Hands on Lab Objectives

During this activity you will learn how to:

install the HP Network Simulator on a Windows workstation

create and manage network simulation projects using the graphical user interface (GUI)

define simulated devices and links

configure basic network features on Comware devices

Introduction

HP IRF (Intelligent Resilient Framework) IRF is a virtualization technology that combines multiple physical devices (stackable and modular) into a single logical device. More about IRF at http://h17007.www1.hp.com/docs/reports/irf.pdf During this activity two groups of two learners each will create a distributed simulated network composed of four switches and two routers as shown in Figure 1.

Step 1: Install the simulator

Verify that Oracle VM VirtualBox is installed. Look for the following icon:

On the desktop locate and run the file: HNS_7.1.50-Setup and follow the installation instructions accepting all the default parameters

If the installation is successful you will find the following icon on your desktop:

Configure the IP Address of the PCs physical and VirtualBox NICs

Table 1: IP Addresses PC A

Step 2: Create the simulation

Note

As the simulation spans two PCs, the same project must be created on both PCs including the definition of all devices and links

From the desktop:

o Click on the HP Network Simulator icon to open the GUI.

o Identify all the icons on the GUI

Figure 3: HP Network Simulator GUI

You will use this tool to create the devices and links shown in Figure 4.

Figure 4: Devices, interfaces and links for group N

On the desktop locate and open the file: HP Network Simulator HOL - Gr n - PCx - Simulator Script

Create the project by copying the contents of this file to the GUI. You can copy and paste the whole text or enter each line manually

Figure 5: Creating the network simulation project

Save the project

Analyze the commands you have copied and notice the following:

o Device models:

SIM1100: router with 3 GbE ports (2-4) and 4 Serial ports (5-8) and 1 Ethernet Management port (1)

SIM2100: stackable switch with 7 GbE ports (2-7) and 1 Ethernet Management port (1)

Table 2: Port types and numbering

1 2 3 4 5 6 7 8

SIM1100 M-Ethernet 1/0/1 Gig 0/0/2-4 Gig 0/0/5-8

SIM2100 M-Ethernet 1/0/1 Gig 1/0/2-8

o memory size: this device parameter allocates the memory necessary for the Telnet server

o host-ip: this device parameter allows devices on different PCs to communicate

o Links: Compare the link commands with the links in Figure 4

o host: this link parameter creates the connection used by the Telnet client on the PC server on the device to communicate. It must be the name of the actual VirtualBox network interface as found in the vboxnet0 Properties

Step 3: Launch the simulation

On the GUI, launch the project by clicking on the Run icon

The VirtualBox Manager will open and the virtual machines of each device will be located under the hol_discover group

Figure 8: Oracle VM VirtualBox Manager

Note

Before continuing, ensure that the group members on the other PC have reached this same point.

Start the VMs of the devices on your PC

o On PC A: start device11, device12 and device13

o On PC B: start device21, device22 and device23

Watch the console window of each device and wait for the Started automatic configuration message

Click to break the retry cycle, then press

To leave the VM window, press the right Ctrl key to release the cursor.

IMPORTANT When using the console of a VM the mouse and the keyboard are captured by VirtualBox. To release them press the right-control key.

Step 4: Configure IRF

IRF will allow your switches to behave as a single switching and routing entity. To configure IRF take the following steps 1. Change the device number of the second switch from 1 to 2 2. Configure the IRF-port on each switch 3. Reboot the first switch (it will become the IRF master device) 4. Reboot the second switch (it will become an IRF standby device) 5. Verify the IRF configuration and topology

Figure 9: IRF Configuration

On the second switch (Device13 on PC A, and Device 23 on PC B) enter the following commands:

system-view irf member 1 renumber 2 quit

Save the configuration

save

Reboot the device

reboot

On the first switch (Device12 on PC A, and Device 22 on PC B) create the IRF-port 1/1. Enter the following commands:

system-view irf-port 1/1 port group int gig 1/0/2 quit int gig 1/0/2 undo shutdown quit

o Save the configuration

On the second switch (Device13 on PC A, and Device 23 on PC B) create the IRF-port 2/2. Enter the following commands (notice that the device number has changed from 1 to 2 and the port numbering has changed from 1/0/n to 2/0/n):

system-view irf-port 2/2 port group int gig 2/0/2 quit int gig 2/0/2 undo shutdown quit


save

10

Reboot the first switch (Device 12, 22) and after 15-20 seconds, reboot the second switch (Device 13, 23)

reboot

When both devices have completed the reboot, on the first enter:

display irf display irf configuration display irf topology

Figure 10: Logical topology after IRF configuration

Note

Once the IRF-stack is established, both switches behave as one and can be managed from the console of the IRF Master.

Step 5: Configure the parameters for Telnet management

On the router and the IRF-stack, take the following steps to make Telnet available

o Configure the Telnet interface and enable the Telnet server

system-view user-interface vty 0 63 authentication-mode none user-role network-admin quit telnet server enable

o Configure the IP address of the Ethernet management interface.

Note

Use the IP addresses shown in Table 3, replacing N with your group number.

Table 3: Management IP addresses

PC A PC B

Router 10.N.0.211/24 10.N.0.221/24

IRF-stack 10.N.0.212/24 10.N.0.222/24

interface m-ethernet 1/0/1 ip address 10.N.0.2xx 24 quit quit


save

Note

The rest of the configuration can be entered using a Telnet client utility: PUTTY. The advantage of using this tool is that it allows

to cut and paste commands to and from the CLI.

o Copy the router section from the file and paste it on the Telnet client


Configure the IRF-stack

o Open a second PUTTY session and connect to the Router

o Copy the switch section from the file and paste it on the CLI


Sign up for updates

Step 7: Verify the configuration

Note

Before continuing, ensure that the group members on the other PC have reached this same point. Perform the following steps

in synchronization with the other group members and compare results.

Verify that the all the interfaces are up.

display interface brief

Verify that all the routes have been established

display ip routing-table

Verify IP connectivity. From the console of the IRF-stack ping the loopback address of the IRF-stack on the other PC

ping 10.N.254.x

If ping fails, troubleshoot. Call the facilitator for help if needed

Step 8: Shut down the devices, close and delete the project

Make sure that the other members of your group have finished testing the network

Close the Telnet windows

Close the VirtualBox VMs

Close the VirtualBox Manager

From the HP Network Simulator GUI delete the project by clicking on the remove icon

Close the GUI
