Abstract: A feature trace capability may be provided for features including, but not limited to, automatic quality of service (auto QoS), power over Ethernet (PoE), and fabric compatibility. A network command may be implemented with the capability to validate features across a network path or the network as a whole. The output of this network command may result in the display of details about supported features. Such a command may also result in a listing of what devices require upgrades to support any number of features of interest. Embodiments of the feature trace capability may be configured such that the query gets terminated once a final subnet (or endpoint) is reached. Alternatively, the feature trace capability may be configured such that the query gets terminated after a maximum hop count, or trace total (trace_ttl) is reached. Such a limit may prevent the continuous flooding of the network.

Abstract translation: 可以为特征提供特征追踪功能，包括但不限于自动服务质量（自动QoS），以太网供电（PoE）和结构兼容性。 可以实现网络命令，其具有通过网络路径或网络整体验证特征的能力。 此网络命令的输出可能会显示关于支持的功能的详细信息。 这样的命令还可以列出什么设备需要升级来支持任何数量的感兴趣的特征。 可以配置特征跟踪能力的实施例，使得一旦达到最终子网（或端点），则查询终止。 或者，可以配置特征跟踪能力，使得在达到最大跳数或跟踪总数（trace_ttl）之后，查询终止。 这样的限制可以防止网络的连续洪泛。
