我想知道的是答案B A hub is connected directly to FastEthernet0/5.
是從0010.7b00.1540 Dynamic 2 FastEthernet0/5
跟 0010.7b00.1545 Dynamic 2 FastEthernet0/5
這裡所知道的,但我想問的是如何能確認它接的是hub?因為它題目下方的解說只有這段
但沒提到關鍵點
From the information given by show cdp neighbors we find that there is no
Fa0/5 in CDP
neighbor. However, F0/5 corresponds to two MAC addresses in the same VLAN.
Thus we
know that Fa0/5 is connected to a Hub.
想請熟識這方面的板上高手告知小弟,感謝
