Abstract
Official abstract text for this publication.
A method performed by network devices that includes operating in a normal mode, where the network devices form a virtual chassis that corresponds to a single logical network device; detecting when a failure within the virtual chassis occurs; executing a splitting process to form one or more new virtual chassis in correspondence to the failure; determining whether one of the one or more new virtual chassis operates as a functioning virtual chassis based on whether at least one of a set of criteria is satisfied, where the functioning virtual chassis operates according to resources configured for the virtual chassis; and operating as a nonfunctioning virtual chassis when it is determined that the one of the one or more virtual chassis does not satisfy the at least one of the set of criteria, where the nonfunctioning virtual chassis operates in a pass-through mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: determining, by one or more devices, a first size of a first virtual chassis; determining, by the one or more devices, a second size of a second virtual chassis; determining, by the one or more devices, that a particular condition is satisfied based on the first size and the second size; determining, by the one or more devices, that the first virtual chassis is able to operate as a functioning virtual chassis based on the particula…
