SNTP: Viewing, Selecting, and Configuring
Associating a Key with an SNTP Server
After a key is configured, it must be associated with a specific server.
Syntax
:
[no] sntp server priority <1-3> <ip-address | ipv6-address> <version-num>
[key-id <1-4,294,967,295>]
Configures a key-id to be associated with a specific server. The
key itself must already be configured on the switch.
The no version of the command disassociates the key from the
server. This does not remove the authentication key.
Default: No key is associated with any server by default.
priority: Specifies the order in which the configured servers
are polled for getting the time. Value is between 1 and 3.
<version-num>: Specifies the SNTP software version to use, and
is assigned on a per-server basis. The version setting is
backwards-compatible. For example, using version 3 means
that the switch accepts versions 1 through 3.
Default: 3; range: 1 - 7.
key-id: Optional command. The key identifier (range 1-
4,294,967,295) sent in the SNTP packet. This key-id will be
associated with the SNTP server specified in the command.

Enabling SNTP Client Authentication
The sntp authentication command enables SNTP client authentication on the
switch. If SNTP authentication is not enabled, SNTP packets are not authen-
ticated.
Syntax
:
[no] sntp authentication
Enables the SNTP client authentication.
The no version of the command disables authentication.
Default: SNTP client authentication is disabled by default.
