路由器8806无法telnet

故障现象：

 

对路由器发起telnet 远程后，界面无任何反应。

 

去现场接console口，进去Telnet 自己测试也是 界面提示 大意是 链接的用户超出。

 

原来vty是 0 4 ；改成vty 0 10 ,也是同样提示。

 

去查看line 用户数是0。

 

配置里面vty 没有配置in 或者out 方向限制。

 

Telnet 未配置端口号。

 

Telnet 服务器已经开启。

 

用户下Telnet权限也给了。

 

用户权限级别是net-admin

 

从远程telnet  这台服务器任何地址都是界面无任何显示。

 

近期发现别的2台8808也是同样的现象。

 

麻烦各位工程帮忙解决一下，提供一下排障方法。

 

有问题的那台是核心网络，也不敢重启。但是网络是正常的。
