我想知道的是答案B A hub is connected directly to FastEthernet0/5.
是从0010.7b00.1540 Dynamic 2 FastEthernet0/5
跟 0010.7b00.1545 Dynamic 2 FastEthernet0/5
这里所知道的,但我想问的是如何能确认它接的是hub?因为它题目下方的解说只有这段
但没提到关键点
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.
想请熟识这方面的板上高手告知小弟,感谢
