Silent Mode
If your switch is connected to a partner that is PAgP-capable, you can configure the switch port for nonsilent
operation by using the non-silent keyword. If you do not specify non-silent with the auto or desirable mode,
silent mode is assumed.
Use the silent mode when the switch is connected to a device that is not PAgP-capable and seldom, if ever,
sends packets. An example of a silent partner is a file server or a packet analyzer that is not generating traffic.
In this case, running PAgP on a physical port connected to a silent partner prevents that switch port from ever
becoming operational. However, the silent setting allows PAgP to operate, to attach the port to a channel
group, and to use the port for transmission.

PAgP Learn Method and Priority
Network devices are classified as PAgP physical learners or aggregate-port learners. A device is a physical
learner if it learns addresses by physical ports and directs transmissions based on that knowledge. A device
