CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
■ [0] = Disable
■ [1] = (Default) Normal
■ [2] to [10] = Fast
When set to 0, the DHCP lease renewal is disabled. Otherwise,
the renewal time is divided by this factor. Some DHCP-enabled
routers perform better when set to 4.
Note: For the parameter to take effect, a device reset is required.
NTP and Daylight Saving Time Parameters
The Network Time Protocol (NTP) and daylight saving time parameters are described in the table
below.
Table 60-15:NTP and Daylight Saving Time Parameters
Parameter Description
NTP Parameters
CLI path: configure system > ntp
Note: For more information on Network Time Protocol (NTP), see Simple Network Time
Protocol Support .
'Primary NTP Server Address'
primary-server
[NTPServerIP]
Defines the IP address (in dotted-decimal notation or as an
FQDN) of the NTP server. The advantage of using an FQDN
is that multiple IP addresses can be resolved from the DNS
server, providing NTP server redundancy.
The default IP address is 0.0.0.0 (i.e., internal NTP client is
disabled).
'Secondary NTP Server
Address'
secondary-server
[NTPSecondaryServerIP]
Defines a second NTP server's address as an FQDN or an
IP address (in dotted-decimal notation). This NTP is used for
redundancy; if the primary NTP server fails, then this NTP
server is used.
The default IP address is 0.0.0.0.
'NTP Update Interval'
update-interval
[NTPUpdateInterval]
Defines the time interval (in seconds) that the NTP client
requests for a time update.
The default interval is 86400 (i.e., 24 hours). The range is 0 to
214783647.
Note: It is not recommend to set the parameter to beyond one
month (i.e., 2592000 seconds).
'NTP Authentication Key
Identifier'
auth-key-id
[NtpAuthKeyId]
Defines the NTP authentication key identifier for
authenticating NTP messages. The identifier must match the
value configured on the NTP server. The NTP server may
have several keys configured for different clients; this
number identifies which key is used.
The valid value is 1 to 65535. The default is 0 (i.e., no
authentication is done).
