First Claim
Patent Images
1. A method of providing high availability for a network, the method comprising:
- configuring a first supervisor in a first chassis of a virtual network device as an active supervisor;
configuring a second supervisor in a second chassis of the virtual network device as a standby supervisor for the virtual network device; and
configuring a third supervisor as first pseudo-standby supervisor kept in a warm state.

Abstract
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 the virtual switch and the active supervisor in the slave chassis is configured as the standby supervisor of the virtual switch.
