Command History
Usage Guidelines By default, the Cisco MDS 9000 Family switch accepts an iSCSI initiator with either no authentication
or CHAP authentication. If CHAP authentication is always required, use the iscsi authentication chap
command. If no authentication is always required, use the iscsi authentication none command.
Use the chap-none option to override the global configuration which might have been configured to
allow only one option—either CHAP or none—not both.
Note This command is not supported on the Cisco MDS 9124 switch, the Cisco Fabric Switch for HP c-Class
BladeSystem, and the Cisco Fabric Switch for IBM BladeCenter.
Examples The following example configures CHAP only for ISCSI authentication.
switch# config terminal
chap-none Configure either the CHAP or no authentication.
chap Configures the Challenge Handshake Authentication Protocol (CHAP)
authentication method.
none Specifies that no authentication is required for the selected interface
username username Assigns CHAP username to be used when switch is authenticated.
password Configures the password for the username.
0 Specifies that the password is a cleartext CHAP password.
7 Specifies that the password is an encrypted CHAP password.
password Specifies a password for the username.
Release Modification
