Understanding Port Groups
Ports on virtual and physical devices regulate data-packet traffic to both ensure security and a guaranteed rate of packet flow, and prevent unsolicited traffic. Since configuring each port individually would be tedious, especially if the ports are configured with the same settings, port groups enable configuration of multiple ports simultaneously. First you create the port group (see Creating and Managing Port Groups, and then you can assign a Port profile to the Port Group—see Assigning and Unassigning Port Profiles from Interfaces.
In the case of wireless ports in a group, you can assign a VLAN profile to the port group—see Assigning a VLAN Profile to Devices or Ports.
The ports in a port group can be located on any of your switches or controllers and can include ports from different devices and from different series. Group port configuration has precedence over any individual port configuration.
