Login Accounts
The
UI
provides three default login accounts—Administrator, User and Diagnostics. The
Administrator login provides full access to all functions. The initial login name for an Adminis-
trator account is
admin
. The Diagnostics login also has full access to all switch functions plus a
special sub-menu with a set of switching module tests. The initial login name for Diagnostics
is
diag
. The User login has read-only privileges to the switch. The initial login name for a User
account is
user
. The password for each of these default login accounts is
switch
.

Note
♦
In software release 4.3, the
user
login account with
read-only privileges is not included automatically.
♦
Note
♦
You can configure new and delete existing login
accounts with the
useradd
UI
command, that is
described in Chapter 8, “Switch Security.”
Multiple User Sessions
You can have up to four simultaneous connections to an Omni Switch/Router. One connec-
tion can be made to the console port, two can be made through Telnet, and one connection
can be made to the modem port if you are connecting to an Omni Switch/Router.

Note
♦
For software Releases 4.4 and later, more than one
login account with write privileges
can be active at the
same time.
For software Release 4.3 and earlier, only one login account with write privileges was allowed
on the switch at the same time. In this case, the first switch user who logged on as either
admin
or
diag
would be the only user with the write privilege. Subsequent users who logged
on as either
admin
or
diag
would not have the write privilege and would be unable to
perform any functions that change switch parameters. These users would also see a message
that informs them they do not have the write privilege when they log on. For example, a user
who logs on as
admin
when another user already has the write privilege will see the follow-
ing message:
You are logged in as 'admin' without the WRITE privilege.
The WRITE privilege is currently in use by another user.
However, users who log on as either
admin
or
diag
without the write privilege can “kill” the
session of the user with the write privilege and gain that privilege for themselves. This is
described in Deleting Other Sessions on page 4-35.
If you try to log on when the limit of user has been reached (e.g., you attempt a Telnet
connection when there are two users currently connected through Telnet), you will see the
following message:
Sorry, reached maximum number of sessions.
