请问各位大神，我客户装了几个无线ap，非cisco产品，然后在cisco交换机发生环路，估计无线漫游导致，我查了一下文档，其中说，请问下面这个TP 是什么意思？是STP吗？
I see the error message : %C4K_EBM-4-HOSTFLAPPING:Host [mac-addr] in vlan [num] is flapping between port [num] and port [num] connected to the Access Points. How do we resolve this?
A. This error message occurs when switch learns the same MAC address through multiple ports. This can be due to one of these reasons
When a client roams from one AP to another AP, the new AP informs the client of the MAC address to the switch. If both the APs are connected to the same switch, the MAC address of the client is associated to both the switch ports connected to the APs. This creates a duplicate entry for the client and generates this error message until the time that the switch synchronizes its CAM table. This error message is quite normal in a wireless environment, but, if too much roaming occurs, this can overload the CPU of the switch. Check the client driver and firmware. In addition, ensure that coverage is good so that the client does not roam often.
When there is a loop, the switch can learn the same MAC address through multiple ports connected to other switches. Ensure that the TP is enabled on the switch.
