我正在查看工作中的思科交换机日志，对于它有时有多冗长感到有点困惑。
例如，我们在这里使用自动 QoS，当电话插入时我经常会看到这种情况：
Mar 18 15:22:40: %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED: cisco-phone detected on port Fa1/0/9, port's configured trust state is now operational.
Mar 18 15:22:41: %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED: cisco-phone detected on port Fa1/0/9, port's configured trust state is now operational.
Mar 18 15:22:42: %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED: cisco-phone detected on port Fa1/0/9, port's configured trust state is now operational.
Mar 18 15:22:43: %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED: cisco-phone detected on port Fa1/0/9, port's configured trust state is now operational.
Mar 18 15:22:44: %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED: cisco-phone detected on port Fa1/0/9, port's configured trust state is now operational.
Mar 18 15:22:45: %SWITCH_QOS_TB-5-TRUST_DEVICE_DETECTED: cisco-phone detected on port Fa1/0/9, port's configured trust state is now operational.
为什么它会发送六次该垃圾邮件？这是在 WS-C3750V2-24-PS-S 交换机上。如果有什么不同的话，一个堆栈中有 5 个此类交换机运行 IOS 12.2(55)SE3。
端口的配置如下：
Current configuration : 655 bytes

interface FastEthernet1/0/9
switchport access vlan 10
switchport mode access
switchport voice vlan 710

end
答案1
我认为这可能是一个冲突：
auto qos voip cisco-phone
以及其他服务政策：
service-policy input AutoQoS-Police-CiscoPhone
我会尝试删除其中一个，看看会发生什么。在我们的环境中仅运行自动 qos 时没有遇到任何问题。
