  该问题极可能是由于Cisco 2960X启用了 MAC地址表老化 或 未正确转发未知单播 导致S7510无法持续与电脑通信。虽然清除ARP后短时间内通畅，但由于2960可能在未收到电脑回复的ARP或ICMP后丢弃了转发路径，通信中断。建议检查以下几点：1）确认2960上的端口为access模式并启用端口fast模式，避免环路检测等机制干扰；2）关闭或调整端口上的安全策略如port-security和storm-control；3）尝试在2960和7510的接口上配置双向静态ARP，或在7510上绑定MAC与IP；4）确认S7510接口是否启用了老化保护或某种源MAC检查机制。此类问题多半是交换设备间转发控制或表项老化引发的单向不通。
