Lab 2.1.1a Basic Setup for the CME Router with Switch Module

Objectives

• Configure a Cisco router in preparation for CallManager Express (CME)

• Configure a switch in preparation for CME

Equipment Requirements

• Cisco CallManager Express (CME) capable router with switch module

• Workstation with an Ethernet 10/100 NIC installed

• Two Cisco IP phones

In this lab, the ACME.com Company has decided to deploy CallManager Express in the enterprise. First, the router portion (including the switch module) of CallManager Express must be configured. The routers and switch module should be configured using the information found in IP Telephony Table 1.

Step 1 Assign a Pod Number

a. Ask the instructor to assign a pod number to the lab group.

What pod number was the group assigned? ____________________

Step 2 Erasing Configuration and VLANs from the Router

a. The router with a four port switch module stores VLAN information in Flash memory. To ensure

the router does not have a previous configuration, connect a console cable to the router and

power on the router.

b. Erase the switch VLAN database and startup-configuration file by using the delete

flash:vlan.dat, erase startup-config, and reload commands.

Router# delete flash:vlan.dat Router# erase startup-config Router# reload

Step 3 Basic CME Router Configuration

a. On the router, enter privilege mode and then configuration mode.

b. Change the hostname of the router. Use the command hostname CMERouterX, where X is the

pod number assigned to the group. Throughout the rest of the lab, use IP Telephony Table 1 parameters based on the pod number assigned.

Router(config)# hostname CMERouterX

c. Set the enable secret password to cisco. (Do not deviate from this password.) d. Use the command no ip domain-lookup to disable name resolution since there is no DNS

server in the classroom lab.

CMERouterX(config)# no ip domain-lookup

e. Note that router commands are IOS and model specific. Examples given in this lab are the most

common configurations seen. However, the command may vary slightly. For example, on a 1760 router the VTY lines are 0 through 15 instead of 0 through 4. Configure all the router VTY lines with parameters similar to the following:

CMERouterX(config)# line vty 0 4 CMERouterX(config-line)# password cisco CMERouterX(config-line)# login CMERouterX(config-line)# logging synchronous

f. Configure the console port parameters.

CMERouterX(config)# line console 0 CMERouterX(config-line)# password cisco CMERouterX(config-line)# login CMERouterX(config-line)# logging synchronous

g. Create two VLANs—one for the voice VLAN and one for the data VLAN. VLAN 1, the

management VLAN, is already created. Note that the X shown in the command is the pod

number.

CMERouterX# vlan database CMERouterX(vlan)# vlan X0 name Data state active CMERouterX(vlan)# vlan X5 name Voice state active

h. Go into the configuration mode for the management VLAN by entering global configuration mode

and typing the command interface vlan 1. The management VLAN is the VLAN used to

remotely manage network devices such as routers and switches.

CMERouterX(config)# interface vlan 1

i. Configure the management VLAN interface with an IP address appropriate for the management

VLAN. From the interface configuration mode, enter the IP address for the management VLAN

based on the information found in IP Telephony Table 1. Use the command ip address 10.X.0.1

255.255.255.0 command (where X is the pod number).

CMERouterX(config-if)# ip address 10.X.0.1 255.255.255.0

j. Go into the configuration mode for the data VLAN by entering global configuration mode and

entering the command interface vlan X0 (where X is the pod number). For example, if the group was assigned to Pod 1, the command would be as follows: interface vlan 10

CMERouterX(config)# interface vlan X0

k. Configure the data VLAN interface with an appropriate IP address. From the interface

configuration mode, enter the IP address for the data VLAN based on the information found in IP

Telephony Table 1. Use the command ip address 10.X0.0.1 255.255.255.0 command (where X

is the pod number).

CMERouterX(config-if)# ip address 10.X0.0.1 255.255.255.0

m. If a host was configured on the same data VLAN, what would be the host default gateway IP

address? ________________________________________________________________

n. Go into the configuration mode for the voice VLAN by entering the global configuration mode

and entering the command interface vlan X5 (where X is the pod number).

