propagating to the standby. If the active survives AGE minutes of operations with the new
configuration, that configuration is propagated to the standby.
It is not necessary to maintain the current time and date for automatic update to work properly.
However, if date and timezone [6.3.6] are used, an improper setting could cause undue delays in
automatic update. In particular, manually setting the date backwards by a large amount while an
update is pending could cause an update delay of the same amount.
6.9.4 STANDBY LOGS – STBY DLOG, STBY RESET
Two new options have been added to the stby command: dlog and reset.
Syntax: stby dlog
Syntax: stby reset
Two new logs are available on the active system which pertain to the standby system:
1. An alarm log showing the major alarms on the standby system
2. A standby activity log
The first log is viewed by entering any of the commands: vfy stby, stby, or stby vfy.
The second log is viewed by entering the command stby dlog.
Both logs are cleaned out and restarted by entering the command stby reset.
All of the above commands are executed on the
active system.
6.9.5 SWITCHOVER
Syntax: switchover
The switchover command, available only at the active console, forces a switchover to the
standby DT-6X60. The former active DT-6X60 then reboots into standby mode. The reboot
command at the active console simply reboots the active DT-6X60 back to active mode, while the
standby DT-6X60 allows a little extra time for the active to complete the reboot.
