Backing up the current software images

Before performing a software upgrade, Brocade recommends backing up the following current software images in the device’s flash memory.

Syntax:

cp <original-file-name> <backup-file-name>

Upgrading the monitor and boot images

You can upgrade the management module’s monitor and boot images simultaneously. Brocade highly recommends that the interface monitor and boot images be upgraded to the same

software release version as the management module images to keep both code images synchronized on the same version. See Upgrading the interface module monitor and boot images .

To upgrade the management module monitor and boot images simultaneously, perform the following steps.

1. Place the new monitor and boot images on a TFTP server to which the BigIron RX system has

access or on a PCMCIA flash card inserted in slot 1 or 2.

2. Copy the new monitor and boot images to the BigIron RX. Enter one of the following commands

at the Privileged EXEC level of the CLI (example: BigIron RX#): Note: When

filename, such as

These filenames are found when issuing the dir command.

using copy flash flash <filename> and copy flash lp <filename> commands, you must enter correct

primary, secondary, monitor, lp-monitor-0, lp-primary-0 and lp-secondary-0.

Command syntax for upgrading monitor and boot images

on the management module

Command syntax Description

copy tftp flash <TFTP-server-ip-addr> <imagename> monitor copy-boot

copy slot1 | slot2 flash <image-name> monitor copy-boot

Copies the latest monitor and boot images from the TFTP server to flash.

Copies the latest monitor and boot images from a flash card in slot 1 or 2 to flash.

For example, to copy the management module boot and monitor image from TFTP server 10.10.12.12, enter

BigIron RX#copy tftp flash 10.10.12.12 rmb02702a.bin monitor copy-boot

Verify that the new monitor and boot images have been successfully copied to flash or slot 1 or 2

by entering one of the following commands at the Privileged EXEC level of the CLI:

• show flash

IronWare Software Release 02.7.02a for Brocade BigIron RX Series Swtches Release Notes v 1.0 Page 21 of 46

Page 22

•

dir /<path-name>/ (if the destination is slot 1 or 2)

Check for the boot image, monitor image, and the date and time at which the new images were built.

4. If you want to upgrade other software images, go to the appropriate upgrade section for

information. If you have completed upgrading the software images, you must reboot the management module to complete the upgrade process.

Unified software image upgrade

BigIron RX software release 02.6.00 and later can be upgraded using the Unified Software Image Upgrade procedure. When copying the image, you must load the lp-boot and mp-boot. You can set parameters to limit the images being copied and to direct images to be copied to the secondary image location to a later release by doing the following:

Failure to load the lp-boot and mp-boot when copying the unified image will cause the LP to become stuck in an interactive mode.

1. Copy the unified software image (rx02702a.bin) from a TFTP server to the switch.

For example, to copy the entire unified software image, the lp-boot and the mp-boot from a TFTP server at IP address 10.10.12.12, use the following command.

BigIron RX#copy tftp image 10.10.12.12 rx02702a.bin lp-boot mp-boot

Syntax: copy tftp image <TFTP-server-ip-addr> <image-name> [lp-boot | lp-sec | mp-boot | mpsec | mbridge]

The <TFTP-server-ip-addr> variable is the IP address for the TFTP server you are downloading the image from.

The <image-name> variable is the name of the unified software image you want to download to the switch.

The lp-boot parameter specifies that you want to download the new interface module boot image. The lp-sec parameter specifies that interface image be copied to the secondary location in flash.

The mbridge parameter tells the BigIron RX to copy the MBRIDGE image. It will now include two MBRIDGES; one for BigIron RX-16/8/4 (mbridge21.xsvf) and one for the BigIron RX32(mbridge32.xsvf).

The mp-boot parameter specifies that you want to download the new management module boot image.

The mp-sec parameter specifies that management image be copied to the secondary location in flash

2. Reboot the management module using the reload command.

3. If you are using SSH v2, you must clear the crypto key using the crypto key zeroize command

after you upgrade. Then, regenerate a new crypto key using the crypto key generate command.

