EtherChannel Questions 3

September 12th, 2017 in SWITCH 300-115 Go to comments

Question 1


From the outputs of the “show etherchannel summary” commands we learn that Switch1 is configuring EtherChannel with LACP while Switch2 is configuring with EtherChannel “on” mode -> the EtherChannel bundle does not go up.

Question 2

Question 3

Question 4

Question 5

Question 6

Question 7

Question 8

Question 9


By default, when an LACP channel is configured, the LACP channel mode is passive.

Question 10


From the output above, we see the “Protocol” field is empty (with a “-” sign). Therefore we can conclude it does not run any EtherChannel protocol (mode “on”). This EtherChannel is up with “(SU)” keywords (“S” means “Layer 2” and “U” means “up”) -> This is an Layer 2 EtherChannel mode “on”.

    Question 2
    There was an EtherChannel configured and one of the port was used as SPAN destination. What will be the result?
    A. the EtherChannel will not be operational because the port cannot be used as SPAN destination B. EtherChannel will discard the port used C. the EtherChannel will shutdown

    Answer A

    Can You Configure SPAN on an EtherChannel Port?

    An EtherChannel does not form if one of the ports in the bundle is a SPAN destination port. If you try to configure SPAN in this situation, the switch tells you:
    Channel port cannot be a Monitor Destination Port
    Failed to configure span feature
    You can use a port in an EtherChannel bundle as a SPAN source port.

    Question 2
    I am confused with this.


    Characteristics of Destination Port:
    A destination port can be a physical port that is assigned to an EtherChannel group, even if the EtherChannel group has been specified as a SPAN source. The port is removed from the group while it is configured as a SPAN destination port.

    So the answer is B?
