!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!
Objective:
Set up a VTP domain, create and maintain VLANs, and use Inter-Switch Link
(ISL) and 802.1Q trunking on Cisco Catalyst 2960 and 3560 series Ethernet
switches using command-line interface (CLI) mode.
Scenario:
Prepare a Catalyst 2960 or 3560 switch to be used in a lab.
Basic Configuration:
DLS1 & DLS2:
enable
configure terminal
!
no ip domain lookup
!
vtp mode transparent
!
line console 0
logging synchronous
exec-timeout 0 0
!
interface range FastEthernet 0/1 -24
shutdown
exit
!
interface range gigabitEthernet 0/1 - 2
shutdown
exit
!
hostname DSL(1,2)
ALS1 & ALS2:
enable
configure terminal
!
no ip domain lookup
!
vtp mode transparent
!
line console 0
logging synchronous
exec-timeout 0 0
!
interface range FastEthernet 0/1 -24
shutdown
exit
!
interface range gigabitEthernet 0/1 - 2
shutdown
exit
!
no ip routing
!
hostname ASL(1,2)
Step 1
Start by deleting the vlan.dat file, erasing the startup config, and reloading all your switches.
All Switch:
Clearing all Switches
Step 2
By default, VLAN 1 is used as the management VLAN.
DLS1:
DSL1(config)#interface vlan 1
DSL1(config-if)#ip address 10.1.1.101 255.255.255.0
DSL1(config-if)#no shutdown
DLS2:
DSL2(config)#interface vlan 1
DSL2(config-if)#ip address 10.1.1.102 255.255.255.0
DSL2(config-if)#no shutdown
ALS1:
ASL1(config)#interface vlan 1
ASL1(config-if)#ip address 10.1.1.103 255.255.255.0
ASL1(config-if)#no shutdown
ALS2:
ASL2(config)#interface vlan 1
ASL2(config-if)#ip address 10.1.1.104 255.255.255.0
ASL2(config-if)#no shutdown
Step 3
Use the show vlan command from privileged mode on any switch.
All Switch:
All Switch#show vlan
DSL1#show vlan

Step 4
A switch can be in only one VTP domain with the same VTP domain name.
All Switch:
All Switch#show vtp status
DSL1#show vtp status
VTP Version : running VTP1 (VTP2 capable)
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 5
VTP Operating Mode : Transparent
VTP Domain Name :
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x57 0xCD 0x40 0x65 0x63 0x59 0x47 0xBD
Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00
DSL1#
Step 5
Set up the switches so that the DL switches are in VTP server mode, and the AL
switches are in VTP client mode.
DSL1(config)#vtp mode server
DSL2(config)#vtp mode server
ASL1(config)#vtp mode client
ASL2(config)#vtp mode client
Change the VTP domain name on DLS1 to SWLAB using the vtp domain command.
DSL1(config)#vtp domain SWLAB
All Switch:
All Switch#show vtp status
ASL1#show vtp status
VTP Version : running VTP1 (VTP2 capable)
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 5
VTP Operating Mode : Client
VTP Domain Name :
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x57 0xCD 0x40 0x65 0x63 0x59 0x47 0xBD
Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00
ASL1#
Step 6
The "show interfaces fastEthernet 0/1 switchport" command lists the configured
mode of each port in detail.
DSL1#show interfaces fastEthernet 0/1 switchport
Name: Fa0/1
Switchport: Enabled
Administrative Mode: dynamic desirable
Operational Mode: down
Administrative Trunking Encapsulation: negotiate
Negotiation of Trunking: On
Access Mode VLAN: 1 (default)
Trunking Native Mode VLAN: 1 (default)
Administrative Native VLAN tagging: enabled
Voice VLAN: none
Administrative private-vlan host-association: none
Administrative private-vlan mapping: none
Administrative private-vlan trunk native VLAN: none
Administrative private-vlan trunk Native VLAN tagging: enabled
Administrative private-vlan trunk encapsulation: dot1q
Administrative private-vlan trunk normal VLANs: none
Administrative private-vlan trunk associations: none
Administrative private-vlan trunk mappings: none
Operational private-vlan: none
Trunking VLANs Enabled: ALL
Pruning VLANs Enabled: 2-1001
Capture Mode Disabled
Capture VLANs Allowed: ALL
Protected: false
Unknown unicast blocked: disabled
Unknown multicast blocked: disabled
Appliance trust: none
DSL1#
Use the "interface range" command to configure all trunk ports at once for trunking.