Special instructions for using interface modules in a 32-slot chassis

The BigIron RX-32 chassis introduced with this release can use interface modules in the BigIron RX series that have older versions of the Multi-Service IronWare software installed on them. There are however a couple of issues regarding older versions of the software that might be installed on interface

IronWare Software Release 02.7.02a for Brocade BigIron RX Series Swtches Release Notes v 1.0 Page 22 of 46

Page 23

modules that you already own. They can work properly but must be installed as described in the following:

Separation of boot and monitor images

Beginning with version 02.5.00 and later of the Multi-Service IronWare software, the boot and monitor images no longer need to be upgraded with each release.

 The Boot images no longer need to be upgraded with each release and in fact will almost never need

to be changed. This eliminates one extra step in the upgrade process, thus simplifying the upgrade procedure, reducing the chance of operator error and leading to a faster upgrade process.

 The Monitor image no longer needs to be upgraded with each release. In release 02.5.00, all OS

functions have been moved out of the Monitor image into the IronWare image. This has simplified the Monitor image and it no longer needs to be upgraded every time, thus eliminating another step in the upgrade process.

 The first version of the boot and monitor image supporting this separation is 02.5.00

Upgrading the management module monitor and boot images

You can upgrade the management module monitor and boot images simultaneously. Brocade highly recommends that the interface monitor and boot images be upgraded to the same

software release version as the management module images to keep both code images synchronized on the same version. See Upgrading the interface module monitor and boot images .

To upgrade the management module monitor and boot images simultaneously, perform the following steps:

1. Place the new monitor and boot images on a TFTP server to which the BigIron RX system has

access or on a PCMCIA flash card inserted in slot 1 or 2.

2. Copy the new monitor and boot images to the BigIron RX. Enter one of the following commands

at the Privileged EXEC level of the CLI (example: BigIron RX#):

Command syntax for upgrading monitor and boot images

on the management module

Command syntax Description

copy tftp flash <TFTP-server-ip-addr> <image-name> monitor copy-boot

copy slot1 | slot2 flash <image-name> monitor copy-boot

Copies the latest monitor and boot images from the TFTP server to flash.

Copies the latest monitor and boot images from a flash card in slot 1 or 2 to flash.

For example, to copy the management module’s boot and monitor image from TFTP server

10.10.12.12, enter

3. Verify that the new monitor and boot images have been successfully copied to flash or slot 1 or 2

by entering one of the following commands at the Privileged EXEC level of the CLI:

• show flash

• dir /<path-name>/ (if the destination is slot 1 or 2)

Check for the boot image, monitor image, and the date and time at which the new images were built.

4. If you want to upgrade other software images, go to the appropriate upgrade section for

information. If you have completed upgrading the software images, you must reboot the management module to complete the upgrade process. For more information, see Rebooting the management module.

Upgrading the management module IronWare image

To upgrade the management module IronWare image (primary or secondary), you must perform the following steps:

1. Place the new IronWare image on a TFTP server to which the BigIron RX system has access or

on a PCMCIA flash card inserted in slot 1 or 2.

2. Copy the new IronWare image from the TFTP server or a flash card in slot 1 or 2 to the

management module’s code flash or a flash card in slot 1 or 2. To perform this step, enter one of the following commands at the Privileged EXEC level of the CLI:

• copy tftp flash <TFTP-server-ip-addr> <image-name> primary | secondary

• copy tftp slot1 | slot2 <TFTP-server-ip-addr> <image-name> primary | secondary

• copy slot1 | slot2 flash <image-name> primary | secondary

• copy slot1 | slot2 slot1 | slot2 <image-name> <dest-name>

For example, to copy the management module’s Ironware image from TFTP server 10.10.12.12, enter

BigIron RX#copy tftp flash 10.10.12.12 rmpr02702a.bin primary

Verify that the new IronWare image has been successfully copied to the specified destination by entering one of the following commands at the Privileged EXEC level of the CLI:

• show flash (if the destination was code flash)

• dir /<path-name>/ (if the destination was slot 1 or 2)

Check for the primary or secondary image and the date and time that it was placed in the directory.

