Switchover (CLI)
The following events trigger switchover for unit redundancy according to their priority, with the highest priority
triggers listed first.
1. Loss of active unit
2. Force switch
3. Lockout
4. Radio Loss of Frame (LOF) on active unit
5. Change request from the remote unit. This takes place in the event of radio LOF on both units; a change
request is sent to the active unit on the other side of the link.
6. Loss of Carrier (LOC) in any of the Ethernet interfaces or Loss of Signal (LOS) in any of the TDM interfaces
7. Manual switch
LOC takes place if the Admin status of the interface is Enabled and the Operational status is Down. If the interface
is closed as a result of ASP, the interface is not considered to be in LOC state, and switchover is not triggered.
Following switchover triggered by LOC, there is an automatic timeout of one minute before any further switchover
can take place due to LOC.
At any point, you can manually switch to the standby unit, provided that the highest protection fault level in the
standby unit is no higher than the highest protection fault level on the active unit.
You can also perform a force switch to the standby unit, even if the protection fault level is higher in the standby
unit. Force switch also implements lockout.
To perform a manual switch, enter the following command in root view:
