you have knowledge of TFTP and FTP.

Components Used

The information in this document is based on these software and hardware versions:

Hardware: C9410R
Software: cat9k_iosxe.16.06.01.SPA.bin

In this example, your current image is cat9k_iosxe.16.06.01.SPA.bin and the target image is cat9k_iosxe.16.06.02.SPA.bin. This procedure also works if you have a C9407R chassis instead of a C9410R chassis.

Note: Do not upgrade dual supervisors from Cisco IOS® XE Everest 16.6.1 to 16.6.2 at the same time. Insert one supervisor at a time while you upgrade from 16.6.1 to 16.6.2.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Automatic Boot Loader Upgrade and CPLD Upgrade

Automatic Boot Loader Upgrade

When you upgrade from the current Cisco IOS® XE release on your switch to a later or newer release for the first time, the boot loader can automatically be upgraded based on the hardware version of the switch. If the boot loader is upgraded, the supervisor automatically reloads to enable the new boot loader. If you go back to the older release after this, the boot loader is not downgraded. The updated boot loader supports all previous releases.

For subsequent Cisco IOS® XE Everest 16.x.x releases, if there is a new boot loader in that release, it can automatically be upgraded based on the hardware version of the switch when you boot up your switch with the new image for the first time.

At the time when you upgrade from Cisco IOS® XE Everest 16.6.1 to 16.6.2, the upgrade can take some time while the system resets three times due to the common and Complex Programmable Logic Device (CPLD) upgrade. The stateful switchover is supported from Cisco IOS® XE Everest 16.6.2.

Different Ways to Boot Supervisor

In the Catalyst 9400 switch, you can boot the supervisor with the use of two methods:

Install mode
Traditional method to boot the device from the .bin file

When the switch runs in install mode, the Cisco IOS® XE package (.pkg) files and provisioning file (packages.conf) are stored in the system board flash memory (flash:). When the switch is booted with the use of the .bin file, the booted Cisco IOS® XE software bundle (.bin) file is stored in the system board flash memory (flash:).

After the 16.6.2 upgrade, the procedure works regardless of which boot method was used to boot the switch on the current 16.6.1 image. However, the procedure here upgrades the supervisor engine to install mode.

Upgrade Steps for Primary Supervisor

Step 1. Remove Unwanted Packages

Note: Do not skip this step and ensure you have at least 1 GB of space in your flash to expand a new image. Clean up the old installation files in case of insufficient space.

Step 2. Copy New Image to Flash

In this example, you copy the image from the TFTP server to the supervisors bootflash:

Switch#copy tftp: bootflash:
Address or name of remote host []? 172.16.53.46
Source filename []? cat9k_iosxe.16.06.02.SPA.bin
Destination filename [cat9k_iosxe.16.06.02.SPA.bin]? 
 
Accessing tftp://172.16.53.46//cat9k_iosxe.16.06.02.SPA.bin...
Loading /cat9k_iosxe.16.06.02.SPA.bin from 10.8.0.6 (via GigabitEthernet0/0): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 601216545 bytes]
 
601216545 bytes copied in 50.649 secs (11870255 bytes/sec)

Step 3. Use the dir flash command to confirm that the image has been successfully copied to flash.

Switch#dir bootflash:*.bin
Directory of bootflash:/*.bin
 
Directory of flash:/
 
434184 -rw- 601216545 Jul 26 2017 10:18:11 -07:00 cat9k_iosxe.16.06.02.SPA.bin
11353194496 bytes total (8976625664 bytes free)

Step 3. Check the Boot Statement

Ensure that the boot statement is configured to packages.conf before you upgrade to 16.6.2 in install mode. If it is set to the .bin file, you must change it to packages.conf.:

Switch#show boot
BOOT variable = bootflash:cat9k_iosxe.16.06.01.SPA.bin;
Configuration Register is 0x102
MANUAL_BOOT variable = no
BAUD variable = 9600
ENABLE_BREAK variable does not exist
CONFIG_FILE variable does not exist


Change boot variable to point to packages.conf

Switch(config)#no boot system                        
Switch(config)#boot system bootflash:packages.conf
*Nov 14 15:12:50.043: %SYS-5-CONFIG_I: Configured from console by consol 

Please save the configuration to reflect the new boot variable.

Switch#wr mem
Building configuration...
[OK]
Switch#show boot
BOOT variable = bootflash:packages.conf;
Configuration Register is 0x102
MANUAL_BOOT variable = no         >> If manual variable is set to no, it means system is set to auto boot
BAUD variable = 9600
ENABLE_BREAK variable does not exist
CONFIG_FILE variable does not exist


You can set the system to auto boot or manual boot by setting the variables:

Changing system to auto boot

Switch(config)#no boot manual

 
Changing system to manual boot

Switch(config)#boot manual

If your switches are configured with auto boot, then the switch will automatically boot up with the new image when the switch is
reloaded. If your switches are not configured with auto boot and the switch is reloaded, you will receive a Rommon prompt 
where you must then manually boot the new image flash:packages.conf 

Switch: boot flash:packages.conf"

Step 4. Software Install Image to Flash

Use the install add file activate commit command to install the target image to flash. You can point to the source image on your TFTP server or in boot flash if you have the image copied to flash. In this example, you have copied the image to the flash already.

Switch#install add file bootflash:cat9k_iosxe.16.06.02.SPA.bin activate commit install_add_activate_commit: START Fri Nov 13 22:34:41 UTC 2017 *Nov 13 22:34:21.543: %IOSXE-5-PLATFORM: R0/0: Nov 13 22:34:21 install_engine.sh: %INSTALL-5-INSTALL_START_INFO: Started install one-shot flash:cat9k_iosxe.16.06.02.SPA.bininstall_add_activate_commit: Adding PACKAGE

Upgrade Steps for Secondary Supervisor

Remove the supervisor from slot 5, which was upgraded in the previous steps, and insert the standby supervisor in slot 6 in the chassis. The removal of the first supervisor is important because to upgrade two supervisors while both of are inserted in the chassis; this is not supported as mentioned earlier. You can repeat the same upgrade steps as documented to upgrade the newly inserted supervisor.

Step 1. Remove Unwanted Packages

Note: Do not skip this step. Ensure you have at least 1 GB of space in your flash to expand a new image. Clean up the old installation files in case of insufficient space.

Step 2. Copy New Image to Flash

In this example, you copy the image from your TFTP server to the supervisors flash.

Switch#copy tftp: bootflash:
Address or name of remote host []? 172.16.53.46
Source filename []? cat9k_iosxe.16.06.02.SPA.bin
Destination filename [cat9k_iosxe.16.06.02.SPA.bin]? 
 
Accessing tftp://172.16.53.46//cat9k_iosxe.16.06.02.SPA.bin...
Loading /cat9k_iosxe.16.06.02.SPA.bin from 10.8.0.6 (via GigabitEthernet0/0):
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 601216545 bytes]
 
601216545 bytes copied in 50.649 secs (11870255 bytes/sec)

Step 3	Use the dir flash command to confirm that the image has been successfully copied to flash.

Switch#dir bootflash:*.bin
Directory of bootflash:/*.bin
 
Directory of flash:/
 
434184 -rw- 601216545 Jul 26 2017 10:18:11 -07:00 cat9k_iosxe.16.06.02.SPA.bin
11353194496 bytes total (8976625664 bytes free)

Step 3. Check Boot Statement

Ensure the boot statement is configured to the packages.conf before you upgrade to 16.6.2 in install mode. If it is set to the .bin file, you must change it to packages.conf.:

Switch#show boot
BOOT variable = bootflash:packages.conf;
Configuration Register is 0x2
MANUAL_BOOT variable = no
BAUD variable = 9600
ENABLE_BREAK variable =
BOOTMODE variable does not exist
IPXE_TIMEOUT variable does not exist
CONFIG_FILE variable =

If your switches are configured with auto boot, then the switch automatically boots up with the new image.
If not, you can manually boot flash:packages.conf
Switch: boot flash:packages.conf

Step 4. Software Install Image to Flash

Use the install add file activate commit command to install the target image to flash. You can point to the source image on your TFTP server or in bootflash if you have the image copied to flash. In this example, you have copied the image to the flash already.

Switch#install add file bootflash:cat9k_iosxe.16.06.02.SPA.bin activate commit

Check Redundancy

The supervisor modules in the Catalyst 9400 (hardware) support redundancy. Software redundancy is supported in Cisco IOS ® XE Everest 16.6.2. In the 16.6.2 software version, the Route Processor Redundancy (RPR) feature is not supported. Use the show redundancy and show platform software iomd redundancy commands to ensure that both Stateful Switchover (SSO) formed and IOMD is ready before you complete any switchovers.

RPR Redundancy

When a standby supervisor engine runs in RPR mode, it starts up in a partially-initialized state and is synchronized with the persistent configuration of the active supervisor engine. RPR is not supported in 16.6.2.

In the event of supervisor engine switchover, traffic is disrupted because in RPR mode all physical ports restart since there is no state maintained between supervisor engines which relates to module types and statuses. Upon switchover, when the standby supervisor engine completes its initialization, it reads hardware information directly from the module and becomes the active supervisor engine.

SSO Redundancy

When a standby supervisor engine runs in SSO mode, the standby supervisor engine starts up in a fully-initialized state and synchronizes with the persistent configuration and the running configuration of the active supervisor engine. It subsequently maintains the state on the protocols listed here, and all changes in hardware and software states for features that support stateful switchover are kept in synchronization.

Consequently, it offers zero interruption to Layer 2 sessions in a redundant supervisor engine configuration.

Because the standby supervisor engine recognizes the hardware link status of every link, ports that were active before the switchover remain active, which includes the uplink ports. However, because uplink ports are physically on the supervisor engine, they can be disconnected if the supervisor engine is removed.

If the active supervisor engine fails, the standby supervisor engine becomes active. This newly active supervisor engine uses existing Layer 2 switching information to continue to forward the traffic.

IOMD is Input Output Module Driver software process. Check if IOMds are ready and have initialized Software/hardware.
