5) ClickAuto Discovery to initiate discovery of your devices.15. List auto-discovered devices.

a. Click the Home tab.b. Do you see your devices listed underView snapshot and Switches?

If not, troubleshoot as follows, beginning by verifying the basics:

1) Can you ping the device from Server_1 (the Windows Server 2008)?2) Are the SNMP RO and RW communities the same on the device and

on IMC?

RO = public RW = private3) Verify that you can access the devices using Telnet without a password

and that you access the privileged level. You can also review yourTelnet settings on the switch.

If the previous settings are correct, attempt to use Manual Discovery in IMC.

1) Select the Home > Function Navigation tabs, or select the Resource >Resource Management tabs.

2) Find theAdd Device option.3) Enter your devices IP address, SNMP information, and Telnet settings

to discover the device manually.

Figure 2-6: IMC > Resource > Resource Management > Add Device

Your devices might be classified as Desktop, which refers to devices withICMP enabled (they are pingable) but SNMP disabled. If your devices areclassified as Desktop, what can you do to fix this?

1) Double-check the SNMP setup on the devices and in IMC.2) Try to discover the device manually after have deleted it from the Snap-

Shot views.

16. In this step, you enable SSH on devices. Keep in mind that IMC does not createSSH public keys. On all your switches, configure the following:

a. Set the crypto public key and enable SSH if it is not enabled yet.On Cisco switches, enter:

Ci sco- A( conf i g)# cr ypt o key generate rsa usage- keys modul us1024

Ci sco- A( conf i g) # i p ssh ver si on 2


[ HP- C] publ i c- key l ocal creat e r sa

[ HP- C] ssh ser ver enabl e

On HP E-Series, a key is created by default (in the up-to-date software). If youneed to generate a key, enter this command:

HP- E(conf i g) # cr ypt o key generat e ssh rsa

HP- E( conf i g) # i p ssh

The latter command is enabled by default.

L2.1 12 Rev. 11.12

b. Attempt to establish an SSH connection from Server_1 (the Windows Server2008) using TeraTerm 4.1 or the Putty application.

17.Do not save your configuration. You will not use this configuration in later labs.However, you can save the configuration for your own records if you want. In

this case, you can either: View the running-config and copy and paste it in your own text file. Save the configuration using a different name than the one previously set

(which was interop2a).

This configuration contains the switchs basicconfiguration: name of the device, IP address in VLAN 1, default gateway, LLDPenabled, and Telnet enabled without authentication and with privileged access.

a. Verify that the interop2a config file is the startup configuration.b. If not, make it the startup configuration and reboot.On Cisco switches (both Cisco-A and Cisco-B), enter:

Ci sco- A# show boot

Ci sco- A( conf i g) # boot conf i g f l ash: i nt er op2a. cf g

4. In this step, you will create the VLANs, configure the trunk/tagged ports, andconfigure the access ports.

a. Create VLANs 11, 12, and 13 on allswitches.On Cisco switches (both Cisco-A ad Cisco-B), enter:

Ci sco- A( conf i g) # vl an 11- 13


[ HP- C] vl an 11 t o 13


HP- E( conf i g) # vl an 11

HP- E( vl an- 11) # vl an 12

HP- E( vl an- 12) # vl an 13

What are the show and display commands that list the created VLANs?

b. Configure the uplink ports (connected or not) of each switch as trunk ports.Note

We use the word trunk as used on Cisco and HP A-Series. On HP E-Seriesswitches, the term trunk refers to a link-aggregation group. All ports can acceptuntagged and tagged VLAN assignments.

On Cisco switches, configure a range of ports, P1 to P4, as trunks:

Ci sco- A( conf i g) # i nt er f ace r ange gi 1/ 0/ 1- 4

Ci sco- A( conf i g- i f - r ange) # swi t chpor t t r unk encapsul at i ondot 1q

Ci sco- A( conf i g- i f - r ange) # swi t chpor t mode t r unk

On the HP A-Series switch, configure both uplinks as trunks:

[ HP- C] i nt er f ace Gi gabi t Et her net 1/ 0/ 1

[ HP- C- Gi gabi t Et her net 1/ 0/ 1] por t l i nk- t ype t r unk

[ HP- C- Gi gabi t Et her net 1/ 0/ 1] por t t r unk per mi t vl an al l


[ HP- C- Gi gabi t Et her net 1/ 0/ 2] por t l i nk- t ype t r unk

[ HP- C- Gi gabi t Et her net 1/ 0/ 2] por t t r unk per mi t vl an al l

Note

Do not forget to permit VLANs on the trunk. On HP A-Series switches, none areenabled by default except VLAN 1.

