主流技术&(IPS/FW/主备-主主快速切换）

一、RBM主备方案

RBM-FW-P 主配置内容介绍-注释

1. remote-backup group 含义：定义了一个远程备份组。这表明设备支持某种形式的远程备份功能，用于在设备之间同步配置或数据。
2. data-channel interface GigabitEthernet1/0/11 含义：指定用于远程备份的数据通道接口为GigabitEthernet1/0/11。 作用：备份数据将通过这个接口发送到远程设备，确保备份操作的数据传输路径明确。
3. configuration sync-check interval 12 含义：设置配置同步检查的间隔时间为12秒。 作用：设备会每隔12秒检查一次配置是否需要同步，确保本地和远程设备的配置保持一致。
4. delay-time 5 含义：设置延迟时间为5秒。 作用：在执行某些操作（如备份或同步）之前，会延迟5秒。这可能是为了避免网络瞬时问题或确保设备状态稳定后再进行操作。
5. local-ip 10.100.2.1 含义：指定本地设备的IP地址为10.100.2.1。 作用：这是本地设备在网络中的标识，用于与其他设备通信。
6. remote-ip 10.100.2.2 含义：指定远程设备的IP地址为10.100.2.2。 作用：这是远程备份设备的IP地址，本地设备会通过这个IP地址与远程设备通信，进行数据备份或配置同步。
7. device-role primary 含义：指定本地设备的角色为“主设备”。 作用：在备份组中，主设备通常负责发起备份操作或作为主要的配置管理设备。如果存在备用设备，备用设备可能会在主设备故障时接管其功能。

二、RBM主主方案介绍

FW-RBM-P配置

1、加上 RBM_P[FW-RBM-S-remote-backup-group]backup-mode dual-active //RBM从主备切换到主主的方案

FW-RBM-S配置

1、删除 RBM_P[FW-RBM-S-remote-backup-group]undo device-role secondary

2、加上 RBM_P[FW-RBM-S-remote-backup-group]backup-mode dual-active //RBM从主备切换到主主的方案

三、RBM从主主切换到主备
