Upgrading SDM Firewall iSD software 27
Release Notes for the Passport 8600 Release 3.7.6
Upgrading SDM Firewall iSD software
The SDM Firewall iSD software is pre-installed on new Firewall iSDs, so no
upgrades are required.
Alteon Firewall software reinstall options
The Alteon Firewall software image is available as an .img file, installed from an
ftp or tftp server using the boot user login with the ForgetMe password. The .img
image overwrites the current software version.
If you need to upgrade or reinstall your Firewall iSD software image, then please
refer to Firewall User’s Guide and Command Reference (217315-A) for full
instructions.
Password encryption
In the Passport 8600 Software Release 3.7.6 or higher, passwords are now stored
in encrypted format and are no longer stored in the configuration file. If a
configuration file saved prior to Release 3.7.6 is loaded, saved passwords from the
configuration file are not recognized. If the switch is booted for the first time with
the software Release 3.7.6 or higher image, the password is reset to default values
and a log is generated, indicating any changes.
Note: For .img installations, all configuration parameters, logs, etc. are
lost. Be sure to save your configuration to an ftp or tftp server using the
/cfg/ptcfg command before reinstallation, and restore the
configuration after using the
/cfg/gtcfg command.
Note: For security reasons, Nortel Networks recommends setting the
passwords to values other than the factory defaults.
