MSCHAP is similar to CHAP but is more secure because the server stores and compares only
encrypted passwords rather than cleartext passwords as in CHAP. MSCHAP also generates a
key for data encryption by MPPE.
f. (Optional) To store the username and password in Flash memory, check the Store Username
and Password in Local Flash check box.
The ASA stores the username and password in a special location of NVRAM. If an Auto Update
Server sends a clear configure command to the ASA, and the connection is then interrupted,
the ASA can read the username and password from NVRAM and re-authenticate to the Access
Concentrator.
g. (Optional) To display the PPPoE IP Address and Route Settings dialog box where you can
choose addressing and tracking options, click IP Address and Route Settings. See the “PPPoE
IP Address and Route Settings” section on page14-10 for more information.
Step8 (Optional) In the Description field, enter a description for this interface.
The description can be up to 240 characters on a single line, without carriage returns. In the case of a
failover or state link, the description is fixed as “LAN Failover Interface,” “STATE Failover Interface,”
or “LAN/STATE Failover Interface,” for example. You cannot edit this description. The fixed description
overwrites any description you enter here if you make this interface a failover or state link.
Note (ASA 5510 and higher) For information about the Configure Hardware Properties button, see the
“Enabling the Physical Interface and Configuring Ethernet Parameters” section on page12-23.
