LACP with STP Sim

You certainly have some agreeable opinions and views. http://www.certprepare.com provides a fresh look at the subject.

@all
what is the exact configuration that will come in the exam 4 this lab?????????????????

@ Saiqa
Use my answer on page # 8

I did the exam today , there is three labs : LAPC, MPLS, AAA same question only change some IPs . Also, one Q for wirelss and two for VoIP and the remaining from VLA , VTP , GLBP, HSRP , VRRP.

I’ve completed switching exam today

3 LABS + 3 Dragdrop + 1 HSRP hotspot + etc…..

Hi all,
I wrote SWITCH today, and passed 825/1000
They’ve implemented a pruning task to the LACP simulation, otherwise, same old.

Cheers

Hi Alex,
I`m having the exam Monday, What was the pruning task?
just enabling at the vtp server?

Thanks in advanced.

guys which LACP Question will appear in exam now a days? the Vaio’s lab which he solve or toy_man123 lab ?

This configuration doesn’t look right to me. Why are we creating access ports on Switch B. Anyone got this SIM correct? What is the correct configuration? Any help will be appreciated. Thanks in advance.

@paul
because switch B is a access switch and switch A is a distributed switch in actual switch exam

see the correct diagram..http://www.ciscobibles.com/archives/3604.html
for any other query contact me @ tokle.sumit@gmail.com

@Spy
are you shure the configuration provided by you is absolutely right????????????????????

@ saiga
101% i am sure….around 50 people contact me through mail….& all of them say thank you spy…your configuration was perfect… although it has some ambiguity but it works for exam….

When I configure the interface fa0/3 -4 and add the configurartion, do I need to add the same configuration on int port-channel 1 or just do a no shut?

Hai,

I passed exam today with 814 but i lost this question
They have made many change on this question
1. switch A & B are swapped
2.interface range command didnt work for me that really sucks
3. manual pruning to be enabled

Its now my turn to pay and share my switch exam. .I used the below link only and the labs in this site (certprepare) to study and pass with 9xx/1000 rating.

http://www.examcollection.com/cisco/Cisco.ActualTest.642-813.v2011-11-11.by.nonentity.407q.vce.file.html

The MC answers are scrambled in the real exam and all came from the above dump.

In LACP w/ STP Sim, check carefully ports fa0/3 & fa0/4 on SWA & SWB because they are assigned as access and in a different vlan. Dexter, VAIO and Spy’s configuration are almost similar. .practice makes perfect ! ! !

Thanks a lot certprepare and nonentity ! ! !

What seems to be incorrect to me is a configuration with “switch trunk vlan native 99″ and missisng this vlan in allowed vlans in trunk, this wont work normally.

@ spy
@all

there is difference in the answers of p4s dumps and nonentity vc file??? what should i do please tell me.. i have exam after 11 hour please reply fast

@Anonymous do u remember which question Answers are scrambled…or those Questions where we choose THREE CORRECT Answers..

I has completed my exam yeserday…
Got lacp-stp,mls-eigrp,aaadot1x and hsrp hotspot
but be careful with with lacp-stp and practice it very well
dot1x—– follow the same config given in certprepare

in the cisco official guide, they refer to a ‘manual prune’ of vlans as the [#switchport trunk allowed vlan] command

do you think they’re referring to this in the exam, or are they including VTP in this and therefore we have to enable vtp over the switches? put them in vtp domains etc etc?

@spy and @all after completing lab any one tried which are all the ports in native trunk ?

is any one observe this
Distributed switch Vlan 98 “Parking” 99 “TrunkNative” and vlan 11-13 “AMD,BMD,CMD” created.
all switchport access vlan 98

In all simulation “copy run stat or Wr or copy running-config starting-config” it wont work

Blindly creating vlan no helps:

SwitchA(config)#int fa 0/21
SwitchA(config-if)#switchport mode access
SwitchA(config-if)#switchport access vlan 21
SwitchA(config-if)#spanning-tree protfast

SwitchA(config)#int fa 0/22
SwitchA(config-if)#switchport mode access
SwitchA(config-if)#switchport access vlan 22
SwitchA(config-if)#spanning-tree protfast

SwitchA(config)#int fa 0/23
SwitchA(config-if)#switchport mode access
SwitchA(config-if)#switchport access vlan 23
SwitchA(config-if)#spanning-tree protfast

typo SwitchA(config-if)#spanning-tree portfast

hi all, can someone pls tell me why this command is added on the distribution switch?
#(config) spanning-tree vlan 11-13, 21-23 root primary
– why is it vlan 11-13? is it bcoz it’s configured on the switch? what about vlan’s 1, 98-99? should i also include that?

