STEP 5 Enter the parameters:
• Authentication Key ID—The key number. When you define an SNTP server
on the system, you specify which key it uses for authentication.
• Authentication Key—The value of the key. The value is the cryptographic
key that is used to encrypt and decrypt SNTP messages to and from the
server.
• Trusted Key—Indicates whether this key is a trusted key. Only trusted keys
are available for use. At least one trusted key must be configured to enable
the SNTP authentication service.
Keys are used with unicast SNTP servers only. A key is used to authenticate
an SNTP server only when the key is enabled as trusted. A keys that is
configured on the switch but specified as untrusted will not be used. An
administrator can add an untrusted key to have it available for use at another
time.
STEP 6 Click Apply and then click Close. Your changes are saved to the Running
Configuration.
