Technical Tip: Interface type which can be member of LACP

When an interface needs to be added as a member of the LACP interface, it should pass the below conditions:

• VLAN, IPSEC, Software Switch, and Wifi SSID interfaces cannot be members of the LACP, and hence these interfaces will not be visible in the interface list.
• LACP interface members can only be Physical interfaces.
• An interface that has references will not be visible in the interface list. To make the interface visible in the interface list, remove all the references of the interface from the configuration.
• The interface should not be configured with any IP; if the interface has an IP set, then it will not be visible in the list. To make the interface visible in the available interface list, remove the IP set from the interface.
