Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G06F 11/00
US Classification:
714 12, 713 1
Abstract:
A system and method for supporting a “hitless” switchover from an Active to a Standby processor utilizes several points of configuration synchronization. The startup and running configuration files are copied to the Standby processor and subsequent modifications to the Active configuration are synchronized to the Standby configuration.

Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
G06F 9/45
US Classification:
717168
Abstract:
Methods and devices are provided for maintaining configuration synchronization when an Active unit and a Standby unit have different versions of a software image. Preferred implementations allow the system to operate in a stateful mode even after the Standby unit has had an image upgrade. Other implementations allow the system to operate in a stateful mode when the Active unit has a higher-level version of the image than the Standby unit.