- your feedback is highly appreciated — THANKS!

@subghat. .all answers in nonentity dumps were scrambled in the real exam (if it is (a) in the dump, it is in (c) of the real exam). . do not memorize how they are arranged and read the answers carefully. . . good luck ! ! !

because switch B is a access switch and switch A is a distributed switch in actual switch exam

see the correct diagram..http://www.ciscobibles.com/archives/3604.html

You certainly have some agreeable opinions and views. http://bestipshot.blogspot.com provides a fresh look at the subject.

Passed the exam. All questions appeared from NonEntity dump (Examcollection.com).

Three sims appeared in the exam(Thanks to Certprepare.com):
1. MLS with EIGRP
2. AAAdot1x
3. LACP with STP.

HSRP HotSpot Question
Drap & Drop SNMP Question

@spy (or anyone else)

Aren’t any configurations you make on the port-channel automatically configured on the ports in the port-channel? e.g. if you do “switchport trunk native vlan 99″ on port-channel 1, aren’t the interfaces (fa0/3 – 4 in this case) automatically configured as if you had put the same command on the interface range?

Maybe I’ve picked something up wrong but, if I’m right, it would save some of your configuration.

I’m sitting in 12 hours so if someone could let me know whether I’m right or whether I am totally off my head, it would be appreciated.

Passes switch today , now i’m CCNP

Guys refer to spy configurations as it meet the new requirements

Going to sit right now. I’ll let you know if there are any changes. Expecting to fail – 2 days study is not really enough, doh!

Please I want to understand if this names for this Vlan are given in the real exams or I can create the name of the Vlan my self bcus I know Vlan 21-23 are given thanks for your contributions.

vlan 98
name parking
vlan 11
name AMD
vlan 12
name BMD
vlan 13
name CMD

@ all …
please refer my answer……….as there is little glitch present in this sim ..so i have added native vlan configuration….

for little doubt use tokle.sumit@gmail.com

Please give me a complete configuration according to LACP exam.
and which one is correct configuration in LACP exam on switch a n b.
Switchport trunk allow vlan 1,11-13,21-23,99 is correct or
Switchport trunk allow vlan 1,11-13,21-23 is correct or
Switchport trunk allow vlan 1,11-13,21-23,99 is correct or
Switchport trunk allow vlan 1,21-23,99 is correct or
Switchport trunk allow vlan 1,21-23 is correct and used in LACP exam.

Just passed the Switch exams…..thanks for the contribution from this site, i had 40 question 3 lab sims, AAA, lacp stp and mls Eigrp sim.

@ Zuela

That’s exactly what I got today. Flew though it. All Qs from nonentity v4 vce and sims from here. Thanks to everyone who contributes to this site and examcollection. TShoot next. As for my last question on here – i was wrong in my assumption (well it didn’t work in the exam, dunno about real life).

this is complete question you may find in your exam…

You work for SWITCH.com. They have just added a new switch (SwitchB) to the existing network as shown in the topology diagram.

RouterA is currently configured correctly and is providing the routing function for devices on SwitchA and SwitchB. SwitchA is currently configured correctly, but will need to be modified to support the addition of SwitchB. SwitchB has a minimal configuration. You have been tasked with competing the needed configuring of SwitchA and SwitchB. SwitchA and SwitchB use Cisco as the enable password.

Configuration Requirements for SwitchA

· The VTP and STP configuration modes on SwitchA should not be modified.