CMERouterX(config)# interface vlan X5

o. Configure the voice VLAN with the appropriate IP address. Enter the IP address for the voice

VLAN based on the information found in IP Telephony Table 1. Use the ip address 10.X5.0.1

255.255.255.0 command (where X is the pod number).

CMERouterX(config-if)# ip address 10.X5.0.1 255.255.255.0

p. Bring EACH of the created VLAN interfaces to a useable condition.

CMERouterX(config)# interface vlan x CMERouterX(config-if)# no shutdown

q. Configure the EIGRP routing protocol by using the router eigrp 100 command to start an

EIGRP process with an autonomous system number of 100. Then enter the command

10.0.0.0, which enables and advertises EIGRP updates on all 10.0.0.0-configured interfaces.

network

CMERouterX(config)# router eigrp 100 CMERouterX

(config-router)# network 10.0.0.0

Step 4 Configure the Router Switch Ports

a. Verify the slot into which the router switch four port module inserts by (1) viewing the router and

(2) using the show diag command. Look for the words 4 Port FE Switch.

CMERouterX# show diag

b. Based on the previous step, into what slot does the switch module insert? _________________ c. Use the show ip interface brief command to verify the slot and the format used for the

interface. For example in a 2811 ISR, the four ports list as FastEthernet 0/0/0, 0/0/1, 0/0/2, and 0/0/3.

d. Write the format in which the four ports list. _________________________________________

e. Ports 0 and 1 of the switch module will be used to connect the IP phones. These ports must be

configured as trunk modes, must have the trunking protocol configured, must identify the native VLAN, and must identify the voice VLAN.

Note that the slot/port-adapter/port parameter that is typed depends on the router slot into which

the four port module inserts.

The native keyword defines this VLAN as the one that is not tagged with VLAN information when a frame (from VLAN X0) crosses the trunk between the IP phone and the switch. This

allows the PC that connects to the IP phone to be on a different subnet than the IP phone and still receive an IP address from a DHCP server. If a warning message appears, ignore it. If this command does not work, the proper router is not being used.

IMPORTANT: Note that the following commands must be done on both port 0 and port 1. An alternative to the interface fastethernet command is interface range fastethernet slot/port- adapter/port command.

CMERouterX(config)# interface fastethernet slot/port-adapter/port CMERouterX(config-if)# switchport trunk encapsulation dot1q CMERouterX(config-if)# switchport trunk native vlan X0 (where X is the pod number) CMERouterX(config-if)# switchport mode trunk CMERouterX(config-if)# switchport voice vlan X5 (where X is the pod number) CMERouterX(config-if)# no shutdown

f. What is the purpose of the dot1q parameter used in the previous step? ___________________

____________________________________________________________________________

Step 5 Verify VLAN Configuration

a. From privileged mode on the router, issue the show ip interface brief command and verify that

VLAN1, X0, and X5 (where X is the pod number) have IP addresses and that their status is up and up.

CMERouterX# show ip interface brief

b. Are all three VLAN interfaces up and up and have the proper IP address? If not, troubleshoot as

necessary. __________

If the interfaces are not there, do not have an IP address or the correct IP address, or if their status is not up and up, do not proceed until appropriate troubleshooting has been performed.

c. From privileged mode verify the port is properly configured as a trunk port by using the show

interfaces slot/port-adapter/port switchport command (where interface-id is the switch port

used to connect to the router).

CMERouterX# show interfaces fastethernet slot/port-adapter/port

switchport

d. What is the status of the switch port (shown as switchport in the command output)?

_____________________________________________________________________________

e. What is the status of the Administrative Mode? _____________________________________

f. What is the status of the Operational Mode? _________________________________________

g. What is the Operational Trunking Encapsulation that has been configured? _________________

h. What VLANs are trunked by default? _______________________________________________

i. The show interfaces trunk command can be used to verify trunk operations.

CMERouterX# show interfaces trunk

j. Based on the command output, what port(s) have trunking enabled?

