问题描述:客户同时采购AR1200-S 路路由器器和S5724TP-SI 交换机组建公司⼩小型园区⽹网络,⾸首次使⽤用SecureCRT 终
端⼯工具通过串串⼝口线本地登陆对设备进⾏行行配置,SecureCRT 默认配置,登陆AR1200-S 路路由器器⼀一切正常,
同样的串串⼝口线、PC 和终端⼯工具登陆S5700 交换机只能输出信息,却完全⽆无法输⼊入命令⾏行行进⾏行行操作。

处理理过程
1、客户最开始使⽤用的是标配AR1200-S 路路由器器的串串⼝口线登陆S5700 交换机,换成S5700 标配的串串⼝口线
后问题重现,同时这条串串⼝口线登陆AR 路路由器器正常,排除串串⼝口线问题;
2、S5700 交换机console ⼝口损坏,重启交换机,重启过程的打印信息输出正常,且交换机启动⼀一切正

排除console ⼝口损坏;
3、检查SecureCRT 登陆配置,客户采⽤用默认配置:

流控选项⾥里里选择了了RTS/CTS,将此流控选项去掉,保证流控为⽆无,之后再次登陆S5700 交换机,恢复
正常,可以正常输⼊入输出,进⾏行行配置等操作。
根因
1、串串⼝口线损坏
2、S5700 交换机console ⼝口损坏
3、SecureCRT 设置错误
建议与总结
采⽤用SecureCRT 终端⼯工具本地登陆AR 路路由器器与S5700 交换机时,流控选项⾥里里,勾选RTS/CTS 时,
登陆AR 路路由器器正常,但是对于S5700 交换机,必须将流控位全部去掉,才能正常登陆交换机。建议
采⽤用SecureCRT 登陆AR 路路由器器和S 系列列盒式交换机时,流控位全部勾掉,可保证都能正常登陆。