4. If you want to upgrade other software images, go to the appropriate upgrade section for

information. If you have completed upgrading the software images, you must reboot the management module to complete the upgrade process. For more information, see Rebooting the management module.

Upgrading the interface module monitor and boot images

We recommend that you perform this upgrade procedure from a PC or terminal that is directly connected to the management module’s Console port. You can also perform this procedure via a Telnet or SSHv2 session.

To upgrade monitor and boot images simultaneously for an interface, perform the following steps:

1. Place the new monitor and boot images on a TFTP server to which the BigIron RX system has

access or on a PCMCIA flash card inserted in slot 1 or 2.

2. Copy the new monitor and boot images to the BigIron RX. Enter one of the following commands

at the Privileged EXEC level of the CLI (example: BigIron RX#):

Command syntax for upgrading the monitor and boot images

on the interface module

Command syntax Description

copy tftp lp <TFTP-server-ip-addr> <image-name>monitor all | <slot- number>

copy tftp lp <TFTP-server-ip-addr> <image-name>monitor copy-boot all | <slot-number>

Copies the latest monitor image from the TFTP server to all interface modules or to the specified interface module (slot-number).

Copies the latest monitor and boot images from the TFTP server to all interface modules or to the specified interface module (slot-number).

For example, to copy the interface module’s boot and monitor image from TFTP server

10.10.12.12, enter

BigIron RX#copy tftp lp 10.10.12.12 rlb02702a.bin monitor all

Verify that the new images were successfully copied to code flash by entering the following command at the Privileged EXEC level of the CLI:

• show flash

Check for the monitor image, boot image, and the date and time at which the new images were built.

4. If you want to upgrade other software images, go to the appropriate upgrade section for

information. If you have completed upgrading the software images, you must reboot the management module to complete the upgrade process. For more information, see Rebooting the management module.

Upgrading the IronWare image on the interface module

To upgrade the IronWare image (primary or secondary) on all interface modules or an interface module in a specified chassis slot, you must perform the following steps:

1. Place the new IronWare image on a TFTP server to which the BigIron RX system has access or

on a PCMCIA flash card inserted in slot 1 or 2.

IronWare Software Release 02.7.02a for Brocade BigIron RX Series Swtches Release Notes v 1.0 Page 25 of 46

Page 26

Copy the new IronWare image from the TFTP server or a flash card in slot 1 or 2 to all interface modules or an interface module in a specified chassis slot. To perform this step, enter one of the following commands at the Privileged EXEC level of the CLI (example: BigIron RX#):

• copy tftp lp <TFTP-server-ip-addr> <image-name> primary | secondary all

• copy tftp lp <TFTP-server-ip-addr> <image-name> primary | secondary <chassis-slot-

number>

• copy slot1 | slot2 lp <image-name> primary | secondary all

• copy slot1 | slot2 lp <image-name> primary | secondary <chassis-slot-number>

For example, to copy the interface module’s IronWare image from TFTP server 10.10.12.12, enter

BigIron RX#copy tftp lp 10.10.12.12 rlp02702a.bin primary all

NOTE: If you copy the new IronWare image to all interface modules using the all keyword, the management module makes a copy of the image (called lp-primary-0 or lp-secondary-0) and stores it in its code flash, thereby synchronizing the new IronWare image on both the interface and management modules.

If you copy the new IronWare image to a specified chassis slot, the management module does not make a copy of the image or store it. In this case, the new IronWare image on the interface module is unsynchronized or different from the IronWare image on the management module.

For more information about synchronizing the new IronWare image or retaining unsynchronized versions of the IronWare image on the interface and management modules, see Rebooting the management module.

3. Verify that the new IronWare image has been successfully copied by entering the following

command at any level of the CLI:

BigIron RX# show flash

Check for the IronWare image and the date and time at which the image was built.

