Authentication-key
The authentication-key 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.
A:sim1>config>system>time>ntp# info
----------------------------------------------
shutdown
authentication-key 1 key "OAwgNUlbzgI" hash2 type des
----------------------------------------------
A:sim1>config>system>time>ntp#
Broadcast
The broadcast command is used to transmit broadcast packets on a given interface.
Interfaces in the base routing context or the management interface may be specified. Due the
relative ease of spoofing of broadcast messages, it is strongly recommended to use
authentication with broadcast mode. The messages are transmitted using a destination address
that is the NTP Broadcast address.
CLI Syntax: config>system>time>ntp
broadcast [router router-name] {interface
ip-int-name} [key-id key-id] [version
version]
[ttl ttl]
Example: config>system>time>ntp#
