Description

timezone timezone keyword For a list of time zones that you can enter, see Table 11.

auto_daylight Y or N Enables or disables automatic adjustment for daylight savings time.

resolv_ipv6_ddress Y or N Specifies whether or not the VPN firewall automatically resolves a domain name for an NTP server to an IPv6 address:

• Y. A domain name is resolved to an IPv6 address.

• N. A domain name is resolved to an IPv4 address.

ntp_mode Authoritative_Mode, Sync_to_NTP_Servers_on _Internet, or

Sync_to_NTP_Servers_on _VPN

Specifies the NTP mode:

• Authoritative_Mode. The VPN firewall synchronizes its clock with the specified NTP server or servers on the Internet. If external servers are unreachable, the VPN firewall’s real-time clock (RTC) provides time service to clients. Issue the stratum keyword to specify the stratum value. As an option, issue the set_date_time_manually value keyword to enable manual configuration of the date and time.

• Sync_to_NTP_Servers_on_Internet. The VPN firewall synchronizes its clock with the specified NTP server or servers on the Internet. If external servers are unreachable, the VPN firewall does not use its RTC.

• Sync_to_NTP_Servers_on_VPN. The VPN firewall synchronizes its clock with the specified NTP server on the VPN. If the server is unreachable, the VPN firewall does not use its RTC. Issue the vpn_policy keyword to specify a VPN policy that enables the VPN firewall to contact the NTP server on the VPN.

stratum number If the ntp_mode keyword is set to

Authoritative_Mode, the stratum value.

This value indicates the distance between the RTC of the VPN firewall and a reference clock.

set_date_time_manually Y or N Enables or disables manual configuration of the date and time. If you enable manual

configuration, issue the ntp_hour, ntp_minutes, ntp_seconds, ntp_day, ntp_month, and ntp_year keywords to specify the date and time manually.

ntp_hour hour The hour in the format HH (00 to 24) for manual configuration.

ntp_minutes minutes The minutes in the format MM (00 to 59) for manual configuration.

ntp_seconds seconds The seconds in the format SS (00 to 59) for manual configuration.

ntp_day day The day in the format DD (00 to 31) for manual configuration.

ntp_month month The month in the format MM (01 to 12) for manual configuration.

ntp_year year The year in the format YYYY for manual configuration.

Keyword Associated Keyword to Select or Parameter to Type

Description

vpn_policy vpn policy name If the ntp_mode keyword is set to

Sync_to_NTP_Servers_on_VPN, the name of the VPN policy that enables the VPN firewall to contact the NTP server on the VPN.

use_default_servers Y or N Enables or disables the use of default NTP servers.

configure_ntp_servers Y or N Enables or disables the use of custom NTP servers. If you enable the use of custom NTP servers, you need to specify the server IP addresses or domain names with the ntp_server1 and ntp_server2 keywords.

ntp_server1 ipaddress or domain name The IP address of domain name of the first custom NTP server.

ntp_server2 ipaddress or domain name The IP address of domain name of the second custom NTP server.
