Abstract: In one embodiment, an exploratory linktrace is initiated from an initiating network device with an exploratory linktrace message (ELM) having a target address. Each network device receiving the ELM may then propagate the ELM on a plurality of its ports to a plurality of downstream network devices based on the target address. In addition, each receiving network device returns an exploratory linktrace reply (ELR) for each of the plurality of ports, where each ELR is returned according to one or more mechanisms to mitigate stormed replies to the initiating network device.

Abstract translation: 在一个实施例中，从具有目标地址的探索链路跟踪消息（ELM）的发起网络设备发起探索性链路跟踪。 接收ELM的每个网络设备然后可以基于目标地址将多个其端口上的ELM传播到多个下游网络设备。 另外，每个接收网络设备返回针对多个端口中的每一个的探索性链路跟踪应答（ELR），其中根据一种或多种机制返回每个ELR，以减轻对发起网络设备的暴风骤雨的回复。