On HP A-Series switches, you can alternatively create a manual port group andthen configure that group as a trunk:

[ HP- C] por t - group manual Upl i nks

[ HP- C- por t - gr oup- manual - Upl i nks] gr oup- member Gi 1/ 0/ 1 t oGi 1/ 0/ 2

[ HP- C- por t - gr oup- manual - Upl i nks] por t l i nk- t ype t r unk

[ HP- C- port - gr oup- manual - Upl i nks] por t t r unk per mi t vl an al l

[ HP- C] di spl ay vl an 11 t o 13

On the HP E-Series switch, you configure VLAN tagging on a port from theVLAN context:


HP- E( vl an- 11) # t agged 1- 2

HP- E( vl an- 11) # vl an 12

Configuring VLANs

Rev. 11.12 L3.1 5

HP- E( vl an- 11) # vl an 13


You can also enter this command in this way:

HP- E( conf i g) # vl an 11 t agged 1- 2

HP- E( conf i g) # vl an 12 t agged 1- 2HP- E( conf i g) # vl an 13 t agged 1- 2

NoteBy default, all E-Series switch ports are untagged in VLAN 1 by default. You canchanged the untagged membership with this command:vlan untagged .

What are the show and display commands on the different platforms thatdisplay the status of trunk ports and the VLANs that they support?

c. On HP-C and E, make sure that P3 is configured as an access port in VLAN1.

d. Make sure that Server_1 is connected on port P3 of HP-C and that PC2 isconnected on port P3 of HP-E.

e. Verify that Server_1 (10.POD.1.100) can ping PC2 (10.POD.1.101).f. On Cisco-A, HP-C, and HP-E, choose a range of three ports that are not

connected. Configure these ports as access ports in VLAN 11. (If not enoughports are available, you can choose fewer.)


Ci sco- A( conf i g) #i nt er f ace range gi gabi t 1/ 0/ 10- 12

Ci sco- A( conf i g- i f - r ange)#swi t chport mode access

Ci sco- A( conf i g- i f - r ange) #swi t chpor t access vl an 11

On HP A-Series switches, configure the ports using a manual port group. Enter:

7/30/2019 LG1_00314282

[ HP- C- por t - gr oup- manual - Edges] por t l i nk- t ype access

[ HP- C- por t - gr oup- manual - Edges] por t access vl an 11

On HP A-Series switches, you can also easily set access ports this way:

[ HP- C] vl an 11

[ HP- C- vl an11] por t Gi g 1/ 0/ 10 to Gi g 1/ 0/ 12

On HP E-Series switches, you complete the configuration in this way:


HP- E(vl an- 11) # unt agged 10- 12

Also configure P3 on the HP E-Series switch as an untagged member of VLAN11. You will connect PC2 to this port in order to test DHCP:

HP- E(conf i g)# vl an 11 unt agged 3What are the show and display commands that display the status of accessports and what VLANs theyre in with on the different platform?

g. Configure the voice ports. Select another range of three ports on HP-C andE. (If not enough ports are available, you can choose fewer.)

Configure both ports with these settings:

VLAN 11 (the data VLAN) is untagged. VLAN 12 (the voice VLAN) is tagged.

On HP A-Series switches, configure the ports using a manual port group. Enter:

[ HP- C] por t - group manual Phones

[ HP- C- por t - group- manual - Phones] group- member Gi 1/ 0/ 13 t o Gi1/ 0/ 15

[ HP- C- por t - gr oup- manual - Phones] port hybr i d pvi d vl an 11

[ HP- C- por t - gr oup- manual - Phones] UNDO por t hybr i d vl an 1

NoteOn hybrid A-Series ports (as on trunk ports), when you change the PVID (ornative VLAN), VLAN 1 remains on the ports as an untagged VLAN. For thisreason, you must remove VLAN 1 if you do not want it to remain untagged onthe port.

On HP E-Series switches, you create voice ports by giving the ports an untaggedassignment in the data VLAN and a tagged assignment in the voice VLAN.Enter:

HP- E(conf i g)# vl an 11 unt agged 13- 15


HP- E( vl an- 12) # voi ce

HP- E(vl an- 12) # t agged 13- 15

5. On Cisco-A and Cisco-B, complete these steps:a. Enable IP routing.b. Configure an IP address on interfaces VLAN 11, 12 and 13.

Use this addressing scheme: 10.POD.VLAN.X/24

POD is the number of your group, and VLAN is the VLAN ID. Replace Xdepending on the device as follows:

X=1 on Cisco-A X=2 on Cisco-B

c. Configure DHCP relay to direct DHCP requests to 10.POD.1.3.On Cisco switches, enter:

Ci sco- A( conf i g) # i p r out i ng

Ci sco- A( conf i g) # i nt er f ace vl an 11

Ci sco- A( conf i g- i f ) # i p addr ess 10. POD. 11. 1 255. 255. 255. 0

Ci sco- B( conf i g- i f ) # i p hel per - addr ess 10. POD. 1. 3

NoteIn this lab, the HP switches do not need to implement DHCP relay.

