Usage Guidelines
•
Use the no form of this command to delete the specified server.
•
To configure NTP in the client mode you must first define the NTP servers. Up to 3 NTP servers may
be defined.
•
Either an IP address or domain name for the specified server can be entered.
•
The NTP key identification is an integer. It corresponds to an MD5 authentication key contained in an
authentication file (.txt) located on the server. This file must be on both the server and the local switch,
and match, for authentication to work. Enter the key identification using the
key keyword if the server
is set to MD5 authentication.