DLS1:
DSL1(config)#interface range fastEthernet 0/7 - 10
DSL1(config-if-range)#switchport trunk encapsulation dot1q
DSL1(config-if-range)#switchport mode trunk
DSL1(config-if-range)#no shutdown
DSL1(config-if-range)#interface range fastEthernet 0/11 - 12
DSL1(config-if-range)#switchport trunk encapsulation isl
DSL1(config-if-range)#switchport mode trunk
DSL1(config-if-range)#no shutdown
DSL2:
DSL2(config)#interface range fastEthernet 0/7 - 10
DSL2(config-if-range)#switchport trunk encapsulation dot1q
DSL2(config-if-range)#switchport mode trunk
DSL1(config-if-range)#no shutdown
DSL2(config-if-range)#interface range fastEthernet 0/11 - 12
DSL2(config-if-range)#switchport trunk encapsulation isl
DSL2(config-if-range)#switchport mode trunk
DSL1(config-if-range)#no shutdown
ALS1:
ASL1(config)#interface range fastEthernet 0/7 - 12
ASL1(config-if-range)#switchport trunk encapsulation dot1q
ASL1(config-if-range)#switchport mode trunk
ASL1(config-if-range)#no shutdown
ALS2:
ASL2(config)#interface range fastEthernet 0/7 - 12
ASL2(config-if-range)#switchport trunk encapsulation dot1q
ASL2(config-if-range)#switchport mode trunk
ASL2(config-if-range)#no shutdown
ASL2(config-if-range)#
Step 7
Verify the trunking configuration of each switch using the following commands.
All Switch:
DSL1#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Fa0/7 on 802.1q trunking 1
Fa0/8 on 802.1q trunking 1
Fa0/9 on 802.1q trunking 1
Fa0/10 on 802.1q trunking 1
Fa0/11 on isl trunking 1
Fa0/12 on isl trunking 1
Port Vlans allowed on trunk
Fa0/7 1-4094
Fa0/8 1-4094
Fa0/9 1-4094
Fa0/10 1-4094
Fa0/11 1-4094
Fa0/12 1-4094
Port Vlans allowed and active in management domain
Fa0/7 1
Fa0/8 1
Fa0/9 1
Fa0/10 1
Fa0/11 1
Port Vlans allowed and active in management domain
Fa0/12 1
Port Vlans in spanning tree forwarding state and not pruned
Fa0/7 1
Fa0/8 1
Fa0/9 1
Fa0/10 1
Fa0/11 1
Fa0/12 1
DSL1#
DSL1(config)#vlan 100
DSL1(config-vlan)#exit
DSL1(config)#vlan 110
DSL1(config-vlan)#exit
DSL1(config)#vlan 120
DSL1(config-vlan)#exit
DSL1(config)#
Step 8
The Fast Ethernet ports connected to the hosts on the network can be set up as
static access because they are not to be used as trunk ports.
DSL1(config)#interface fastEthernet 0/6
DSL1(config-if)#switchport mode access
DSL1(config-if)#switchport access vlan 100
DSL2(config)#interface fastEthernet 0/6
DSL2(config-if)#switchport mode access
DSL2(config-if)#switchport access vlan 110
DSL2(config-if)#no shutdown
ASL1(config)#interface fastEthernet 0/6
ASL1(config-if)#switchport mode access
ASL1(config-if)#switchport access vlan 120
ASL2(config)#interface fastEthernet 0/6
ASL2(config-if)#switchport mode access
ASL2(config-if)#switchport access vlan 120
All Switch:
All Switch#show vlan
Step 9
Naming VLANs can help network administrators identify the functionality of those VLANs.
DLS1:
SL1(config)#vlan 100
DSL1(config-vlan)#name Server-Farm-1
DSL1(config-vlan)#vlan 110
DSL1(config-vlan)#name Server-Farm-2
DSL1(config-vlan)#vlan 120
DSL1(config-vlan)#name Net-Eng
All Switch:
All Switch#show vlan
