Verify the Nokia router is configured to compare the internal system clocks on an organization-defined frequency with organization defined authoritative time source. 

Verify NTP server is configured:

- show system ntp detail

If the Nokia router is not configured to compare the internal system clocks on an organization-defined frequency with an organization-defined authoritative time source, this is a finding.

Fix Text

Configure the Nokia router to compare the internal system clocks on an organization-defined frequency with an organization-defined authoritative time source. 

Configure NTP server to be used for timing using the command below:

- configure system time ntp server <NTP server ip address>authentication-key <key id> key <key> type message-digest