For your reference, if you did need to configure DHCP relay, you would do sowith these commands on an HP E-Series switch:

HP-E(config)# vlan x ip address 10.POD.X.5/24

HP-E(config)# vlan x ip helper 10.POD.1.3

And you would enter these commands on the HP A-Series switch:[HP-C] dhcp enable

[HP-C] dhcp relay server-group 1 ip 10.POD.1.3

[HP-C] interface vlan-interface X

[HP-C-Vlan-interfaceX] ip address 10.POD.1.3

[HP-C-Vlan-interfaceX] dhcp select relay

[HP-C-Vlan-interfaceX] dhcp relay server-select 1

6. Configure DHCP on HP-C, which will act as the DHCP server.Enable the DHCP server on VLANs 1, 11, 12, and 13. Then create pools for the

IP subnets associated with the VLANs. Use these settings for the DHCP pools: The network is 10.POD.VLAN.X/24. Exclude addresses from 10.POD.VLAN.1 to 10.POD.VLAN.101 as well as

10.POD.VLAN.254. (10.POD.VLAN.254 will be used a virtual IP in a laterlab.)

Define the default gateway to be 10.POD.VLAN.1. Set the lease time to 2 hours.

[ HP- C- pool - vl anX- pool ] net work 10. POD. X. 0 24

[ HP- C- pool - vl anX- pool ] gat eway- l i st 10. POD. X. 254[ HP- C- pool - vl an1- pool ] expi r ed day 0 hour 2

NoteIn the commands, replace POD with your POD number and X with the VLANnumber. Repeat the commands for each VLAN.

You can configure other settings, but these are not required for the lab.

[ HP- C- pool - vl anX- pool ] dns- l i st 10. POD. 1. 100

[ HP- C- pool - vl anX- pool ] domai n- name exampl e0X. hp. com

[ HP- C] dhcp server f orbi dden- i p 10. POD. X. 254

7. To verify that DHCP is working, connect PC2 to P3 HP-E. Configure PC2 toobtain its IP address using DHCP.

8. Verify that PC2 receives an IP address in the subnet for VLAN 11(10.POD.11.0/24).

9. Save the configuration of your devices for later use and define the savedconfiguration as the startup-config.

On Cisco switches:




Ci sco- A( conf i g) #boot conf i g f l ash: i nt er op- 3a. cf gCi sco- A# show boot


On HP A-Series switches:

10.The next steps are for an optional task, in which you activate GVRP on HP-C andE.

a. First enable GVRP globally on HP-C and HP-E.b. Second, enable GVRP on uplinks. You must enable GVRP on HP A-Series

ports, which must be trunk ports. On HP E-Series, GVRP is enabled on allports by default when you enable the feature globally.

On the HP A-Series switch, enter:

[ HP- C] gvrp

[ HP- C] i nt gi 1/ 0/ 1

NoteBy default, GVRP registers all VLANs on the interfaces on which it is enabled.

On HP E-Series switches, after you have enabled GVRP globally, the switch canautomatically learn VLANs on allports. Enter these commands:

HP- E( conf i g) # gvrp

10.On HP-C, enter the command to set standard MSTP port costs:[ HP- C] st p pat hcost - st andar d dot1t

Verify that the cost value has changed. The standard cost for a Gigabit portis 20000.

11.Configure uplink ports as non-edge ports. Other ports should be edge ports.On Cisco switches, you can configure all ports to be edge ports by default; ifthey receive BPDU, they transit to non-edge ports. You can also set the rolesmanually:

NoteYou must understand MSTPs IST master.

If an MST bridge is the root bridge for the CST, then it is the IST master of thatMST region. If the CST root is outside the MST region, as in this lab, in whichthe CST root is Cisco-A, one of the MST bridges at the boundary is selected asthe IST master. In this lab, the IST master for each region is the only HP switch inthat region. Other bridges on the boundary that belong to the same regioneventually block the boundary ports that lead to the root. However, this does notoccur in this lab because each HP switch communicates BPDUs through the

Cisco switch.

11.On the Cisco switches, find the following information:Which switch is root in the following VLANs:

VLAN 1? ______________________________________________________ VLAN 11? ______________________________________________________

Implement load balancing between VLANs (optional)This part of lab is optional but recommended.

In the module, you learned about how to adjust a configuration to implement loadbalancing by sending traffic over various uplinks depending on the VLAN. You will

now implement load balancing by adjusting the cost on switches ports.

22.On both Cisco switches, change the port cost of uplink P1 (the port between thetwo Cisco switches) as follows:

30000 in VLAN 1 10000 in VLANs 11-13Ci sco( conf i g) #i nt er f ace gi g 1/ 0/ 1

Ci sco( conf i g- i f ) #spanni ng- t r ee vl an 1 cost 30000

Ci sco( conf i g- i f ) #spanni ng- t r ee vl an 11- 13 cost 10000

NoteAs usual, enter the correct interface ID according to your Port Mapping table.

23.Verify that the Cisco switches are correctly blocking ports. Each switch shouldblock the port for the VLAN in which it is secondary root:

Ci sco# show spanni ng- t r ee vl an 1



Which switch blocks the ports in the following VLANs:

In VLAN 1: _______________________________________________________ In VLAN 11: ______________________________________________________ In VLAN 12: ______________________________________________________ In VLAN 13: ______________________________________________________
