packet is like a shipping container, a frame is the boat on which the shipping
container is loaded.
Gigabit 1 through 4
The Gigabit Ethernet interfaces on XR Series Arrays. XR-4000 Series Arrays have

Gigabit Ethernet

Group
A user group, created to define a set of attributes (such as VLAN, traffic limits,
and Web Page Redirect) and privileges (such as fast roaming) that apply to all
users that are members of the group. This allows a uniform configuration to be
easily applied to multiple user accounts. The attributes that can be configured for
user groups are almost identical to those that can be configured for SSIDs.