_________________________________________________________________

k. Based on the command output, what VLAN is the native VLAN? (Note: The native VLAN is the

VLAN that does not tag a frame from this VLAN as it traverses the trunk with VLAN information. It is also the VLAN that continues to cross the link between the router and the switch if the trunk ever fails for any reason.) _________________________________________

l. Based on the command output, what VLANs are allowed on the trunk? ____________________

m. Based on the command output, what VLANs are participating in spanning tree and are in the

forwarding state? ______________________________

n. Connect a Cisco IP phone using a straight-through cable to the switch port 0. The port on the

bottom of the IP phone is labeled 10/100. Note that the IP phone will not work until CallManager Express has been configured.

o. Using a second straight-through cable, connect the second phone to switch port 1 on the router.

Step 6 Save the Router Configuration

a. Save the router configuration by typing the following command:

CMERouterX# copy running-config startup-config

Note: Save the router configuration to a text file as well. These configurations will be required in

future labs.

Answers to 2.1.1a lab

Lab 2.1.1b Basic Setup for the CME Router and Switch

Objectives

• Configure a Cisco router in preparation for CallManager Express (CME)

• Identify the DHCP configuration commands

• Configure a switch in preparation for CME

Equipment Requirements

• Cisco CallManager Express (CME) capable router

• Inline Power capable switch or non-inline power switch with power injectors

• Workstation with an Ethernet 10/100 NIC installed

In this lab, the ACME.com Company has decided to deploy CallManager Express in the enterprise. First, the router portion of CallManager Express must be configured. The routers and switches should be configured using the information found in IP Telephony Table 1.

Step 1 Assign a Pod Number

a. Ask the instructor to assign a pod number to the lab group.

What pod number was the group assigned? ____________________

Step 2 Basic CME Router Configuration

a. Connect to the console port of a Cisco CallManager Express router and power it on. If the router

has a configuration already on it, erase the router and reload it.

b. Enter privilege mode, and then configuration mode.

c. Change the hostname of the router. Use the command hostname CMERouterX, where X is the

pod number assigned to the group. Throughout the rest of the lab, use IP Telephony Table 1 parameters based on the pod number assigned.

Router(config)# hostname CMERouterX

d. Set the enable secret password to cisco. (Do not deviate from this password.) e. Use the command no ip domain-lookup to disable name resolution since there is no DNS

server in the classroom lab.

CMERouterX(config)# no ip domain-lookup

f. Note that router commands are IOS and model specific. Examples given in this lab are the most

common configurations seen. However, the command man vary slightly. For example, on a 1760 router the VTY lines are 0 through 15 instead of 0 through 4. Configure all the router VTY lines with parameters similar to the following:

CMERouterX(config)# line vty 0 4 CMERouterX(config-line)# password cisco CMERouterX(config-line)# login CMERouterX(config-line)# logging synchronous

g. Configure the console port parameters.

CMERouterX(config)# line console 0 CMERouterX(config-line)# password cisco CMERouterX(config-line)# login CMERouterX(config-line)# logging synchronous

h. Create a subinterface for the management VLAN by entering global configuration mode, and

typing the command interface fastethernet 0/0.1. The management VLAN is the VLAN used to

remotely manage network devices such as routers and switches.

Note: Depending on the model and physical configuration of the router, the interface could be a

FastEthernet port or a Gigabit Ethernet port. Also, the router may have a different physical interface number (i.e., FastEthernet 0 or GigabitEthernet 2/0). If unsure about which interface is

installed, verify the name of the Ethernet ports on the router by using the show running-config or show ip interface brief command.

CMERouterX(config)# interface fastethernet 0/0.1

What types of Ethernet interface(s) are on the router? ______________________________

i. Configure the subinterface for trunking by entering the command encapsulation dot1q 1. The 1

is the management VLAN number. The command instructs the router to use this subinterface for VLAN 1. If a warning message appears, ignore it. If this command does not work, the proper router is not being used.

CMERouterX(config-subif)# encapsulation dot1q 1

j. Configure the management VLAN subinterface with an IP address appropriate for the

management VLAN. From the subinterface configuration mode, enter the IP address for the management VLAN based on the information found in IP Telephony Table 1. Use the command

ip address 10.X.0.1 255.255.255.0 command (where X is the pod number).

