HIGH AVAILABILITY VIRTUAL SWITCH

摘要

Method and devices are provided for implementing high availability. Some implementations provide high availability for virtual switches of data networks. Each virtual switch acts as a single logical unit, while encompassing at least two physical chassis, referred to herein as a master chassis and a slave chassis. In some preferred embodiments, the active supervisor in the master chassis is configured as an active supervisor of th e virtual switch and the active supervisor in the slave chassis is configured as the standby supervisor of the virtual switch.
