ACs support hot-standby backup. Two hot-standby backup modes are available: HSB+VRRP and HSB+dual-link backup. HSB+VRRP backup implements traffic switching through VRRP, while HSB+dual-link backup implements traffic switching through dual links. Hot-standby backup achieves service backup of two ACs. HSB+VRRP applies only to the active/standby mode, whereas HSB+dual-link backup applies to both the active/standby and load balancing modes.
