You can configure the device to authenticate the time sources to which the local clock is synchronized. When you enable NTP authentication, the device synchronizes to a time source only if the source carries one of the authentication keys specified by the ntp trusted-key command. The device drops any packets that fail the authentication check and prevents them from updating the local clock. NTP authentication is disabled by default.
Make sure that you configured the NTP server with the authentication keys that you plan to specify in this procedure. See the “Configuring an NTP Server and Peer” section for information.
Make sure that you are in the correct VDC. To change the VDC, use the switchto vdc command.
