PAgP silent mode

Hello!

Can anyone explain me what is PAgP silent mode used for?

According to Cisco docs it is used when switch is connected to PAgP-incapable device.

Then why use PAgP at all? I believe in such situation we should use the mode "on"

Am I wrong?

Thank you!

Re: PAgP silent mode

See if this clarifies the issue - from http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/12111yj4/lrescg/swethchl.htm#73954

"The silent mode is used 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 interface to a channel group, and to use the interface for

transmission."