CMERouterX(config-subif)# ip address 10.X.0.1 255.255.255.0

If a switch was configured with an IP address on the same management VLAN, what would be the default gateway IP address configured on the switch? ________________________

k. Create a subinterface for the data VLAN by entering the global configuration mode and entering

the command interface fastethernet 0/0.X0 (where X is the pod number). For example, if the group was assigned to Pod 1, the command would be as follows: interface fastethernet 0/0.10

CMERouterX(config)# interface fastethernet 0/0.X0

l. Configure the subinterface for trunking by entering the command encapsulation dot1q X0

(where X is the pod number) native. The native keyword defines this VLAN as the one that is not tagged with VLAN information when a frame (from VLAN X0) crosses the trunk between the

router and the switch. This allows the PC that connects to the IP phone to be on a different subnet than the IP phone and still receive an IP address from a DHCP server. If a warning message appears, ignore it. If this command does not work, the proper router is not being used.

CMERouterX(config-subif)# encapsulation dot1q X0 native

What is the purpose of the dot1q portion of the command?

___________________________________________________________________

m. Configure the data VLAN subinterface with an IP address appropriate for the data VLAN. From

the subinterface configuration mode, enter the IP address for the data VLAN based on the

information found in IP Telephony Table 1. Use the command ip address 10.X0.0.1

255.255.255.0 command (where X is the pod number). CMERouterX(config-subif)# ip address 10.X0.0.1 255.255.255.0

If a host was configured on the same data VLAN, what would be the host default gateway IP address? ________________________________________________________________

n. Create a subinterface for the voice VLAN by entering the global configuration mode, and

entering the command interface fastethernet 0/0.X5 (where X is the pod number).

CMERouterX(config-subif)# interface fastethernet 0/0.X5

o. Configure the subinterface for trunking by entering the command encapsulation dot1q X5

(where X is the pod number).

CMERouterX(config-subif)# encapsulation dot1q X5

p. Configure the voice VLAN subinterface with an IP address appropriate for the voice VLAN. Enter

the IP address for the voice VLAN based on the information found in IP Telephony Table 1. Use

the ip address 10.X5.0.1 255.255.255.0 command (where X is the pod number).

CMERouterX(config-subif)# ip address 10.X5.0.1 255.255.255.0

q. Bring the Ethernet interface to a useable condition.

CMERouterX(config)# interface fastethernet 0/0 CMERouterX(config-if)# no shutdown

r. Configure the EIGRP routing protocol by using the router eigrp 100 command to start an

EIGRP process with an autonomous system number of 100. Then enter the command network

10.0.0.0, which enables and advertises EIGRP updates on all 10.0.0.0-configured interfaces.

CMERouterX(config)# router eigrp 100 CMERouterX

s. Connect a straight-through cable between the Ethernet port on the router and port 1 on the

switch.

t. Verify connectivity by viewing the interfaces on the router.

CMERouterX# show ip interface brief

u. Is the Ethernet interface in a functional state?_______

If not, troubleshoot and resolve the problem. Do not proceed until the interface is up and up.

What is the status of the Status and Protocol states for the main Ethernet interface (not the subinterfaces)? ____________________________________________________________

v. Save the router configuration.

(config-router)# network 10.0.0.0

Step 3 Erasing the CME Switch

Note: The configuration output used in the lab is produced from a 2950 switch. Any other switch or

IOS may produce different output. The following steps are to be executed on each model of switch unless specifically instructed otherwise.

a. Connect a console cable to the switch and power on the switch. b. Erase the switch VLAN database and startup-configuration file by using the delete

flash:vlan.dat, erase startup-config, and reload commands.

Switch# delete flash:vlan.dat Delete filename [vlan.dat]? [Enter] Delete flash:vlan.dat? [confirm] [Enter] Switch# erase startup-config Switch(config)# reload

Step 4 Examine the current switch configuration

a. Examine the running configuration file:

Switch# show running-config

b. How many Ethernet or Fast Ethernet interfaces does the switch have? _____________

c. What is the range of values shown for the VTY lines? _________________________

d. Examine the current contents of NVRAM as follows:

Switch# show startup-config %% Non-volatile configuration memory is not present

Note that on some switches, the message does not appear.

e. If the switch gave the error message response, why does it appear?

