S5130S-EI交换机通过标杆的神器备份配置失败问题

使用标杆神器备份S5130S-EI交换机配置提示失败，提示执行设备通信模块失败，连接失败，错误码108，其他设备都正常备份成功。

测试可以互通；

通过debug信息发现报错ssh版本不一致，版本就V1/V2两种，联系标杆侧确认目前软件备份配置使用SSH1去获取，设备侧需要兼容SSH1即可，于是查看设备手册发现设备侧由此兼容SSH1功能，但是默认关闭

开启后正常，

debug信息如下

其他设备正常，是由于该功能默认开启导致，目前发现只有S5130S-EI、S5130S-HI交换机默认关闭。

在设备侧修改配置，添加SSH兼容SSH1版本后正常

 设置SSH服务器兼容SSH1版本的客户端。

ssh server compatible-ssh1x enable

缺省情况下，SSH服务器不兼容SSH1版本的客户端

1、问题故障可以对比设备不同点；

2、必要时设备侧收集debug信息确认原因。
