No NTP servers are configured by default.
NOTE:
Incoming
NTP packets
require administrative
access. If the administra-
tive IP address ACL (dis-
abled by default) is
enabled, it must include
IP addresses for the NTP
server(s). See Section
2.2.5 for more detail.
Traffic is affected by the
per-interface packet fil-
ters. If configured, per-
interface packet filters
must include filters to
permit NTP traffic to
and from the FMP. See
Section 4.6.3 for more
detail.
NTP servers are specified by local ServerName (or -name), as
primary
, secondary, and tertiary, and added to the Mesh
Point configuration by network IP address or hostname
(
IPorHostname, or -ip).
The
Active (or -enable) parameter permits you to control
whether or not a configured NTP server is currently in use by
the Mesh Point’s NTP client function.
Optionally, you can configure the Mesh Point to use RSA SHA1
to authenticate incoming NTP packets from a configured NTP
server by specifying
y
(
es
) for AuthEnabled
(
-auth y) for the server. In order for the Mesh Point to
successfully authenticate NTP packets from a configured
server, you must also specify a key index value for the server
with
AuthKeyIndex (-keyindex). Specify a valid index value
from
1
to
65534
.
Configure a new NTP server for the Mesh Point or change the
settings of an existing server interactively with
set ntp:
# set ntp
ServerName (primary|secondary|tertiary to select server):primary|secondary|tertiary
IPorHostname (IP address or name of the server:
<NTPsrvrIPaddr>
|
<NTPsrvrHostname>
Active (Y|N to enable|disable the server):y|n
AuthEnabled (Y|N to enable|disable SHA1 authentication):y|n
AuthKeyIndex (specifies which key the server expects the client to authenticate
with (valid indices: 1-65534; set 0 or 65535 to invalidate index)):0|1-65534
Alternatively, you can use the command non-interactively to
specify any of the same settings:
# set ntp -name primary|secondary|tertiary -ip
<NTPsrvrIPaddr>
|
<NTPsrvrHostname>
|""
-enable y|n -auth y|n -keyindex 0|1-65534
