A.In the business function LOG_MM_CL1 B.In the purchasing group C.In the vendor master record D.In the personal setting of the purchase order E.In the parameter EVO 此题为多项选择题。

A.SSID技术可以将一个无线局域网分为几个需要不同身份验证的子网络，每一个子网络都需要独立的身份验证，只有通过身份验证的用户才可以进入相应的子网络，防止未被授权的用户进入本网络。B.BSSID实际上就是AP的MAC地址，用来标识AP管理的BSS，在同一个AP内BSSID和SSID一一映射。C.用户可以在不同的SSID下面实现漫游。D.在一个ESS内SSID是相同的，但对于ESS内的每个AP与之对应的BSSID是不相同的。如果一个AP可以同时支持多个SSID的话，则AP会分配不同的BSSID来对应这些SSID。