If you want to upgrade other software images, go to the appropriate upgrade section for information. If you have completed upgrading the software images, you must reboot the management module to complete the upgrade process. For more information, see Rebooting the management module.

Upgrading MBRIDGE FPGA on the management module

BigIron RX management modules contain an upgradable FPGA images called MBRIDGE and SBRIDGE. The MBRIDGE and SBRIDGE image installed must be compatible with the software version you are running on the BigIron RX.

To upgrade the MBRIDGE FPGA image on a BigIron RX management module, you must perform the following general steps:

1. Determine the versions of the images currently installed on the BigIron RX management module

using the show version command.

1. Place the new MBRIDGE FPGA image on a TFTP server to which the BigIron RX system has

access or on a PCMCIA flash card inserted in slot 1 or 2.

2. Copy the MBRIDGE FPGA image from the TFTP server or a flash card in slot 1 or 2 to all

management modules or a management module in a specified chassis slot. To perform this step, enter one of the following commands at the Privileged EXEC level of the CLI (example: BigIron RX#):

• copy tftp mbridge <TFTP-server-ip-addr> <image-name> MBRIDGE

• copy slot1 | slot2 mbridge <image-name> MBRIDGE

3. After the MBRIDGE upgrade is complete, the management module must be reloaded.

4. Verify that the MBRIDGE image(s) have been successfully copied to the specified interface

module(s) by entering the following command at any level of the CLI:

• show version

Check for the MBRIDGE image version numbers in the output. See MBRIDGE.

Rebooting the management module

After upgrading one or more software images on the management or interface module, you must reboot the management module. After the management module reboots, it in turn reboots the interface modules.

To reboot the management module, enter one of the following commands:

 reload (this command boots from the default boot source, which is the primary code flash)  boot system flash primary | secondary

During the management module reboot, the following synchronization events occur:  If you have a standby management module, the active management module compares the standby

module’s monitor, primary, and secondary images to its own. If you have updated these images on the active module, the active module automatically synchronizes the standby module’s images with its own.

 If you copied the primary and/or secondary IronWare image to all interface modules using the copy

command with the all keyword, the management module made a copy of the image and stored it in its code flash under the names lp-primary-0 or lp-secondary-0. By default, the BigIron RX system checks the interface modules’ IronWare images, which reside in the code flash of the interface modules and the management module to make sure they are the same in both locations. (These IronWare images are stored on the management module only and are not run by the management or interface modules.) If the IronWare images on the interface and management modules are different, the system prompts you to do the following:

 If you want to update the IronWare images in the interface module’s code flash with the

images in the management module’s code flash, enter the lp cont-boot sync <slot-number> command at the Privileged EXEC prompt.

 If you want to retain the IronWare images in the interface module’s code flash, enter the lp

cont-boot no-sync <slot-number> command at the Privileged EXEC prompt.

After the management module finishes booting, do the following:  Enter the show module command at any CLI level, and verify that the status of all interface modules

is CARD_STATE_UP.

 Enter the show version command at any CLI level, and verify that all management and interface

modules are running the new software image version.

If you find that an interface module is in a waiting state or is running an older software image, then you may have forgotten to enter the lp cont-boot sync <slot-number> command at the Privileged EXEC prompt.

You also need to upgrade the MBRIDGE FPGA on the management module.

Regenerating SSH v2 crypto key

If you are using SSH v2, you must clear the crypto key using the crypto key zeroize command after you upgrade from any release 02.2.01 and later. Then, regenerate a new crypto key using the crypto key generate command.

Hitless Layer 2 OS upgrade

Hitless O/S upgrades are supported for Layer 2 switching and Layer 2 protocols only. See the Upgrading Software Images and Configuration Files chapter in the BigIron RX Installation Guide for additional information. The hitless O/S Layer 2 upgrade allows for upgrading the software in a system between two releases of the O/S, which support this functionality and have compatible data structures. A hitless O/S Layer 2 downgrade may also be supported if the current and target code releases have compatible data structures. From time to time, it may become necessary when enhancing the software or adding new features to change or add data structures making releases incompatible. In these cases, an upgrade or downgrade will not be hitless, and will fall back to using the regular Brocade upgrade process – relying on fast reboot.

