Hi guys,can anybody give me a help?
According to the cisco books,the silent submode of PAgP is used to form an EhterChannel with a device such as a file server or a network analyzer.
So,if one endpoint of a link is cisco switch and is configured in "auto silent" mode while the other endpoint is a "silent partner" such as a network
analyzer, the switch will form a channel after 15 seconds without any negotiation.
So I think that if tow cisco switches at both ends of a link are configured in "auto silent" modes can form a EtherChannel, because both endpoints are
in "silent" submode,however,the result of the test is not like what I think.
Can anybody tell me what a "silent partner" is and what is the difference between "switch to switch(both are auto silent mode)" and "swith to silent partner"?
I hope this link to CCNP Practical studies switching will help clarify the matters to you:
