If the router is operating in security mode, the manager must also be logged in to a user
account with SECURITY OFFICER privilege in order to execute any of the commands
listed in Table 1-3 on page 1-16.
Logging In and Logging Out
A user will automatically be prompted to enter a login name and password
when attempting to access the router via Telnet or a terminal connected to an
asynchronous port set to SECURE mode, or when attempting to access a dialup
service via an asynchronous modem connected to an asynchronous port.
There are other occasions when a user may wish to login manually. A user on a
terminal connected to an asynchronous port that is not in SECURE mode may
wish to login in order to use facilities that are only available to logged in users,
such as the TELNET command on page 11-24 of Chapter 11, Terminal Server. A
user who is already logged in may wish to temporarily login as another user in
order to acquire different rights, such as MANAGER privilege.
To log in to the router manually, use one of the commands:
LOGIN
LOGON
LOGI
which are synonyms. To log out of a session, use one of the commands:
LOGOFF
LOGOUT
LO
which are synonyms.
If a user Telnets to the router but does not attempt to login within one minute, the router
automatically times out the session and terminates the Telnet connection.
