Question
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.
Configuration Requirements for SwitchB
Vlan 21, Name: Marketing, will support two servers attached to fa0/9 and fa0/10
Vlan 22, Name: Sales, will support two servers attached to fa0/13 and fa0/14
Vlan 23, Name: Engineering, 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.

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

LACP with STP Sim

We post the initial configuration of Sw-A & Sw-B here for your reference, you can try solving this sim by yourself before reading the asnwers below: Initial Configuration (useless lines have been removed) SwA: hostname Sw-A ! vtp mode transparent ! spanning-tree mode rapid-pvst ! vlan 98 ! vlan 99 name TrunkNative ! interface FastEthernet0/ switchport access vlan 98 switchport mode access ! interface FastEthernet0/ switchport access vlan 98 switchport mode access ! interface FastEthernet0/ switchport access vlan 98 switchport mode access ! interface Vlan no ip address shutdown ! end Sw-B: hostname Sw-B ! vtp mode server ! spanning-tree mode pvst ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface FastEthernet0/ ! interface Vlan no ip address shutdown ! ip default-gateway 192.168.1. ! end From http://web.archive.org/web/20150711171456/http://www.certprepare.com/lacp-with-stp-sim

Initial configuration of 2 switches

Tuesday, February 21, 2017 11:41 AM

SW-B (far from router) name Marketing exit vlan 21 name Sales exit vlan 22 name Engineering exit vlan 23 name TrunkNative exit vlan 99 switchport mode access switchport access vlan 21 spanning-tree portfast no shutdown exit interface range fa0/9 – 10 switchport mode access switchport access vlan 22 spanning-tree portfast no shutdown exit interface range fa0/13 – 14 switchport mode access switchport access vlan 23 spanning-tree portfast no shutdown exit interface range fa0/15 – 16 vtp mode transparent spanning-tree mode rapid-pvst ip default-gateway 192.168.1. ip address 192.168.1.11 255.255.255. no shutdown Exit interface vlan 1 switchport trunk encapsulation dot1q Switchport mode trunk Switchport trunk native vlan 99 switchport trunk allowed vlan 1,21- 23 channel-group 1 mode passive channel-protocol lacp no shutdown Exit interface range fa0/3 – 4 switchport trunk encapsulation dot1q switchport mode trunk switchport trunk native vlan 99 switchport trunk allowed vlan 1,21- 23 no shut interface port-channel 1 The switch maybe 3650 so might need encapsulation (open standard) Make two ports connecting to sw_A as trunks and native vlan 99 or same as A Most critical commands Needs to give on interface in exam/packettracer Then for pruning needs to tell the vlan Passive command because Sw_A will do the activation for etherchannel lacp = industry standard protocol Create the Required Vlans with Names Tell the switch which ports belongs to which vlans. Assign them as a access ports Make them as portfast to bring these ports up in short span of Time Should be same as on Switch A

It was on certprepare but no need for this command

Create SVI port Configure Etherchannel for maximum speed (part of the question) same configs which we did on physical ports will do here.

**If you are able to ping router from Switch B And in show etherchannel summary showing PU (P) (P) then it means your lab is correct !!!*****

  • 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. SW-A(config)#interface range fa0/3 – 4 SW-A(config-if)#no switchport mode access SW-A(config-if)#no switchport access vlan 99 Note: Two above commands must be deleted first to form a trunking link. Although the first requirement asks us to configure trunking but we can ignore this task because we only need to configure trunking under their Port-channel (in the next task)
    • 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: SW-A(config)#interface range fa0/3 – 4 SW-A(config-if)#channel-group 1 mode active SW-A(config-if)#channel-protocol lacp SW-A(config-if)#no shutdown
    • Trunking should be unconditional and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk link: SW-A(config-if)#interface port-channel 1 SW-A(config-if)#switchport mode trunk SW-A(config-if)#switchport trunk native vlan 99 //this command will prevent the “Native VLAN mismatched” error on both switches SW-A(config-if)#no shut ————————————— SW-B(config)#interface range fa0/3 – 4 SW-B(config-if)#channel-group 1 mode passive SW-B(config-if)#channel-protocol lacp SW-B(config-if)#no shutdown SW-B(config-if)#interface port-channel 1 SW-B(config-if)#switchport trunk encapsulation dot1q SW-B(config-if)#switchport mode trunk SW-B(config-if)#switchport trunk native vlan 99 //this command will prevent the “Native VLAN mismatched” error on both switches SW-B(config-if)#no shut
  • Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk link. SW-A(config)#interface port-channel 1 SW-A(config-if)#switchport trunk allowed vlan 1,21- 23 ————————————— SW-B(config)#interface port-channel 1 SW-B(config-if)#switchport trunk allowed vlan 1,21- 23 Note: When configure this command under Port-channel 1, the same command will be applied to physical member interfaces (of port-channel 1) so you don’t need to type them under physical member interfaces again.

Inter-switch Connectivity Configuration Requirements:

  • You should check the initial status of both switches with these commands: show vtp status (transparent mode on switchA and we have to set the same mode on switchB), show spanning-tree [summary] (rapid-pvst mode on switchA and we have to set the same mode on switchB), show vlan (check the native vlan and the existence of vlan99), show etherchannel 1 port-channel and show ip int brief (check if Port-channel 1 has been created and make sure it is up), show run (to check everything again).
  • When using “int range f0/x – y” command hit space bar before and after “-” otherwise the simulator does not accept it.
  • You must create vlan 99 for the switchB. SwitchA already have vlan 99 configured.
  • At the end, you can try to ping from SwitchB to RouterA (you can get the IP on RouterA via the show cdp neighbors detail on SwitchA), not sure if it can ping or not. If not, you can use the “ip default-gateway 192.168.1.1″ on SwitchB.
  • The name of SwitchA and SwitchB can be swapped or changed so be careful to put your configuration into appropriate switch. We hope with this information our candidates can find the best solution in the exam. If you learn anything new about this sim please share with us!
