About the Default Server Encryption Type and Preshared Key
You need to configure the preshared key to authenticate the switch to the server.
The length of the key is restricted to 64 characters and can include any printable ASCII characters (white
spaces are not allowed). You can configure a global key to be used for all server
configurations on the switch.
You can override this global key assignment by explicitly using the
key
option when configuring and
individual server.
Enabling
By default, the feature is disabled in all switches in the Cisco MDS 9000 Family. You must
explicitly enable the feature to access the configuration and verification commands for fabric
authentication. When you disable this feature, all related configurations are automatically discarded.
To enable for a Cisco MDS switch, follow these steps:
Setting the
Server Address
If a secret key is not configured for a configured server, a warning message is issued if a global key is
not configured. If a server key is not configured, the global key (if configured) is used for that server (see
the
“Setting the Timeout Value” section on page 32-20
).
Note
You can use the dollar sign ($) and the percent sign (%) in global secret keys.
To configure the server IPv4 address and other options, follow these steps:
