For management purposes, we will use VLAN 99. First, you will create the new VLAN 99 on the switch. Then you will set the IP address of the switch to 172.17.99.11 with a subnet mask of 255.255.255.0 on the internal virtual interface VLAN 99. S1(config-vlan)#vlan 99 S1(config-vlan)#name management S1(config-vlan)#exit S1(config)#interface vlan99 S1(config-if)#ip address 172.17.99.11 255.255.255.0 S1(config-if)#no shutdown Do the same configuration on switches S2 and S3 based on the Addressing Table. A management VLAN is any VLAN that you configure to access the management capabilities of a switch.

6-2-2- Verification Do the verification based on the “CCNA Lab 1-Configuring a Switch Part I”, Detailed Lab Steps, Detailed Lab Steps, Part 2.

6-3: Part 3: Configure Switch and Router to Accept Incoming SSH Connections


Configure all the switchs and router to accept Incoming SSH Connections based on the “CCNA Lab 2-Configuring a Switch Part 2”, Detailed Lab Steps, Part 4.

6-3-2- Verification Do the verification based on the the “CCNA Lab 2-Configuring a Switch Part 2”, Detailed Lab Steps, Part 4.

6-4: Part 4: Configure and Activate Ethernet Interfaces Step 1: Configure the PCs

All three PCs with the IP addresses and default gateways should be configured.

6-5: Part 5: Configure VLANs on the Switch


Step 1: Create VLANs on switch S1

There are four VLANS configured for this lab: VLAN 10 (faculty); VLAN 20 (students); VLAN 30 (guest); and VLAN 99 (management).

S1(config)#vlan 10 S1(config-vlan)#name faculty S1(config-vlan)#vlan 20 S1(config-vlan)#name students S1(config-vlan)#vlan 30 S1(config-vlan)#name guest S1(config-vlan)#end

Step 2: Configure and name VLANs on switches S2 and S3

Create and name VLANs 10, 20, 30, and 99 on S2 and S3 using the commands from Step 1.

Step 3: Assign switch ports to VLANs on S2

Refer to the port assignment table, ports are assigned to VLANs in interface configuration mode. The commands are shown for S2.

S2(config)#interface range fa0/6-10 S2(config-if-range)#switchport access vlan 30 S2(config-if-range)#interface range fa0/11-17 S2(config-if-range)#switchport access vlan 10 S2(config-if-range)#interface range fa0/18-24 S2(config-if-range)#switchport access vlan 20 S2(config-if-range)#end

Step 4: Configure trunking and the native VLAN for the trunking ports on all switches

Use the interface range command in global configuration mode to simplify configuring trunking.

S1(config)#interface range fa0/1-4 S1(config-if-range)#switchport mode trunk S1(config-if-range)#switchport trunk native vlan 99

amir-jafari.com


S1(config-if)#switchport trunk allowed vlan 10,20,30,99 S1(config-if-range)#end S2(config)# interface range fa0/1-4 S2(config-if-range)#switchport mode trunk S2(config-if-range)#switchport trunk native vlan 99 S2(config-if)#switchport trunk allowed vlan 10,20,30,99 S2(config-if-range)#end S3(config)# interface range fa0/1-4 S3(config-if-range)#switchport mode trunk S3(config-if-range)#switchport trunk native vlan 99 S3(config-if)#switchport trunk allowed vlan 10,20,30,99 S3(config-if-range)#end

6-5-2- Verification

Step 1: Verify that the VLANs have been created on S1, S2 and S3 Use the show vlan brief command to verify that the VLANs have been created.

S2#show vlan brief

Step 2: Determine which ports have been added

Use the show vlan id vlan-number command on S2 to see which ports are assigned to VLAN 10.

You can also view VLAN assignment information using the show interfaces interface switchport command.

S2#show vlan id 30 S2#show interfaces fastEthernet 0/6 switchport Step 3: Verify that the trunks have been configured on S1, S2 and S3

Verify that the trunks have been configured with the show interface trunk command.

S1#show interface trunk S1#show interfaces status

Step 4: Verify that the switches can communicate

From S1, ping the management address on both S2 and S3.

S1#ping 172.17.99.12 S1#ping 172.17.99.13

6-6: Part 6: Configuring EtherChannels


Step 1: Configuring Manual EtherChannel

S1(config)#interface range fa0/1-2 S1(config-if-range)# channel-group 1 mode on S1(config)#interface range fa0/3-4 S1(config-if-range)# channel-group 2 mode on S2(config)#interface range fa0/1-2 S2(config-if-range)# channel-group 1 mode on S2(config)#interface range fa0/3-4 S2(config-if-range)# channel-group 2 mode on S3(config)#interface range fa0/1-2 S3(config-if-range)# channel-group 1 mode on S3(config)#interface range fa0/3-4 S3(config-if-range)# channel-group 2 mode on

6-6-2- Verification

Step 1: Verify that the PortChannels have been created on S1, S2 and S3 S1#show etherchannel summary S1#show interfaces status

6-7: Part 7: Configuring Routing to VLANs using 802.1Q on Routers


Step 1: Configure the trunking interface on R1

Router on a Stick (ROAS) uses router VLAN trunking configuration to give the router a logical router interface connected to each VLAN, and therefore each subnet that sits on a separate VLAN.

R1(config)#interface fastethernet 0/1 R1(config-if)#no shutdown R1(config-if)#interface fastethernet 0/1.1 R1(config-subif)#encapsulation dot1q 1 R1(config-subif)#ip address 172.17.1.1 255.255.255.0 R1(config-if)#interface fastethernet 0/1.10 R1(config-subif)#encapsulation dot1q 10 R1(config-subif)#ip address 172.17.10.1 255.255.255.0 R1(config-if)#interface fastethernet 0/1.20 R1(config-subif)#encapsulation dot1q 20 R1(config-subif)#ip address 172.17.20.1 255.255.255.0 R1(config-if)#interface fastethernet 0/1.30 R1(config-subif)#encapsulation dot1q 30 R1(config-subif)#ip address 172.17.30.1 255.255.255.0 R1(config-if)#interface fastethernet 0/1.99 R1(config-subif)#encapsulation dot1q 99 native R1(config-subif)#ip address 172.17.99.1 255.255.255.0

6-7-2- Verification

Step 1: Checking the routing table on R1 R1#show ip route

Step 2: Verify Router Trunking Configuration show vlans command to Match Sample Router Trunking Configuration.

R1#show vlans

Step 3: Ping PC1 from PC2

Ping from host PC2 to host PC1. Routing between VLANs has been configured so the ping should be successful.
