- BIG-IP system reports an incorrect system time. - Chassis systems might report different system times across blades. - 'ntpq -pn' command reports NTP connection status as 'INIT'. - NTP requests are generated with incorrect source address.


System time mismatch between blades.


Configuration contains both a default route and default management-route.


Configure a user alert to watch for the log message 'notice sod[5460]: 01140044:5: HA reports tmm ready' and then restart ntpd. alert TMM_ready_NTPD_restart "HA reports tmm ready" { exec command="/usr/bin/bigstart restart ntpd" }
