Usage Guidelines
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment is
preventing you from using a command, contact your AAA administrator for assistance.
The subscriber redundancy activate command is currently not supported.
In most cases, the switchovers are triggered automatically by changes in the underlying access interfaces or
due to other failures. This command is used for planned maintenance events or for exceptional cases where
implementation of access-tracking is not possible or desired. It can be used to initiate switchover for all groups
on the router, or on a particular location or for a specific SRG.
Switchover is triggered from the slave only when you choose the force option. The use of this option on
either master or slave overrides any negotiation or arbitration rules.
Even for manual (or admin-triggered) switchovers, it is highly recommended to initiate triggers through
operations on the underlying access, to ensure consistency between the BNG and access roles or status. When
switchover happens, logs that indicate the reason of the switchover, are generated on the system console and