_____________________________________________________________________________

Step 5 Assign a name to the switch

a. Enter privilege mode and then configuration mode. Use the hostname CMESwitchX command

(where X is the pod number) to name the switch. Throughout the rest of the lab, use IP

Telephony Table 1 parameters based on the pod number assigned.

Switch# configure terminal Switch(config)# hostname CMESwitchX

Step 6 Examine the current running configuration

a. From privileged mode, exam the current configuration that follows to verify that there is no

configuration except for the hostname:

CMESwitchX# show running-config

b. Are there any passwords set on the console or VTY lines? ______________________________ c. What does the configuration show as the hostname of this switch? _______________________

Step 7 Set access passwords

Enter line configuration mode for the console port. Set the password on the console port to cisco. Configure the VTY lines with the password of cisco.

CMESwitchX# configure terminal CMESwitchX(config)# line console 0 CMESwitchX(config-line)# password cisco CMESwitchX(config-line)# login CMESwitchX(config-line)# line vty 0 15 CMESwitchX(config-line)# password cisco CMESwitchX(config-line)# login

Step 8 Set the command mode password

a. Set the enable secret password to cisco.

CMESwitchX(config)# enable secret cisco

b. Which password takes precedence, the enable password or enable secret password?

_____________________________________________________________________________

Step 9 Configure Layer 3 access to the switch

a. Set the IP address of the switch to 10.X.0.4/24 (where X is the pod number). Note: This is done

on the internal virtual interface VLAN 1.

CMESwitchX(config)# interface vlan 1 CMESwitchX(config-if)# ip address 10.X.0.4 255.255.255.0 CMESwitchX(config-if)# description Management VLAN

b. What is the purpose of the management VLAN? _____________________________

_____________________________________________________________________________

c. Set the default gateway for the switch to 10.X.0.1 (where X is the pod number).

CMESwitchX(config)# ip default-gateway 10.X.0.1

d. What is the purpose of putting a default gateway on a switch? (Be specific.)

__________________________________________________________________

Step 10 Verify and activate the management VLANs settings

a. Verify the interface settings on VLAN 1 as follows:

CMESwitchX# show interfaces vlan 1

b. What is the bandwidth on this interface? ____________________________________________

c. What are the VLAN states: VLAN1 is ___________________________________________, line

protocol is _________________________.

d. What is the queuing strategy being used? ___________________________________________

e. Enable the virtual interface using the no shutdown command.

CMESwitchX(config)# interface vlan 1 CMESwitchX(config-if)# no shutdown

Step 11 Save the configuration

a. The basic configuration of the switch has just been completed. Backup the running configuration

file to NVRAM.

Note: This will ensure that the changes made will not be lost if the system is rebooted or

loses power.

CMESwitchX# copy running-config startup-config

Step 12 Configure the switch port as a trunk port

a. From global configuration mode, access switch interface port 1 that connects to the router.

CMESwitchX(config)# interface fastethernet 0/1

b. From interface configuration mode, set the switch to use the IEEE 802.1Q trunking protocol.

Note: If this command does not work on the switch, the switch only supports the 802.1Q trunking

protocol and does not have to be programmed with this command. The next step may have to be completed before this step if an older switch is being used.

CMESwitchX(config-if)# switchport trunk encapsulation dot1q

c. From interface configuration mode, set the switch to trunking mode.

CMESwitchX(config-if)# switchport mode trunk

d. The native VLAN is the one VLAN that does not have the VLAN information tagged onto the

frame as it travels across the trunk. From interface configuration mode, specify which VLAN is

the native VLAN (where X is the pod number).

CMESwitchX(config-if)# switchport trunk native vlan X0

e. Besides trunking, what are the other modes for which a switch port can be configured?

_____________________________________________________________________________

f. From enable mode verify the port is properly configured as a trunk port by using the show

interface interface-id switchport command (where interface-id is the switch port used to connect to the router).

