Defining SNTP Authentication

Cisco Small Business 200 1.1 Series Smart Switch Administration Guide

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.
