Exam 200-301 topic 1 question 299 discussion

Mode Passive: The mode places a port into a passive negotiating state, in which the port RESPONDS to LACP packets that it receives, but DOES NOT initiate protocol negotiation.

This questions say that "SW A RESPOND, BUT NOT START LACP COMMUNICATION". Ask that "WHICH LACP MODE DOESN`T START COMMUNICATION?" LACP modes -> Active/Passive. Active -> Start Communication Passive -> Doesn`t start Communication. Correct Answer is "D".

Answer A is for Static EtherChannel. Meanwhile, the commands for answer D is not in order, at least not in a way that's acceptable in packet tracer. If they were, then , D would work. S1(config)#int ran g0/1-2 S1(config-if-range)#int port S1(config-if-range)#int port-channel 1 S1(config-if)#channel-g S1(config-if)#channel-gr S1(config-if)#? arp Set arp type (arpa, probe, snap) or timeout bandwidth Set bandwidth informational parameter cdp Global CDP configuration subcommands delay Specify interface throughput delay description Interface specific description duplex Configure duplex operation. exit Exit from interface configuration mode hold-queue Set hold queue depth S1(config-if)#end S1# %SYS-5-CONFIG_I: Configured from console by console

D is correct

It´s D

beacuse of LACP and only respond so it's passive

i can understand why this is passive but what is this port channel 1?

Like the guys said, the correct answer is D. In the "On mode" LACP packets are NOT EXCHANGED, so there is NO LACP COMMUNICATION. This mode forces the interface to channel without LACP.

if you can understand that LACP is Active/ passive we can move forward nicely. A is completely wrong and must not be compared with. thank you

This has to be D

LACP is the give away price for D

Answer D

All answers are wrong since: it's not A because Static etherchannel uses "on mode". However, the command on D should be: interface range gigabitethernet0/0/0-15 channel-group 1 mode passive

" respond to but not initiate LACP communication" Should be passive mode interface of LACP which is just waiting for LACP communication. Answer is D.

A is correct....D states LACP

A is correct, Invalid command for D.

MODE ON: Mode that forces the LAN port to channel unconditionally. In the on mode, a usable EtherChannel exists only when a LAN port group in the on mode is connected to another LAN port group in the on mode. Because ports configured in the on mode do not negotiate, there is no negotiation traffic between the ports. You cannot configure the on mode with an EtherChannel protocol. If one end uses the on mode, the other end must also. MODE PASSIVE: LACP mode that places a port into a passive negotiating state, in which the port responds to LACP packets it receives but does not initiate LACP negotiation. (Default)