CMESwitchX# show interfaces fastethernet 0/1 switchport

g. What is the status of the switch port (shown as switchport in the command output)?

_____________________________________________________________________________

h. What is the status of the Administrative Mode? _____________________________________

i. What is the status of the Operational Mode? _________________________________________

j. What is the Operational Trunking Encapsulation that has been configured? _________________

k. What VLANs are trunked by default? _______________________________________________

l. Some switches have another command that can be used to verify trunking operations—show

interfaces trunk.

CMESwitchX# show interfaces trunk

m. If the show interfaces trunk command is available, what port(s) have trunking enabled?

_________________________________________________________________

n. If the show interfaces trunk command is available, what VLAN is the native VLAN? (Note: The

native VLAN is the VLAN that does not tag a frame from this VLAN as it traverses the trunk with VLAN information. It is also the VLAN that continues to cross the link between the router and the switch if the trunk ever fails for any reason.) _________________________________________

o. If the show interfaces trunk command is available, what VLANs are allowed on the trunk based

on the output from this command? _____________________________

p. If the show interfaces trunk command is available, what VLANs are participating in spanning

tree and are in the forwarding state? ______________________________

Step 13 Test connectivity across the trunk

a. From enable mode on the switch, ping the router IP address for VLAN1 (the management

VLAN). Refer to IP Telephony Table 1 for this address. (X in the command below refers to the

pod number.)

CMESwitchX# ping 10.X.0.1

b. Was the ping successful from the switch? _____________________________________

If the ping was unsuccessful, do not proceed until appropriate troubleshooting has been performed and the ping is successful. Note that on some models of routers and switches the speed and duplex must be manually configured on both ports.

c. Ping the router IP address for the voice VLAN and the data VLAN. Refer to IP Telephony Table

1 for IP addresses, if necessary. All pings should be successful when the trunk is working correctly. Troubleshoot as necessary.

Step 14 Create VLANs on the switch

a. Manually create the data and voice VLANs in the VLAN database. The X in the VLAN number is

the pod number.

CMESwitchX# vlan database CMESwitchX(vlan)# vlan X0 CMESwitchX(vlan)# vlan X5 CMESwitchX(vlan)# exit

Step 15 Configure switch ports for IP phones

a. Cable the two IP phones to switch ports 4 and 6 using straight-through cables.

b. Configure the two IP phone ports to use the IEEE 802.1Q trunking protocol using the switchport

trunk encapsulation dot1q command. This command is executed from interface configuration

mode.

Note that the next step may have to be completed before this step if an older switch is being used.

Configure each switch port for the trunking encapsulation mode.

CMESwitchX(config)# interface fastethernet 0/4 (and 6) CMESwitchX(config-if)# switchport trunk encapsulation dot1q

c. Configure the two IP phone ports to be trunk ports with the switchport mode trunk command.

This command is executed from interface configuration mode.

CMESwitchX(config)# interface fastethernet 0/4 (and 6) CMESwitchX(config-if)# switchport mode trunk

d. For the ports that connect to the IP phones, the switch must be configured so that 802.1Q knows

which VLAN contains voice traffic. This is done with the switchport voice vlan command. The voice VLAN is X5, where X is the pod number. Refer to IP Telephony Table 1 for the IP addressing scheme.

CMESwitchX(config)# interface fastethernet 0/4 (and 6) CMESwitchX(config-if)# switchport voice vlan X5

e. The IP phone has a port used to connect a PC. The PC can (and should) be on a separate

VLAN from the IP phone. The IP phone connects to the switch via a trunk port. A trunk port can carry multiple VLAN information. In order for the phone to operate on a different VLAN from the

phone, the switchport trunk native vlan X0 (where X is the pod number) command must be

used. The native VLAN is the VLAN that does not get tagged with VLAN information as frames from this VLAN traverse the trunk. The native VLAN must be the same as the data VLAN for this to work.

This command is done in interface configuration mode. The interface to use is the switch interface to which one of the IP phones connects (the one that has a PC connected to the PC

port on the back of the IP phone). The X in the switchport command refers to the pod number.

