To define SNTP authentication:
STEP 1 Click Administration > Time Settings > SNTP Authentication. The SNTP
Authentication page opens.
STEP 2 Select SNTP Authentication to require authentication of an SNTP session
between the switch and an SNTP server.
STEP 3 Click Apply to update the switch.
STEP 4 Click Add. The Add SNTP Authentication page opens.
STEP 5 Enter the following parameters:
• Authentication Key ID—Enter the number used to identify this SNTP
authentication key internally.
• Authentication Key—Enter the key used for authentication (up to eight
characters). The SNTP server must send this key for the switch to
synchronize to it.
• Trusted Key—Select the check box to allow the switch to receive broadcast
synchronization information only from a SNTP server by using this
authentication key.
STEP 6 Click Apply. The SNTP Authentication is defined, and the Running Configuration
file is updated.
