LACP LAB

SWITCH A
(Step-I) Use the command
“show vlan” on switch-A (connected to router)
you will see… Vlan 99—>name NativeTrunking
Vlan 98—->name Parking
(Step-II)… Create vlan 21,22,23 & its name as follow.
SwitchA(config)#vlan 21
SwitchA(config-vlan)#name Marketing
SwitchA(config)#vlan 22
SwitchA(Config-vlan)#name Sales
SwitchA(config)#vlan 23
SwitchA(config-vlan)#name Engineering
(Step-III)
Switch A(config)#int range fa0/3-4
switchA(config-int-range)#shutdown—-> (In the exam it’s already shutdown)
switchA(config-int-range)#no switchport access vlan 98….(*Imp Step)
SwitchA(config-int-range)#switchport trunk encapsulation dot1q—–>( already Config)
SwitchA(config-int-range)#switchport mode trunk
SwitchA(config-int-range)#switchport trunk native vlan 99
SwitchA(config-int-range)#switchport trunk allowed vlan 1,11-13,21-23
SwitchA(config-int-range)#channel-protocol lacp
SwitchA(config-int-range)#channel-group 1 mode active
SwitchA(config-int-range)#exit
SWITCHA(CONFIG)#SPANNING-TREE VLAN 1,11-13,21-23,98-99 ROOT PRIMARY
————————————————————————————————————
SWITCH B
(Step-I)
SwitchB(config)#spanning-tree rapid-pvst
SwitchB(config)#vtp mode transparent
(Step-II)
SwitchB(config)#ip default-gateway 192.168.1.10 (didnt ask in Question but safe side i just configured it)
Create Vlans on switch-B
SwitchB(config)#vlan 21
SwitchB(config-vlan)#name Marketing
SwitchB(config)#vlan 22
SwitchB(Config-vlan)#name Sales
SwitchB(config)#vlan 23
SwitchB(config-vlan)#name Engineering
switchB(Config)#vlan 99
switchB(CONFIG)#name TrunkNative—–>( same as on switch-A)
switchB(Config)#vlan 98
switchB(CONFIG)#name Parking—–>( same as on switch-A)
SwitchB(config)#exit
(Step-III)
SwitchB(config)#int range fa 0/9 – 10
SwitchB(config)#no shutdown
SwitchB(config-int-range)#switchport mode access
SwitchB(config-int-range)#switchport access vlan 21
SwitchB(config-int-range)# spanning-tree portfast
SwitchB(config)#int range fa 0/13 – 14
SwitchB(config)#no shutdown
SwitchB(config-int-range)#switchport mode access
SwitchB(config-int-range)#switchport access vlan 22
SwitchB(config-int-range)# spanning-tree portfast
SwitchB(config)#int range fa 0/15 – 16
SwitchB(config)#no shutdown
SwitchB(config-int-range)#switchport mode access
SwitchB(config-int-range)#switchport access vlan 23
SwitchB(config-int-range)# spanning-tree portfast
SwitchB(config)#int range fa0/3-4
SwitchB(config)#shutdown (In the exam its already shutdown)
SwitchB(config-int-range)#switchport trunk encapsulation dot1q
SwitchB(config-int-range)#switchport mode trunk
SwitchA(config-int-range)#switchport trunk native vlan 99
SwitchB(config-int-range)#switchport trunk allowed vlan 1,11-13,21-23
SwitchB(config-int-range)#channel-protocol lacp
SwitchB(config-int-range)#channel-group 1 mode passive
SwitchB(config-int-range)#exit
(Step-IV). The below step is already Configured..no need to give it.” Show ip int brief” n check vlan 1 is UP & configured with ip address.
SwitchB(config)#int vlan 1
SwitchB(config)#ip address 192.168.1.11 255.255.255.0
SwitchB(config)#no shutdown
(Step-V)…(**Imp Step)
Thats all wid the configuration… 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 )
SwitchA(config)#int port-channel 1
SwitchA(config-int-range)#no shutdown
SwitchA(config-int-range)#exit
SwitchB(config)#int port-channel 1
SwitchB(config-int-range))#no shutdown
SwitchB(config-int-range)#exit
compare the both output from above command the native vlan 99 will be same in both switchs Ping from switch-B to ROUTER by 192.168.1.10

Notes**
Its bit confusing at starting of this lab.. when u read the scenario. But keep Patience take ur time.. copy down all u r steps on the note pad..