CMESwitchX(config)# interface fastethernet 0/4 (and 6) CMESwitchX(config-if)# switchport trunk native vlan X0

The IP phones will not register at this point because Call Manager Express has not been configured on the router yet.

f. Save the switch configuration by typing the following command:

CMESwitchX# copy running-config startup-config

Note: Save the router and switch configurations to a text file as well. These configurations will be

required in future labs.

Lab 2.1.2 Installing Cisco CME Software

Objective

• Install Cisco CallManager Express (CME) software on the router

Equipment Requirements

• Cisco CallManager Express (CME) capable router

• Cisco router IOS version that supports CallManager Express

• Workstation with Ethernet 0/100 NIC installed

• TFTP server application

• Access to Table 1 IP Telephony IP Addressing Scheme and VLAN Assignment document

In this lab the ACME.com Company has configured the router with a basic configuration, but the version of IOS on the router does not support CallManager Express features. The version of IOS will need to be updated. The router should already be configured. Redo Lab 2.1.1 if necessary.

Note: This lab may not be necessary if the IPVoice IOS is already installed. Use the show flash:

command on the router and see if the words IPVOICE appear in the name of the IOS image. This is one quick indication that can be used to determine if this lab is necessary.

Step 1 Configure the TFTP server

Note: If the router has multiple Ethernet interfaces use the lowest numbered interface. For example, if

there are two Ethernet interface, 0 and 1, then 0 should be used.

a. Ensure the computer that has the TFTP server application loaded on it is connected to the

Ethernet port of the router. Be sure that the computer has an appropriate IP address and default gateway assigned. See the IP Telephony Table 1 for IP addressing assignment. An example IP address is 10.1.0.5 and default gateway of 10.1.0.1, where the 1 in the second octet is equal to the pod number and the number in the fourth octet is 2, 3 or any number between 5 and 254.

b. Ensure that the appropriate router IOS file that supports CallManager Express is placed in the

default folder for the TFTP server application. Obtain this file from the instructor.

c. Open the TFTP server application.

d. Console to the router. From the router ping the TFTP server. Do not proceed unless the ping is

successful. Troubleshoot as necessary.

e. What address is assigned to the TFTP server? ____________________________________

Step 2 Update and Install Cisco CallManager Express IOS

a. From enable mode, copy the IOS image from the TFTP server to the router. The prompts may

vary depending on the model and IOS.

CMERouterX# copy tftp: flash: Source filename? [Enter the IOS filename. It is best to copy and past the filename into this section.] Address or name of remote host? [Enter the address assigned to the TFTP server. See step 1e.] Destination filename? [The filename should be the same as what was placed in the source filename and Enter can be pressed.]

When and if prompted to overwrite enter y for yes.

(Address or name of remote host is the IP address of the TFTP server. Source filename is the filename of the Voice IOS located on the TFTP server. Destination filename is the same

name as Source filename. Contact the instructor to obtain the correct router IOS that supports IP Telephony.)

An example of the process follows:

CMERouter1# copy tftp flash:

Address or name of remote host? 10.10.0.12 Source filename? c2800nm-ipvoice-mz.123-11.T3.bin Destination filename? c2800nm-ipvoice-mz.123-11.T3.bin

Accessing tftp://10.10.0.12/ c2800nm-ipvoice-mz.123-11.T3.bin...

b. Was the TFTP transfer successful? _______________________

If not, troubleshoot until the transfer is successful. Do not proceed without a successful transfer.

c. Use the show flash command to verify that the IOS file is present in flash memory.

CMERouterX# show flash For example:

-#- --length-- -----date/time------ path 1 24119024 Mar 24 2005 22:17:00 +00:00 c2800nm-ipvoice-mz.123-

11.T3.bin 32143304 bytes available (24119024 bytes used)

d. The following are the steps to load new system IOS image:

CMERouterX# configure terminal CMERouterX(config)# boot system flash new_system_image_filename CMERouterX(config)# exit CMERouterX# copy running-config startup-config CMERouterX# reload

When prompted to save the system configuration, enter no. When prompted to confirm the reload, enter y.

e. Verify the system image file (IOS Image) is the correct one by using the show flash or show

version command. The system image file should match the filename used in step 2a.

