组网图是基站-----思科交换机--------freeradius服务器
基站发起认证，发送eapol start报文，交换机已经收到，但是交换器发送的eapol identity request报文的目的mac是组播的,0x0180c2000003，我觉得应该是start报文的源mac才对。
交换机配置如下
aaa new-model
aaa authentication dot1x default group radius
dot1x system-auth-control
identity profile default
identity profile dot1x
radius-server host 10.232.45.14 auth-port 1812 acct-port 1813 key 7 010703174F020808
interface GigabitEthernet1/0/8
authentication host-mode multi-host
authentication port-control auto
dot1x pae authenticator
