Configuring hot backup
To implement hot backup for two LB devices, you must enable synchronization for session extension information and sticky entries to avoid service interruption.
For successful sticky entry synchronization, if you want to specify a sticky group, enable sticky entry synchronization before specifying a sticky group on both LB devices. You can specify a sticky group by using the sticky sticky-name option when you specify a primary server farm (see "Specifying a primary server farm).
To configure hot backup:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter virtual server view. | virtual-server virtual-server-name | N/A |
3. Enable session extension information synchronization. | connection-sync enable | By default, session extension information synchronization is disabled. |
4. Enable sticky entry synchronization. | sticky-sync enable | By default, sticky entry synchronization is disabled. |
