Telnet失败

交换机前几天还可以正常Telnet和Web，今天突然不行了，但可以拼通，Console正常，Telnet会报错：

PC1配IP：10.22.0.10/24，接在 0/0/0 口，Telnet、Web该交换机，均正常

PC2配IP：192.168.152.90/24，接在 1/0/24 口，拼该交换机正常回包，Telnet该交换机，会有报错

lookupAccountName<> failed. Error 1332 正在连接 192.168.152.1 ...无法打开到主机的连接。在端口 23：连接失败

PC3配IP：192.168.152.200/24，接在 1/0/23 口，拼该交换机正常回包，Telnet该交换机，连接失败，无其它详细信息

 下面是交换机配置：
