Abstract: A method, apparatus and computer readable medium for reducing traffic loss when bringing up a switch within a multi chassis switch cluster without using dedicated intra cluster links is presented. A first network device in a cluster discovers at least one path to a second network device in the cluster, wherein the cluster utilizes at least one virtual IST between the first network device and the second network device. The first network device starts an Inter Switch Trunk (IST) synchronization process with the second network device. The first network device installs redirection rules, wherein the redirection rules are used for datapath traffic and are not used for control channel traffic. The first network device determines that the IST synchronization process between the first network device and the second network device has completed, and removes the redirection rules.

Abstract translation: 提出了一种用于在不使用专用集群链路的情况下在多机架交换机集群中引入交换机时减少流量损失的方法，装置和计算机可读介质。 集群中的第一网络设备发现至少一个到集群中的第二网络设备的路径，其中集群在第一网络设备和第二网络设备之间利用至少一个虚拟IST。 第一个网络设备启动与第二个网络设备的交换机间中继（IST）同步过程。 第一个网络设备安装重定向规则，其中重定向规则用于数据路径流量，不用于控制信道流量。 第一网络设备确定第一网络设备和第二网络设备之间的IST同步过程已经完成，并且去除重定向规则。