When performing a hitless O/S Layer 2 upgrade or downgrade, use the following guidance:

 Hitless O/S Layer 2 upgrade or downgrade is not supported in 2.3.00 or earlier.  Hitless O/S Layer 2 upgrade support is in 2.3.00a and higher patch releases (unless indicated

otherwise in the target software’s release notes).

 Hitless upgrade maintains forwarding states and control plane functionality of the active software

from which you are upgrading (i.e. 2.3.00a to 2.3.00d would only maintain the functionality supported by 2.3.00a).

 Hitless downgrades are recommended only between compatible patch releases of a feature release

such as between 2.3.00b to 2.3.00a (to ensure the higher release has no conflicting functional enhancements that do not exist in the lower release).

 Due to the PBIF change introduced in patch release version 02.3.00e and version 02.3.00f, users

cannot perform hitless upgrades from earlier 02.3.00 versions or 02.3.00g or higher versions. For information on Hitless Upgrades refer to the “Hitless OS Upgrade” section in the BigIron RX Installation Guide.

 Due to Internal changes introduced in patch release version 02.4.00d ,hitless upgrade is not supported

onto 02.4.00b and hitless downgrade is not supported from 02.4.00d.

 The Hitless upgrade feature is not supported on release 02.5.00b to 02.5.00c for the BigIron RX-32

only. It is supported on all other BigIron RX devices.

Using this feature, you can upgrade the Multi-Service IronWare software without a loss of service or disruption in the following supported functions and protocols:

 All ports and links remain operational  TOS-based QoS  Layer-2 Switching  Layer-2 Protocols:

 MRP  STP  VSRP  RSTP  MSTP

Page 31

Considerations when using the feature

Consider the following when using this feature:

 You must have both active and standby management modules installed to use this feature.  To avoid any disruptions of Layer-3 traffic to OSPF or BGP routes, the switch must be configured

with OSPF Graceful Restart and BGP Graceful Restart features. In addition, the device’s OSFP neighbors must have OSPF Graceful Restart Helper enabled.

The total time it takes for the hitless upgrade process to finish varies between approximately 1 and 10 minutes. This depends on the size of the MAC table, the number of OSPF and BGP neighbors and the size of the routing table. Switch configuration is unavailable during the entire hitless upgrade process. The message "---SW Upgrade In Progress - Please Wait---" is printed at the console when configuration is attempted. Operational command of the switch is allowed during the upgrade process.

 The active management module changes from the initial active management module to the standby

management module during the hitless upgrade process. This makes it necessary to have a connection to the console interface on both management modules.

 Upon being reset, the management and interface module CPUs are unable to send and receive any

packets. Once the management and interface modules are up and running, their CPUs are able to send and receive packets, even before the hitless upgrade process is complete.

 Switch configuration is not allowed to be changed during the entire hitless upgrade process.  System-max parameter changes or other configuration changes that require a system reload such as

"cam-mode" and cam-profile" changes do not take effect upon hitless upgrade.

 FPGA images cannot be upgraded using the hitless upgrade process.  This feature cannot be used to downgrade an image to an older major version than the version that the

device is currently running.

 If there are protocol dependencies between neighboring nodes, it’s recommended that only each node

is upgraded: one node at a time.

 After hitless upgrade, the BigIron RX switch will still have the same running configuration as it does

before the upgrade. A configuration that is not saved before hitless reload is not removed and the existing startup configuration does not take effect. This behavior is the same as displayed by the management module switchover feature.

The Hitless OS Layer 2 software process

Hitless OS Layer 2 upgrade of Multi-Service IronWare software is performed in the following steps.  Version 02.3.00 or later of the Multi-Service IronWare software is installed in flash memory to the

primary and secondary image on the active and standby management modules and interface modules.

