Enabling High Availability Features
Setting the Config-Register Boot Variable
Though it is not required, we recommend that you modify the software configuration register boot field
so that the system boots the same image that the hw-module slot slot-number image file-spec command
specifies in the “Configuring RPR and RPR+” section on page 46.
Configuring RPR and RPR+
Note Online removal of the active RSP causes all line cards to reset and reload, which is the equivalent to an
RPR switchover, and results in a longer switchover time. When it is necessary to remove the active RSP
from the system, first issue a switchover command to switch from the active RSP to the standby RSP.
