Does hot standby require a license


The hot standby function does not require a license.

If other services require a license, ensure that licenses with the same specifications are activated on both the active and standby firewalls. Otherwise, services may be interrupted.

Whether the standby firewall forwards traffic in hot standby deployment
The standby device does not forward service traffic. However, the device properly forwards traffic sent to it, such as the ICMP packet for pinging the device interface IP address. Therefore, you can view traffic on the standby device.

Do WLAN devices support hot-standby backup
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.