 The hitless-reload command is executed on the active management module.  The hitless upgrade process is begun on the active management module which initiates the upgrade

process on the standby management module.

 The standby management module is reset.  The active management module is reset and the standby management module assumes control as the

active module.

IronWare Software Release 02.7.02a for Brocade BigIron RX Series Swtches Release Notes v 1.0 Page 31 of 46

Page 32

 Active console control is lost to the previously active management module as it becomes the standby

management module.

 The active management module initiates the upgrade process on all interface modules.  The switch is now operating on the new Multi-Service IronWare software. The management module

that was initially configured as the standby management module is now the active management module and the management module that was initially configured as the active management module is now the standby.

Management module (MP) and Interface Module (LP) Hitless Upgrade Process provides a detailed diagram of the Hitless reload process.

Figure 1 Management module (MP) and Interface Module (LP) Hitless Upgrade Process

Performing a Hitless Layer 2 OS software upgrade

To perform a hitless Layer 2 OS software upgrade, you must perform the following tasks:  Copy version 02.3.00 or later of the Multi-Service IronWare software to the primary and secondary

image on both the active and standby management modules and interface modules.

 Setup a console connection to both the active and standby management modules. These connections

can be through a telnet, SSH, or serial console session.

 Type the hitless-reload command at the console of the active management module.

Loading the Multi-Service IronWare software onto the switch

IronWare Software Release 02.7.02a for Brocade BigIron RX Series Swtches Release Notes v 1.0 Page 32 of 46

Page 33

Hitless Layer 2 OS upgrade loads from the primary and secondary images on the Management modules. The first step in performing a hitless Layer 2 OS upgrade is to copy the version 02.3.00 or later images into the flash memory of the active and standby management modules.

For instructions for copying these files, see Upgrading the management module monitor and boot images and Upgrading the management module IronWare image.

Setting up consoles

Hitless Layer 2 OS upgrade is executed at the active management module. During the process of upgrading the image, control of the switch is shifted to the standby management module. For this reason, you need to have management sessions enabled on both the active and the standby management modules. When the reload is complete, the management module that was in the standby condition at the beginning will be in the active state. If you want the original management module to be active, you must manually fail-over control to it.

Executing the Hitless upgrade command

To begin the process of a hitless upgrade, use the following command:

BigIron RX(config)# hitless-reload mp primary lp primary

Syntax: hitless-reload mp [primary | secondary ] lp [primary | secondary] The mp parameter specifies that the management module will be reloaded with either the primary or

secondary image as directed. The lp parameter specifies that the management module will be reloaded with either the primary or

secondary image as directed.

Verify the new software image

Enter the show version command at any CLI level, and verify that all management and interface modules are running the new software image version.

Documentation Update

The system monitoring service (SYSMON) feature was introduced in the 02.6.00c patch release. This feature monitors the hardware in the system to detect, report, and in some cases isolate and recover hardware errors in the system. When an error or event occurs, SYSMON generates Syslog messages, which must be reported to Brocade Technical Support.

In the 02.7.02a patch release, the following enhancements were added:

1. A read and write test was added to detect failed Switch Fabric Module (SFM) FE failures. A Syslog

message is generated to indicate a SFM FE failure.

2. The performance of ingress DRAM CRC detection was improved. This detection now has two

methods to detect errors; an interrupt routine is used to detect these errors quickly and will trigger a shutdown of the failed TM. Long term polling has been added to detect low rate CRC errors which will be reported with a Syslog message.

3. TM blocked (stuck) buffers can now be detect and recovered from egress. This process generates a

Syslog message.

Note: As a result of the extended monitoring enhancements, any marginal hardware may be reported as defective.

Furthermore, The default behavior for TM register monitor action has been changed. The shutdown action is now enabled by default. Enter no sysmon tm reg shutdown command to disable this action.

The following table presents the examples of Syslog message generated by SYSMON for the events that trigger them.
