This task requires you to use the CLI of Sw-AC3 to answer multiple-choice question below. This
does not require any configuration. Refer the Explanation to see all the configuration details.
Out of which ports will a frame be forwarded that has source mac-address 0010.5a0c.fd86 and
destination mac-address 000a.8a47.e612? (Choose three)
A.
Fa0/8
B.
Fa0/3
C.
Fa0/1
D.
Fa0/12
Explanation:
First we check to see which ports the source mac-address and the destination mac-address
belong to by using show mac-address-table command.
We notice that the source mac-address 0010.5a0c.fd86 is listed in the table and it belongs to Vlan
33 but we can’t find the destination mac-address 000a.8a47.e612 in this table. In this case, the
switch will flood to all ports of Vlan 33 and flood to all the trunk links, except the port it received
this frame (port Fa0/6). Therefore from the output above, we can figure out it will flood this frame
to Fa0/1, Fa0/3 and Fa0/12.
Please notice that the “show mac-address-table” command just lists information that was learned
by the switch, it means that there can be other ports besides Fa0/1, Fa0/3 and Fa0/12 belong to
Vlan 33. You can use the show vlan command to see which ports belong to vlan 33
And we found other ports which belong to vlan 33, they are Fa0/2, Fa0/5 and Fa0/7. Our switch
will flood the frame to these ports, too.
And we can check which trunk ports will receive this frame by the show interface trunk command
