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

    摘要: Various methods and systems for preventing erroneous link aggregation due to component relocation are disclosed. Such methods include a method for changing the identifier used by a network device and communicating the identifier change to a peer network device without disrupting an aggregated link. In one embodiment, a method involves detecting an identifier change and sending a Port Aggregation Protocol (PAgP) protocol data unit (PDU) that includes a new identifier and information. The information indicates the identifier change. The new identifier identifies a network device subsequent to the identifier change. Another embodiment of a method involves detecting an identifier change and, subsequent to the identifier change, sending a link aggregation protocol PDU that includes an “old device identifier” field dedicated to conveying an old identifier. The old identifier identifies a network device prior to the identifier change.
