Use the following procedure to edit the NTP MD5 Authentication screen:
Enter a value from 0 to 65534 in the Key ID text box. You must enter a number that is not already used.
Enter up to 32 ASCII characters in the Key Value text box. Most of the printable ASCII characters are allowed. Characters not allowed are double quotation mark, comma, colon, semicolon, and back slash.
Click OK to accept changes and return to the NTP Authentication screen, or Cancel to return to the NTP Authentication screen without saving changes.
Note: For all changes made in this window to take effect, you must click Apply in the screen.
Note: To minimize disruption of NTP service, make all changes to all menus first and then click Apply in the screen. Each time you click Apply, the NTP card stops service for 30 seconds as the card re-configures to its new setting.
