These switches , however , will cost more than Layer 2 switches .

但这些交换机要比第2层交换机贵。

In this paper , a new cluster management system is described by proposing a new protocol , with this protocol layer 2 and layer 3 switches can be managed in a cluster system seamlessly .

本文以协议的形式提出了一种新的以太网交换机集群管理方案，将二层交换机和三层交换机的集群管理无缝地结合在一起。