CMERouterX# show version

For example: Cisco IOS Software, 2800 Software (C2800NM-IPVOICE-M), Version

Lab 2.1.3 Connecting the IP Phone to a Switch

Objective

• Connect an IP phone to a switch and provide power to it

Equipment Requirements

• Inline power capable switch or non-inline power switch with power injectors

• Two Cisco IP phones

This lab relies on labs 2.1.1 being successfully completed and loaded.

In this lab the ACME.com Company wishes to implement IP telephony. In order to do so, the phones must receive power in order to work.

• Cable the two IP phones to a switch

• Provide power to the phones using one or both methods

Step 1 Understanding the two types of switches

a. There are two types of switches that can be used with Cisco IP phones: (1) an inline power

switch and (2) a non-inline power switch. A switch that can provide power to another device such as an IP phone has the words INLINE POWER stenciled on it as shown below.

A non-inline power switch does not have the words INLINE POWER stenciled on it. An example of this type of switch is the 2950. The 2950 cannot provide power to other devices such as the Cisco IP phone.

b. Use the Cisco web site to determine if any model of 29xx switch can provide inline power.

Record the results. __________________________________________________________

Step 2 Cabling the IP phone to an inline power switch

Note: If an inline power switch is not available, skip to Step 3.

a. Locate the two RJ-45 ports on the back of the IP phone.

b. What are the names of the two RJ-45 ports? ______________________________________

c. Connect a power cord to the switch that is to provide the inline power. The switch should power

on.

d. Connect a straight-through Ethernet cable from the 10/100 SW port on the IP phone to any 100

MB port on the inline power switch.

e. What indication is shown that the phone is receiving power? _________________________

__________________________________________________________________________

Step 3 Cabling the IP phone to a non-inline power switch

a. Connect power to the non-inline power switch.

b. In order to connect a Cisco IP phone to a non-inline power switch, a power injector is needed.

Look at the power injector and notice the two RJ-45 jacks on one end of the power injector.

The port on the left labeled 10/100BaseTX to Device is used to connect to the IP phone (via a straight-through cable).The port on the right labeled 10/100BaseTX to Network is used to connect to a non-inline power switch such as a 2950 switch (via a straight-through cable).

c. Connect a straight-through cable from the left power injector port labeled 10/100BaseTX To

Device to the IP phone port labeled 10/100 SW.

d. Connect a second straight-through cable from the right power injector port labeled

10/100BaseTX To Network to any non-inline power switch port.

e. At the opposite end of the power injector module there is a cable that goes to the power supply

adapter. The opposite end of the power supply adapter requires an AC power cord.

Plug an AC power cord into the AC adapter. Plug the other end of the AC power cord into an AC wall outlet.

f. What indication is shown on the phone that power has been applied?

______________________________________________________________________________ _______________________

Answers to 2.1.3 Lab

1b. At the time this lab was written, the 2970 was the most powerful 29xx series switch and it does not support inline power for all of its ports.

2b. 10/100 SW and 10/100 PC

2e. The phone starts displaying words on the screen. Also, when power is first applied, the buttons on the bottom start lighting up sequentially.

3f. The phone starts displaying words on the screen. Also, when power is first applied, the buttons on the bottom start lighting up sequentially.

Lab 2.1.4 Resetting a 7900 Series Cisco IP Phone to Factory Defaults

Objective

• Erase the current configuration from an IP phone

Equipment Requirements

In this lab, the ACME.com Company has decided to deploy CallManager Express (CME) in the enterprise. First, the IP phones must be reset. They were used in a test lab by the network support staff and currently have various configurations. This process should be used when configuring any IP phone that could have been previously configured.

Step 1 Provide power to the switch

a. Cable the Cisco IP phone to an inline power switch using a straight-through cable OR cable the

phone (with a straight-through cable) to a power module that connects to a non-inline power switch.

b. Power on the switch.

c. Which method of providing power to the IP phone was chosen? __________________________

d. What is an advantage of using an in-line power switch? ________________________________
