Dual-Link Backup FAQs
Solution
1) In a dual-link backup network, the device model and software version need to be consistent.
2) In a dual-link network, for the convenience of configuration, you can only install the license on the active AC, and not install the license on the standby AC. The standby AC shares the AP license to ensure that the license is still available when the active AC fails.
3) In a dual-link backup and AP license sharing network, when one AC is disconnected for more than 30 days, its shared AP license will become invalid on the other AC, and the newly connected AP cannot use the shared AP license. AP license, the connected AP will not be kicked offline.
After R5443, after the main AC fails, the AP switches from the main AC to the backup AC; after the main AC recovers, it takes at least 10 minutes for the AP to switch back to the main AC from the backup AC.
