Lab 11 - HDLC

3.3846153846154 1 1 1 1 1 Rating 3.38 (13 Votes)

Introduction

HDLC is a data link protocol used on synchronous serial data links. Because the standardized HDLC cannot support multiple protocols on a single link (lack of a mechanism to indicate which protocol is carried), Cisco developped a proprietary version of HDLC, called cHDLC, with a proprietary field acting as a protocol field. This field makes it possible for a single serial link to accommodate multiple network-layer protocols.

Cisco’s HDLC is a point-to-point protocol that can only be used on serial links or leased lines between two Cisco devices. PPP has to be used when communicating with non-Cisco devices. HDLC is the default encapsulation on serial links in a Cisco router. However, to change the encapsulation back to HDLC from PPP, use the following command from interface configuration mode:

Router(config-if)#encapsulation hdlc

With a back-to-back serial connection, the ISR router connected to the DCE end of the serial cable provides the clock signal for the serial link. This clock is received by the DTE device. The clock rate command in the interface configuration mode enables the router at the DCE end of the cable to provide the clock signal for the serial link. The default clock rate is 64000.

Lab 6 - Basic router setup

2.8269230769231 1 1 1 1 1 Rating 2.83 (52 Votes)

Introduction

At the first boot of a Cisco ISR router, some basic configuration has to be performed to secure adminitrative access to the router. This lab will test your ability to configure the basic security settngs of a Cisco ISR router and help you to get ready for the router configuration simulation activities in the CCENT / ICND1 certification exam (Chapter 5.0 Infrastructure Maintenance of Cisco Certified Entry Networking Technician (CCENT) exam)

Lab 4 - Port security

2.9672131147541 1 1 1 1 1 Rating 2.97 (61 Votes)

Introduction

A growing challenge for network administrators is to be able to control who is allowed - and who isn't - to access the organization's internal network. This access control is mandatory for critical infrastructure protection in your network. It is not on public parts of the network where guest users should be able to connect.

Port security is a feature implemented in Cisco Catalyst switches which helps network engineers in implementing network security on network boundaries.

In its most basic form, the Port Security feature remembers the MAC address of the device connected to the switch edge port and allows only that MAC address to be active on that port. If any other MAC address is detected on that port, port security feature shutdown the switch port.

The switch can be configured to send a SNMP trap to a network monitoring solution to alert that a port is disabled for security reasons.

Lab 3 - VLAN and VTP configuration

3.3764705882353 1 1 1 1 1 Rating 3.38 (85 Votes)

Network diagram

The aim of this lab is to test your ability to configure VLAN and VTP on a small network of 4 switches using Packet Tracer 7.2.1.

This lab will help you to prepare the VTP testlet and simlet questions of the Cisco ICND1 exam.

 

Lab instructions

1.Configure the VTP-SERVER switch as a VTP server

2.Connect to the 3 other switches and configure them as VTP clients.
All links between swiches must be configured as trunk lines.

3.Configure VTP domain name as "TESTDOMAIN" and VTP password as "cisco"

4.Configure VLAN 10 with name "STUDENTS" and VLAN 50 with name "SERVERS"

5. Check propagation on all switches of the VTP domain.

 

VLAN and VTP lab solution

1. Configure the VTP-SERVER switch as a VTP server

VTP-SERVER(config)#vtp mode server

Verify the VTP operating mode using the show vtp status command

VTP-SERVER#show vtp status
VTP Version                     : 2
Configuration Revision          : 4
Maximum VLANs supported locally : 255
Number of existing VLANs        : 7
VTP Operating Mode              : Server
VTP Domain Name                 : TESTDOMAIN
VTP Pruning Mode                : Disabled
VTP V2 Mode                     : Disabled
VTP Traps Generation            : Disabled
MD5 digest                      : 0xAE 0x4F 0x3F 0xC5 0xD3 0x41 0x9C 0x11
Configuration last modified by 192.168.1.1 at 3-1-93 00:27:41
Local updater ID is 192.168.1.1 on interface Vl1 (lowest numbered VLAN interface found)

 
2. Connect to the 3 other Catalyst switches and configure them as VTP clients.
All links between swiches must be configured as trunk lines.

VTP-CLIENT3(config)#vtp mode client

VTP-CLIENT3(config)#vtp mode client

Verify the VTP operating mode of the switch using the show vtp status command. The "VTP Operating Mode" shoud have the"Client" value. Example with VTP-CLIENT3 switch is provided below.

VTP-CLIENT3#sh vtp status
VTP Version                     : 2
Configuration Revision          : 4
Maximum VLANs supported locally : 255
Number of existing VLANs        : 7
VTP Operating Mode              : Client
VTP Domain Name                 : TESTDOMAIN
VTP Pruning Mode                : Disabled
VTP V2 Mode                     : Disabled
VTP Traps Generation            : Disabled
MD5 digest                      : 0xAE 0x4F 0x3F 0xC5 0xD3 0x41 0x9C 0x11
Configuration last modified by 192.168.1.1 at 3-1-93 00:27:41

 
Configure each link between switches as a trunk line using the switchport mode truink command

interface GigabitEthernet1/1
switchport mode trunk

interface GigabitEthernet1/2
switchport mode trunk

 

3. Configure VTP domain name as "TESTDOMAIN" and VTP password as "cisco"

On the VTP server Catalyst switch:

VTP-SERVER(config)#vtp domain TESTDOMAIN
VTP-SERVER(config)#vtp password cisco

On each VTP client switch :

VTP-CLIENT1(config)#vtp password cisco
VTP-CLIENT1(config)#vtp domain TESTDOMAIN

 
4. Configure VLAN 10 with name "STUDENTS" and VLAN 50 with name "SERVERS"

On the VTP server Catalyst 2960 switch, configure the following commands to create both "STUDENTS" and "SERVERS" vlans :

VTP-SERVER(config)#vlan 10
VTP-SERVER(config-vlan)#name STUDENTS
VTP-SERVER(config)#vlan 50
VTP-SERVER(config-vlan)#name SERVERS

 
5. Check propagation of both "STUDENTS" and "SERVERS" vlans on all Catalyst 2960 network switches of the VTP domain.

Use the show vlan brief on each switch to check propagation of the 2 VLANS.

VTP-SERVER#show vlan brief

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Fa0/1, Fa0/2, Fa0/3, Fa0/4, [...]
10   STUDENTS                         active    
50   SERVERS                          active    
1002 fddi-default                     active    
1003 token-ring-default               active    
1004 fddinet-default                  active    
1005 trnet-default                    active

Lab 2 - Switch interfaces configuration

3.3367346938776 1 1 1 1 1 Rating 3.34 (98 Votes)

Network diagram

This lab will test your ability to configure speed, duplex, and vlan settings on the network interfaces of a Catalyst 2960 switch using Cisco Packet Tracer 7.2.1.

 

Lab instructions

1. Connect to Switch0 using console interface and configure each Switch0 fastethernet switchport for operation.

Settingsto be configured on each port are :

  • Port type : access port
  • Speed : 100 Mbit/s
  • Duplex mode : Full Duplex
  • Autonegotiation disabled

 

2. PC "192.168.1.4" seems to be unable to ping other PCs in the network. Check switch configuration.
TIP : How many broadcast domains are there in this network ?

  

 

3. Choose the right cable to connect :

  • Switch0 gigabitethernet 1/1 to Switch1 gigabitethernet 1/1
  • Switch1 gigabitethernet 1/2 to Switch2 gigabitethernet 1/2

 

4. Configure those two links as trunk lines without using trunk negotiation between switches
