This topic describes how to view the WAN + 4G backup of a Smart Access Gateway (SAG). By default, WAN + 4G backup is enabled for SAG-100WM and SAG-1000 to use wired broadband as the active link and wireless 4G-LTE as the standby link. If the active link fails, the system automatically switches to the standby link.
- Log on to the Smart Access Gateway console.
- In the left-side navigation pane, clickSmart Access Gateway, and then click the instance ID of the SAG for which you want to perform an active/standby switchover.
- In the left-side navigation pane of the SAG details page, click HA Configuration.
- On the HA Configuration page, view the current active and standby links of the SAG in the WAN + 4G area.
The HA structure of SAG-100WM and SAG-1000 is displayed, as shown in the following figure.
