刚装一台2960S，版本12.2(55)SE8，配置dot1X后无法认证具体如下：
配置：
aaa new-model
aaa authentication login default line none
aaa authentication dot1x default group radius
aaa authorization network default group radius
dot1x system-auth-control
interface GigabitEthernet1/0/1
switchport mode access
authentication port-control auto
dot1x pae authenticator
spanning-tree portfast
radius-server host 172.16.70.51 auth-port 1812 acct-port 1813 key phfund
radius-server host 172.16.70.48 auth-port 1812 acct-port 1813 key phfund
radius-server retry method reorder
radius-server timeout 3
radius-server deadtime 3
radius-server vsa send authentication
接入PC后抓包：

在radius服务器上没有数据过来。
show：
