Accessing the Switch
ExtremeWare XOS 11.3 Concepts Guide

NOTE
The information that you use to configure the failsafe account cannot be recovered by Extreme Networks. Technical
support cannot retrieve passwords or account names for this account. Protect this information carefully.
To access your switch using the failsafe account, you must connect to the serial port of the switch. You
cannot access the failsafe account through any other port.
At the switch login prompt, carefully enter the failsafe account name. If you enter an erroneous account
name, you cannot re-enter the correct name.
Once you have entered the failsafe account name, you are prompted to enter the password. You will
have three tries to enter the password correctly.
Once you have successfully logged in to the failsafe account, you see the following prompt:
failsafe>
From here, you have the following four command choices:
●
Login—Use this command to access the switch CLI. You will have full administrator capabilities.
●
Reboot—Use this command to reboot the current MSM (MSM on modular switches only).
●
Help—Use this command to display a short help text.
●
Exit—Use this command to exit the failsafe account and return to the login prompt.
Typically, you use the
Login
command to correct the problem that initially required you to use the
failsafe account.
Managing Passwords
When you first access the switch you, have a default account. You configure a password for your
default account. As you create other accounts (see
“Creating a Management Account” on page 49 ), you
configure passwords for those accounts.
Beginning with ExtremeWare XOS version 11.2, the software allows you to apply additional security to
the passwords. You can enforce a specific format and minimum length for the password. Additionally,
you can age out the password, prevent a user from employing a previously used password, and lock
users out of the account after three consecutive failed login attempts.
This section discusses the following topics:

Applying a Password to the Default Account
Default accounts do not have passwords assigned to them. Passwords can have a minimum of 0
character and can have a maximum of 32 characters. (If you specify the format of passwords using the
configure account password-policy char-validation
command, the minimum is 8 characters.)
