Lab 8:

Spanning-Tree Protocol Root Bridges using the IOS Macro

Lab Objective:
The objective of this lab exercise is to use the macro in Cisco IOS to configure a switch to automatically adjust its Spanning Tree priority for a particular VLAN, or group of VLANs, ensuring that it is most likely elected Root Bridge.
Lab Purpose:
VLAN Root Bridge configuration is a fundamental skill. It is always recommended that the Root Bridge be manually configured to ensure that the Layer 2 network is deterministic. However, the macro available in Cisco IOS can also be used. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure a switch as a Root Bridge using the macro available in Cisco IOS.
Certification Level:
This lab is suitable for CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 10/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 15 minutes
Lab Topology:

Task 1:
In preparation for VLAN configuration, configure a hostname on Sw1 and Sw2 and configure the VLANs depicted in the topology above.
Task 2:
Configure the switches to support the VLANs listed in the topology. Configure the VLANs and check that they are visible on both switches. Configure FastEthernet0/1 on both switches as a trunk.
Task 3:
Configure switch Sw1 as Root Bridge for VLANs 2010 and 2030. Configure switch Sw2 as Root Bridge for VLANS 2020 and 2040. Configure the switches to automatically update their priorities as follows:
(a) Switch Sw1 will always be the Root Bridge for VLANs 2010 and 2030 and switch Sw2 will always be the backup root for those VLANs.
(b) Switch Sw2 will always be the Root Bridge for VLANs 2020 and 2040 and switch Sw1 will always be the backup root for those VLANs.
Task 4:
Verify your configuration with the appropriate commands.

Lab 9:

Assigning Multiple Instances to a VLAN Simultaneously


Lab Objective:
The objective of this lab exercise is to understand how to configure many interfaces that share the same common configuration at the same time without having to do them one at a time
Lab Purpose:
Configuring multiple interfaces on a switch at the same time is a fundamental skill. Some high end Cisco Catalyst switches can have in excess of 500 interfaces that may need to be configured almost identically. In such situations, configuring a single interface at a time would not be acceptable. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure multiple switch interfaces at the same time using user defined macros.
Certification Level:
This lab is suitable CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 10/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 10 minutes
Lab Topology:
You can use any standalone (single) switch to complete this lab. This lab is strictly about configuration syntax.
Task 1:
Configure a hostname of your liking on your lab switch, which should have at least 24 ports.
Task 2:
Configure VLAN 10 named SALES on the switch and VLAN 20 named TECH on the switch.
Task 3:
To simplify configuration tasks, you should create a macro called VLAN_10_Macro for configuring ports FastEthernet0/1 – FastEthernet0/12 that will be in VLAN 10 and a macro called VLAN_20_Macro for configuring ports FastEthernet0/13 – FastEthernet0/24 that will be in VLAN 20.

NOTE: Because this lab is to practice macro configuration, do NOT use the interface range command.

Task 4:
Configure interfaces FastEthernet0/1 – 12 and FastEthernet0/12 - 24 in VLAN 10 and VLAN 20, respectively, using the macro. These ports should be configured as Access ports.
Task 5:
Verify your configuration using the appropriate commands in Cisco IOS.

Lab 10:

Configuring Spanning-Tree Protocol for Access ports (Portfast)
Lab Objective:
The objective of this lab exercise is to configure Access ports to transition immediately to a Forwarding state, instead of going through the typical Spanning Tree states, i.e. Blocking, Listening, Learning, etc.
Lab Purpose:
Bypassing default Spanning-Tree port states is a fundamental skill. By default, it can take up to 60 seconds for a switch port to transition to the Forwarding state and begin forwarding frames. In most cases, this is acceptable; however, on a network with DHCP clients, for example, that need IP addressing information from a DHCP server, this duration may cause these clients to think the DHCP server is unavailable.
Certification Level:
This lab is suitable for both CCENT and CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 4/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 10 minutes
Lab Topology:
Please use the any single switch for this lab. This lab is strictly about validating command syntax.
Task 1:
Configure a hostname of your liking on your lab switch, which should have at least 12 ports.
Task 2:
Configure VLAN 10 named SALES on the switch.
Task 3:
Configure ports FastEthernet0/1 and FastEthernet0/2 using the interface range command so that Spanning-Tree protocol transitions these interfaces into a forwarding state immediately. These interfaces should also be configured as access ports in VLAN 10.
Task 4:
Verify your configuration using the appropriate commands in Cisco IOS.

Configuring switch Access port security

Configuring switch Access port security

Lab Objective:
The objective of this lab exercise is to configure basic switch security to prevent MAC address flooding on switch ports. This is accomplished by limiting the number of MAC entries that are allowed to be learned on a port. By default, there is no limit on MAC addresses that can be learned on a port.
Lab Purpose:
Port security is a fundamental skill. A Common Denial of Service technique used to cripple switched networks is MAC flooding. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure port security to mitigate MAC flooding attacks.
Certification Level:
This lab is suitable for CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 8/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 15 minutes
Lab Topology:
Please use the following topology to complete this lab exercise:





Task 1:
Configure a hostname of Sw1 on your lab switch, and the hostname R1 on the router as illustrated in the topology.


Task 2:
Create VLAN 10 on switch Sw1 and assign port FastEthernet0/2 to this VLAN as an access port.


Task 3:
Configure IP address 10.0.0.1/30 on router R1's FastEthernet0/0 interface, and IP address 10.0.0.2/30 in switch Sw2's VLAN 10 interface. Verify that R1 can ping Sw1 and vice versa.


Task 4:
Configure port security on port FastEthernet0/2 on switch Sw1 so that only 1 MAC address is allowed to be learned on that interface. In the event of port security configuration violations, where more than 1 MAC address is observed on that interface, the switch should shut the interface down. Verify your configuration with port security commands in Cisco IOS.

Lab 12:

Configuring advanced switch Access port security

Lab Objective:

The objective of this lab exercise is to ensure that learned MAC addresses on a secured port are retained in the switch NVRAM in the event of a reboot. By default, secured MAC addresses are flushed during switch reboots.


Lab Purpose:
Retaining learned secure MAC addresses is an advanced skill. When a Cisco Catalyst switch configured with port security reboots, learned secure MAC address entries are flushed and have to be re-learned when the switch comes back up. As a Cisco engineer, understanding advanced features will give you the edge over fellow CCNAs.


Certification Level:
This lab is suitable for CCNA certification exam preparation


Lab Difficulty:
This lab has a difficulty rating of 10/10


Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 15 minutes

Task 1:
Configure a hostname of Sw1 on your lab switch, and the hostname R1 on the router as illustrated in the topology.


Task 2:
Create VLAN 10 on switch Sw1 and assign port FastEthernet0/2 to this VLAN as an access port.


Task 3:
Configure IP address 172.16.0.1/27 on router R1's FastEthernet0/0 interface, and IP address 172.16.0.2/27 in switch Sw2's VLAN 10 interface. Verify that R1 can ping Sw1, and vice versa.


Task 4:
Configure port security on port FastEthernet0/2 on switch Sw1 so that any MAC addresses learned on that interface are written to the switch NVRAM. The NVRAM is the startup-configuration. Verify your configuration with port security commands in Cisco IOS.
