Adding a WAC Group
Context
If standalone WACs are used and deployed in hot standby (HSB) mode, member devices must be added to the site before they are managed by iMaster NCE-Campus (refer to Adding Devices for more information). In addition, you need to configure HSB using commands in advance. After the configuration is complete, add a WAC group to the site on iMaster NCE-Campus.
When deploying VRRP HSB on standalone WACs, use the direct link between the master and backup WACs as the link for VRRP packet forwarding.

Configuring HSB
Figure 4-4 shows the data for configuring two standalone WACs to work in HSB mode.
- Configure VLANs and interface addresses for connecting WAC 1 and WAC 2 to the core switch.