• SwitchA needs to be the root switch for vlans 11, 12, 13, 21, 22 and 23. All other vlans should be left are their default values.

Configuration Requirements for SwitchB

• Vlan 21

o Name: Marketing

o will support two servers attached to fa0/9 and fa0/10

• Vlan 22

o Name: Sales

o will support two servers attached to fa0/13 and fa0/14

• Vlan 23

o Name: Engineering

o will support two servers attached to fa0/15 and fa0/16

• Access ports that connect to server should transition immediately to forwarding state upon detecting the connection of a device.

• SwitchB VTP mode needs to be the same as SwitchA.

• SwitchB must operate in the same spanning tree mode as SwitchA

• No routing is to be configured on SwitchB

• Only the SVI vlan 1 is to be configured and it is to use address 192.168.1.11/24

Inter-switch Connectivity Configuration Requirements

• For operational and security reasons trunking should be unconditional and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk link.

• The two trunks between SwitchA and SwitchB need to be configured in a mode that allows for the maximum use of their bandwidth for all vlans. This mode should be done with a non-proprietary protocol, with SwitchA controlling activation.

• Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk link.

can somebody confirm which command to use to check the spanning-tree mode on a switch?
is it — show spanning-tree or show spanning-tree summary ???? please advice…

Hello spy ,

in LACP lab how to manual pruning on this trunk link.

Hello spy
in LACP lab root primary command is used or priority comand in exam.

in LACP lab trunk encapsulation dot1Q is working and used in exam or not

@Anonymous – you need to use the ‘show spanning-tree summary’ command. Have you got packet tracer? Try the lab out – you really need to practise this to stand having a chance anyway.

Hi,

i just need to know one thing that shall we need to create VLAN 21,22 and 23 on Switch A or they will be present already ?

i don’t have time to see all the comment if you have any regarding this sim then use my answer which i have uploaded on page no 8 else you can send me mail on tokle.sumit@gmail.com

Dears,

Please help me on LACp Lab i tried the exam today but with no luck aslo the command Spanning tree vlan is not working also i can’t create Vtp Mode .

Hi,

spanning-tree vlan 1,21-23 in interface 0/3-4 or in

port-channel 1 configurtion???

CCNP FAIL, if You are not sure whether vlans exist or not, use “show vlan brief” and check…

Guys ,passed the switching paper few hrs back .You can stick on nonentity dumps..still valid and seems some correction required on answers..but damn sure ..can pass
Thanks to all related teams and best of luck for appearing guys..

@Noruy

Finally which 1 is correct answer for Question 1 in P4S Page 2
Thanks to all.
http://karachi-fm-live.blogspot.com

does anybody have lab simulations ? please send an email to the below address. thanks.
p3anfa@gmail.com

“Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk link.”

Couple people mention this is new. Your VLAN Allowed lists on both sides of the link is the same this as “manual pruning” – correct? Don’t think this is anything different.

Dear All,

First:- This command is not working and why we need it.
********switchport trunk encapsulation dot1q**********
spanning-tree allowed vlans 1,21-23
no shut

Second:- switchport trunk native vlan 99 **** why we need and i will do at switch B then we need it also at switch A.
please explain. Thanks.

did the exam several things in this question.
Is was necessary that vtp and stp mode is the same
need to create vlans with apropriate names
need to set up switch b for root in several vlans

Can some one explan the answer of last two comments and also add
Switch A ( Distributed Switch) will be Active or Switch B ( Access Switch) will be Acctive.
Most peolpe did not know. Some are saying B will be active and A will be Passive.

@Annos
http://where-is-cappadocia.blogspot.com
It need at boths, because if LACP is down or any link is down ,So with one link it will also will be same, like native VLAN and Trunk will need to anable in both interface.

spanning-tree vlan 1,21-23 in interface 0/3-4 or in
port-channel 1 configurtion???

Mr. Spy have told before please check it. It is correct may be

Access ports that connect to server should transition immediately to forwarding state upon detecting the connection of a device.

• SwitchB VTP mode needs to be the same as SwitchA.

