How Dynamic Port Assignment Works

Initially each port is assigned to the default Group. In this example, all three ports have work-
stations that belong to three different
ports start out in the default Group.
Group Mobility examines traffic coming from OmniS/R ports. Three mobile groups are
defined on the switch and each uses a different IP policy. Traffic that matches IP policies for a
Group will trigger the movement of the port to the matching Group.
Group 1
Default Group
Port 1
130.0.0.1
As soon as the workstations start transmitting traffic, Group Mobility checks the source subnet
of the frames and looks for a match with any configured IP policies. If a match is found—and
in this example all three ports can be matched with a corresponding Group—the port is
moved to the matching Group.
Devices matching a policy trigger the assignment of a port to a mobile group. Therefore, the
device is moved to the mobile group at the same time as the port to which it is attached. If
more than one device comes in on a port, then that port can belong to more than one mobile
group. Similarly, if a device transmits more than one protocol—such as IP and IPX—then the
port to which it is attached can belong to more than one mobile group.
