This chapter contains the upgrade and downgrade considerations, and the major differences between

FastIron 07.4.00 and 08.0.xx releases. For information on devices and FastIron software versions that

can be upgraded to FastIron 08.0.xx, see the release notes.

Upgrade and downgrade considerations

The following sections covers the details that should be considered before upgrading to FastIron

08.0.xx or downgrading to previous releases from FastIron 08.0.xx.

General considerations

General

• The erase startup-config command will erase all the startup configuration files (startup-config.txt

and also the backup files).

• FSX device with FastIron 08.0.xx, ICX 6430, and ICX 6450 devices support only one configured

system boot preference.

• In an FSX device, a mix of the SX Series 0-Port Third Generation XL management module and the

SX Series 2-Port 10GE Third Generation XL management module is not supported.

• On an FSX device with the SX Series 0-Port Third Generation XL management module, a hitless

upgrade from FastIron 08.0.00a or 08.0.01 to 08.0.10 is not supported.

• For ICX 6430 devices, the system-max mac-filter-sys parameter value has changed from 512 to

508 in FastIron 08.0.xx. If the current value of system-max mac-filter-sys is more than 508, you

should change this value to 508 before upgrading. Otherwise, during upgrade, its value will be set

to the default value of 64.

• To use 07.x.xx configuration on a device upgraded to 08.0.xx image, replacing the running

configuration with 07.x.xx configuration is not supported. You will be required to copy the 07.x.xx

configuration onto the startup configuration file and reload the device.

Deprecated or removed features and commands

• SNTP is no longer supported. NTPv4 replaces SNTP.

• Port Speed Down-Shift feature is deprecated in FastIron 08.0.xx. The link-config gig copper

autoneg-control down-shift ethernet command is deprecated.

• The show cpu-utilization command replaces the show process cpu command.

Flash memory capacity
