A switch can be configured to act as an
NTP
client, or an
NTP
client/server. An
NTP
client
receives updates from an
NTP
server without passing on time information to other clients,
while and
NTP
client/server receives time information from a server, and acts as a server for
other clients in a higher stratum.
Configuring an NTP Client
To set up the NTP client, use the
ntpiconfig
command as follows:
1. Enter the command as shown, at the system prompt:
ntpiconfig
The following menu appears:
NTP Startup Configuration
1) Response timeout : 0
2) Authentication delay : No
3) Authentication key file name : UNSET
4) NTP client mode : Ucast
5) Enable monitor : No
6) Enable NTP server : No
2. Adjust the configurable variables for this
NTP
client as needed by entering the line
number, and equal sign, and a new value at the system prompt, as shown:
<lineNumber>=<value>
For example, to change the
Response timeout
to 10, you would enter
1
(the line number
for
Response timeout
), an equal sign (
=
), and the number
10
(the new value), as shown:
1=10
After enabling
NTP
for this switch, you need to configure at least one peer association, unless
you will be supplying time synchronization. In that case, you need to configure a reference
clock.
For information on adding a peer association, see Configuring a New Peer Association on
page 12-12.
