为什么在主机不支持认证时，从guest-vlan获取到ip地址时间需要十几分钟，那么久
Ccisco 3560 上dot1x配置 aaa new-model aaa authentication dot1x default group radius
aaa authorization network default group radius
radius-server host 192.168.1.2 key 123456
dot1x system-auth-control
dot1x guest-vlan supplicant
interface GigabitEthernet0/4
switchport mode access
authentication event fail action authorize vlan 10
authentication event no-response action authorize vlan 10
authentication port-control auto
dot1x pae authenticator
spanning-tree portfast
