User Access Multi-Device Backup Configuration
Multi-device backup can be configured to back up user information, improving service reliability.
In VS mode, this feature is supported only by the admin VS.
User Access is only supported on NetEngine 8000 F1A.
- Overview of Multi-Device Backup
- In user information multi-device backup, a VRRP group can be created to achieve BRAS user information backup. In this manner, services can be flexibly controlled and managed.
- Configuring Multi-Device Backup for IPv4 User Information
- After multi-device backup of IPv4 user information is enabled, users do not need to re-dial up, QoS scheduling remains unchanged, accounting information is not lost, and users can go online through new locations after a master/backup BRAS switchover.
- Configuring Multi-Device Backup for IPv6 BRAS User Information
- After multi-device backup of BRAS user information is enabled on IPv6 networks, users do not need to re-dial up, QoS scheduling remains unchanged, accounting information is not lost, and users can go online through new locations after a master/backup BRAS switchover.
- Configuring Multicast Dual-Device Hot Backup
- Configuring multicast dual-device hot backup improves multicast service reliability.
- Configuring L2TP Dual-Device Hot Backup
- L2TP dual-device hot backup can be configured on LACs to improve L2TP access reliability. With L2TP dual-device hot backup, users can log in again without the need of re-dialing up if a network fault occurs. A RADIUS server cannot deliver the Tunnel-Client-Endpoint attribute during L2TP hot backup configuration.
- Maintaining Multi-Device Backup
- By running the display and reset commands, you can check and clear desired backup information.
- Configuration Examples
- This section provides configuration examples of multi-device backup. Each configuration example consists of information such as the networking requirements, configuration precautions, and configuration roadmap.
