我在使用 Catalyst 6509、2XSUP7203BXL 和 2XWS-X6704-10GE 时遇到了一个奇怪的问题。在使用静态路由进行初始配置、注入数据包或针对我的路由器测试 ddos 后，在 Tengigabit 接口中使用 250-300 mbit 和 50.000 个数据包甚至更少后，它开始增加 CPU 使用率，并在 10 秒内冻结，或多或少. 检查cpu使用情况，IP INPUT一直在使用cpu，我认为是软件切换，对吗？
我尝试将 ios 升级到 15.1，将 IOS 降级到 12.2（2009 版）并使用 IOS 12.2（2014 年 9 月）并将光纤移动到另一个 6704-10GE 卡，但没有运气，另一个模块中的行为相同。我的卡安装在 SLOT 1 和 Slot 4 中，我听说 6513 有限制，但 6509 没有。
