SNTP Configuration
Fixed Switch Configuration Guide 4-13
Use the set sntp authentication key command to configure an authentication key instance.
The SNTP authentication key is associated with an SNTP server using the set sntp server
command.
An authentication key has to be trusted to be used with an SNTP server. Use the set sntp trusted-
key command to add an authentication key to the trusted key list.
Refer to Procedure 4-3 on page 4-14 to configure the switch SNTP client for authentication.
