The Juniper SRX Services Gateway must be configured to synchronize internal information system clocks with the primary and secondary NTP servers for the network.

The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on log events and other functions.

Multiple time sources provide redundancy by including a secondary source. Time synchronization is usually a hierarchy; clients synchronize time to a local source while that source synchronizes its time to a more accurate source. The network device must utilize an authoritative time server and/or be configured to use redundant authoritative time sources.

Verify the Juniper SRX is configured to synchronize internal information system clocks with the primary and secondary NTP sources.

[edit] show system ntp

If the Juniper SRX is not configured to synchronize internal information system clocks with an NTP server, this is a finding.

The following commands allow the device to keep time synchronized with the network. To designate a primary NTP server, add the “prefer” keyword to the server statement.

[edit] set system ntp server <NTP-server1-IP> prefer set system ntp source-address <MGT-IP-Address> set system ntp server <NTP-server2-IP> set system ntp source-address <MGT-IP-Address>
