Information About Connection Methods
From the switch CLI, you can use two methods to connect to the ASASM:

Logging In, page 1-4
Virtual console connection—Using the service-module session command, you create a virtual
console connection to the ASASM, with all the benefits and limitations of an actual console
connection.
Benefits include:
–
The connection is persistent across reloads and does not time out.
–
You can stay connected through ASASM reloads and view startup messages.
–
You can access ROMMON if the ASASM cannot load the image.
–
No initial password configuration is required.
Limitations include:
–
The connection is slow (9600 baud).
–
You can only have one console connection active at a time.
–
You cannot use this command in conjunction with a terminal server where Ctrl-Shift-6, x is the
escape sequence to return to the terminal server prompt. Ctrl-Shift-6, x is also the sequence to
escape the ASASM console and return to the switch prompt. Therefore, if you try to exit the
ASASM console in this situation, you instead exit all the way to the terminal server prompt. If
you reconnect the terminal server to the switch, the ASASM console session is still active; you
can never exit to the switch prompt. You must use a direct serial connection to return the console
to the switch prompt. In this case, either change the terminal server or switch escape character
in Cisco IOS, or use the Telnet session command instead.
Note
Because of the persistence of the console connection, if you do not properly log out of
the ASASM, the connection may exist longer than intended. If someone else wants to
log in, they will need to kill the existing connection. See the
Session" section on page 1-5
Telnet connection—Using the session command, you create a Telnet connection to the ASASM.
Note
You cannot connect using this method for a new ASASM; this method requires you to
configure a Telnet login password on the ASASM (there is no default password). After you
set a password using the passwd command, you can use this method.
Benefits include:
–
You can have multiple sessions to the ASASM at the same time.
–
The Telnet session is a fast connection.
Limitations include:
–
The Telnet session is terminated when the ASASM reloads, and can time out.
–
You cannot access the ASASM until it completely loads; you cannot access ROMMON.
–
You must first set a Telnet login password; there is no default password.
