我已经在centos 6.8上设置了一个radud服务器，我有一个交换机，我想调用这个radius服务器进行身份验证。交换机IP地址是10.2.1.4，它位于客户端配置文件中。这是我的客户端配置文件的一部分
client switch {
ipaddr = 10.2.1.4
secret = testing123
nastype = other
}
以下是我得到的错误
... adding new socket proxy address * port 55146
Listening on authentication address * port 1812
Listening on accounting address * port 1813
Listening on command file /var/run/radiusd/radiusd.sock
Listening on authentication address 127.0.0.1 port 18120 as server inner-

Listening on proxy address * port 1814

有人可以帮我吗？
