lacp+stp+sim (updated p4s)

A SPECIAL THANKS TO THE FOLLOWING PEOPLE FOR ALL THEIR HELP & SUPPORT: 1) ARSALAN “KaimKhani”

2) MR DEXTER FOR THE ORIGINAL CONCEPT OF LACP

3) CCNP_SWITCH_JUST PASSED FOR HIS LAST MINUTE HELP YEST SINCE I WAS DUE TO SIT TODAY

4) ALL THE MEMBERS OF CERTPREPARE FORUM FOR THEIR CONTINOUS SUPPORT & FEEDBACK…..I EXPECT THE SAME IN TSHOOT EXAM

NOTE: PLZ DON’T EDIT/MODIFY THE CONTENTS OF THIS CONFIGURATION SINCE IT HAS BEEN PUT TOGETHER WHILE GOING THROUGH COUNTLESS BLOGS/POSTS & WEBSITES

JUST HAD MY EXAM TODAY….PASSED WITH 9** SCORED 100,100 & 97 RESPECTIVELY IN ALL 3 SIMS….SO ALL THE CONFIG THAT HAS BEEN MENTIONED BELOW IS 100% TESTED & VERIFIED & THE CONIG BELOW IS UP-T0-DATE WITH ALL THE NECESSARY STEPS….AS FAR AS THE PRUNING FUNCTION GOES THAN IT CANNOT BE CONFIGURED ON EITHER SWITCHES

FOR ANY OTHER QUERIES IF U STILL HAVE AFTER GOING THROUGH THE CONFIGS HERE THEN EMAIL ME @ [email protected], but only SERIOUS QUERIES no silly questions

mailto:[email protected]

PLZ READ THE REQUIREMENT CAREFULLY SINCE U WILL FIND MORE THAN 50% OF THE REQUIREMENT FOR THIS SIM IN HERE…..I DID EDITED THE PORTION BELOW BUT U WILL FIND THE

COMPLETE LABSIM OUTPUT IN P4S PDF FILES V6.8 (TOPIC 6 QUESTION NO 8)

SwitchA#show vtp status —> Write down the VTP mode (Is in

transparent mode needs to same on swB)

SwitchA#show spanning-tree summary or show run—> Write down

the STP mode (is set to rapid-pvst needs to be same on swB)

SwitchA#show vlan —> (Check whats the native VLAN-can be

identified by the name “TrunkNative”, VLAN 99)

(NEED to create vlan 21-23)

___________________________________________________________________________

Switch A (DISTRIBUTION SWITCH::need to configure trunk , vlans & ether channel mode ACTIVE)

SwitchA(config)#vlan 21

SwitchA(config-vlan)#name Marketing exit


SwitchA(config-vlan)#name Sales exit


SwitchA(config-vlan)#name Engineering exit

SwitchA(config)#spanning-tree vlan 11-13,21-23 root primary (assigning swA as root

switch for respective vlans as required::vlan 11-13 already there)

***This completes VLAN configuration***

SwitchA(config)#int range fa0/3 – 4 –> Make sure you put a space between “3 – 4″ for it

to accept the command

SwitchA(config-int-range)#no switchport access vlan 98 (need to remove vlan98)

SwitchA(config-int-range)#switchport trunk encapsulation dot1q works on swA

SwitchA(config-int-range)#switchport mode trunk not supported on swA:rest works

SwitchA(config-int-range)#switchport trunk native vlan 99

SwitchA(config-int-range)#switchport trunk allowed vlan 1,21-23 (tagging vlans)

SwitchA(config-int-range)#channel-protocol lacp

SwitchA(config-int-range)#channel-group 1 mode active –> Distribution switch

needs to be ACTIVE

SwitchA(config-int-range)#exit

SwitchA(config-if)#int port-channel 1

SwitchA(config-if)#no shutdown

SwitchA(config-if)#exit

# copy running-config startup-config

***This complete’s Etherchannel configuration***

Check the all the interfaces especially Fast Ethernet 0/3 and 0/4 cause those interfaces were already assigned to a “Parking” vlan98, so we need to remove it from that vlan because we later

we will be assigning them to trunk port

Move on to SwitchB (ACCESS SWITCH-need to configure vtp/stp mode, trunk+access ports, svi & ether channel mode PASSIVE)

SwitchB#show vlan —> check if any of the required VLAN’s are

pre-configured (Need to configure 11-13,21-23 & 98-99)

SwitchB#show vtp status —> Check VTP mode of switchB (SwitchB

is in Server mode, need to change to Transparent)

SwitchB#show spanning-tree summary or show running-config

(check spanning tree mode change to rapid-pvst)

********************************************************************************** SwitchB(config)#vtp mode transparent (since swA is also in the same mode) SwitchB(config)#spanning-tree mode rapid-pvst (switchA is in rapid-pvst mode)

***This complete’s STP and VTP configuration***

***This completes VLAN configuration***

SwitchB(config)#int range fa 0/9 – 10

SwitchB(config-int-range)#switchport mode access

SwitchB(config-int-range)#switchport access vlan 21

SwitchB(config-int-range)#spanning-tree portfast

SwitchB(config)#exit




SwitchB(config-int-range)# spanning-tree portfast

SwitchB(config)#no shutdown

SwitchB(config)#exit




SwitchB(config-int-range)# spanning-tree portfast


SwitchB(config)#exit In my case SVI was pre-configured….it can be checked by “show ip int brief” on swB vlan 1 was ip

assigned & state was UP SwitchB(config-if)#ip default-gateway 192.1.68.1.1 (might not be needed but type it

anyway-router’s ip address)

***This completes access ports configuration***

SwitchB(config)#int range fa0/3 – 4 (shut by default in exam-configuring as trunks)

SwitchB(config-int-range)#switchport trunk encapsulation dot1q (not working on swB)

SwitchB(config-int-range)#switchport mode trunk works on swB

SwitchB(config-int-range)#switchport trunk native vlan 99

SwitchB(config-int-range)#switchport trunk allowed vlan 1,21-23 (tagging vlans)

SwitchB(config-int-range)#channel-protocol lacp

SwitchB(config-int-range)#channel-group 1 mode passive –> Access switch needs

to be PASSIVE SwitchB(config-int-range)#exit

SwitchB(config-if)#int port-channel 1


exit

***This complete’s Etherchannel configuration***

SwitchB# ping 192.168.1.1

!!!!!

NOTES COURTESY OF CCNP_SWITCH_PASSED:

The Port-channel will be automatically created.. Just go under port-channel int & give “NO SHUT”

command on both Switch A&B.. At next second..

The interfaces fa0/3-4 will be UP..(No need to give “No shut” cmd Under fa0/3-4 interfaces

NOTE: By default switch ports are SHUT so give the no shutdown command under int port-channel 1 in

the end once config is done on both switches….NO VLAN MISMATCH ERRORS THEN!!!!!

1. On Switch A: show cdp neighbor detail –> Get the ip address of router. This is necessary to do a ping

test at the end of the config

2. show vlan

3. show spanning-tree summary

4. show vtp status

5. show ip int brief
