Authentication-key
This command configures an authentication key-id, key type, and key used to authenticate NTP 
PDUs sent to and received from other network elements participating in the NTP protocol. For 
authentication to work, the authentication key-id, authentication type and authentication key value 
must match.
CLI Syntax: config>system>time>ntp
authentication-key key-id {key key} [hash | hash2] type 
{des|message-digest}
Example
:
config>system>time>ntp# 
config>system>time>ntp# authentication-key 1 key A type des
config>system>time>ntp# no shutdown
The following example shows NTP disabled with the 
authentication-key 
parameter 
enabled.

broadcast
 command is used to transmit broadcast packets on a given subnet. 
CLI Syntax: config>system>time>ntp
broadcast [router router-name] {interface 
ip-int-name> [key-id key-id]  [version version]
[ttlttl]
Example
:
config>system>time>ntp# 
config>system>time>ntp# broadcast interface int11 version 4 
ttl 127
config>system>time>ntp# no shutdown
The following example in the 
system>time
 context shows NTP enabled with the 
broadcast
 
command configured.
A:sim1>config>system>time# info detail
