Specify the address of the remote system. You must specify an address, not a hostname.
To include an authentication key in all messages sent to the remote system, include the
key
option. The key corresponds to the key number you specify in the
authentication-key
statement, as described in “Configuring NTP Authentication Keys” on page 18 .
By default, the router or switch sends NTP version 4 packets to the remote system. To
set the NTP version level to 1, 2 or 3, include the
version
option.
If you configure more than one remote system, you can mark one system preferred by
including the
prefer
option:
peer address <key key-number> <version value> prefer;
Configuring the Router or Switch to Operate in Broadcast Mode
To configure the local router or switch to operate in broadcast mode, include the
broadcast
statement at the
[edit system ntp]
hierarchy level:
[edit system ntp]
broadcast address <key key-number> <version value> <ttl value>;
Specify the broadcast address on one of the local networks or a multicast address
assigned to NTP. You must specify an address, not a hostname. If the multicast address
is used, it must be
224.0.1.1
.
To include an authentication key in all messages sent to the remote system, include the
key option. The key corresponds to the key number you specify in the authentication-key
statement, as described in “Configuring NTP Authentication Keys” on page 18 .
By default, the router or switch sends NTP version 4 packets to the remote system. To
set the NTP version level to 1, 2, or 3, include the
version option.
Configuring the Router or Switch to Operate in Server Mode
In server mode, the router or switch acts as an NTP server for clients when the clients are
configured appropriately. The only prerequisite for “ server mode” is that the router or
switch must be receiving time from another NTP peer or server. No other configuration
is necessary on the router or switch.
To configure the local router or switch to operate as an NTP server, include the following
statements at the
[edit system ntp] hierarchy level:
[edit system ntp]
authentication-key key-number type type value password;
server address <key key-number> <version value> <prefer>;
trusted-key [ key-numbers ];
Specify the address of the system acting as the time server. You must specify an address,
not a hostname.
To include an authentication key in all messages sent to the time server, include the
key
option. The key corresponds to the key number you specify in the
authentication-key
statement, as described in “Configuring NTP Authentication Keys” on page 18 .
