Password and SNMP community string encryption

In the Ethernet Routing Switch 8300 Software Release 2.2, passwords and
community strings are stored in encrypted format and are not stored in the
configuration file. If the switch is booted for the first time with the Software
Release 2.2 image, the community strings are reset to default values and a
log is generated indicating any changes.

CAUTION

For security reasons, Nortel recommends that you set the
community strings to values other than the factory defaults.

Web-server passwords and SNMP community strings are also encrypted.

•

Web Server password

The web-server passwords authenticate the user who is accessing the
switch using the web interface. The passwords are encrypted using the
blowfish algorithm and are stored in a hidden file. They are not visible
on the switch through any

show

command and are not stored in the

config file.

•

SNMP community strings

SNMP community strings are used when the user logs in to the switch
over SNMP, for example, using Device Manager. These strings are
encrypted using the blowfish algorithm and are stored in a hidden file.
They are not displayed on the switch and are not stored in the config file.

Modifying and resetting passwords

For recovery (passwords lost), you have to reset the switch and apply the
following command in Boot Monitor mode:

monitor#reset-passwd

For other issues related to passwords, contact Nortel customer support.

All passwords are case sensitive.