• SwitchB must operate in the same spanning tree mode as SwitchA

• No routing is to be configured on SwitchB

• Only the SVI vlan 1 is to be configured and it is to use address 192.168.1.11/24

Inter-switch Connectivity Configuration Requirements

• For operational and security reasons trunking should be unconditional and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk link.

• The two trunks between SwitchA and SwitchB need to be configured in a mode that allows for the maximum use of their bandwidth for all vlans. This mode should be done with a non-proprietary protocol, with SwitchA controlling activation.

• Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk link.

To make Switch B the root, can the command on Switch B :-
spanning-tree vlan 1,21-23 root primary
not do the trick?

There are variations in the Lab example of LACP with STP SIM, can anyone contribute the excat configuration for this and if possible can anyone have the complete questions atleast on the same lab???please help need to give exam this saturday..

There are no latest updates on LAB of LACP with STP SIM…atleast the complete question.

do we need to configure ip default gateway ( Ip address of router ) on any of the switch ?

Yes we do need to configure default gateway on the switch. We need to check the configuration of both the switches and configure the default gateway wherever required.

tks certprepare, i’m pass 642-813 – 934 point, with this lab, i’m follow instruction of genius_matlas, i’m try to pass TSHOOT in near day. tks all you much

I have come across this simulation
spanning-tree allowed vlans 1,21-23 command is not correct as it doesn’t accept

Switchport trunk allowed Vlan command works , however I never made this simulation work because of native Vlan mismatch although I tried several times changing the Native Vlan on both switches to match same

I see this image has been blatantly stolen and stuck in Pass4Sure.
You can even see their poor attempt at shopping out the logo
P4S code update 8.1

http://www.drivesaholden.com/p4s.PNG

Helps if I leave a name I guess.

On the real exam, the set-up of the switch was interchanged.

SwB SwA Router

I have answered this one, although some points were deducted.
*Note: Do not change VTP and STP on Switch A.

So, you should change the priority on SwB and put on the highest possible value which is 61440.
This is to make the SwA the root bridge what ever value it has.

By the way, the question requires that SwA should be the root brdige for vlan 11,12,13,21,22 and 23. Other VLAN should be default.

Other requirements not mentioned in this Sim.

*Swich B STP mode should be the same with Switch A.

SwA is on “rapid pvst” while SwB is only on pvst.

*Switch B VTP set-up should be the same with SwS.

SwA is set to VTP transparent while SwB is set as Server.
Just change SwB VTP mode to Transparent.

Also, another advice. remove “switchport access vlan 98″ on SwA fa0/3 – 4 to avoid VLANs mismatch.
you may add “switchport trunk native vlan 1″ to avoid native vlan mismatch. (SwB’s native vlan is on default which is vlan 1)

spanning-tree allowed vlans will not work.

Use “switchport trunk allowed vlan 11-13,21-23 (on the question, even 11-13 is also need to be allowed, when you do the manual pruning).

Hope this helps.

Got a score of 967/1000. Yay!
Goodluck guys.

Just passed this one (934/1000), was my first question.

As above is almost correct.

One thing I forgot, Trunks are NOT allowed to negotiate.. I forgot the
“swtichport trunk nonegotiate” command and lost a few points there

Dont set the native vlan to 1 either, the requirement states that vlan 1 needs to be tagged (not encapsulated) so use 802.1q and change the native vlan to 99 (there is a vlan on Switch A for this)
As VTP is transparent the vlans are not re-created on the other switch.
For it to become a root for those vlans as well add each vlan to Switch A as well as swtich B

There should be no need to remove the vlan 98 (this is for unused ports)

passed the exam today with 901. thanks to certprepare

there is a bug on the lacp sim.. i got stp as pvrst+.. but i was rcving stp error messages with inconsistent port types. i configured the same way as it is supposed to be

and again could not confirm any parameters the port channel could just add native vlan and allowed vlan..

not sure if lab was correct..

i was not able to ping the router ip.

@ Altreidae:

How do you know you “lost a few points there “? I never get a summary of which questions are correct or wrong … Or did you get that om the end of the exam ? That’s new for me…
