* If telnet is unable to connect to the router the router may not have been reset properly by the previous user and you will have to connect directly to the router using a console cable. If you do not know how to do this please ask your instructor. Authors: Mary Hawkins & Patrick Neff - 2006 Page 6 of 21
Office A (Diagram on page 18) Office A is a wired computer network office. It is using a gigabit Ethernet switch for connectivity between the computers in the office. The office is connected to the other offices by a router that is directly connected to the switch. This router is connected to the core router, which is connected to the other offices. The following are the basic setup configurations and commands used to set up and run this office. At the computer (needs active internet connection to access switch): Open up a web browser and type 172.16.1.6 in the address bar to access switch Username is GigEwire, password is convergige Go to the CMS (You may have to download the software.

Office C (Diagram on page 20) VOIP/POTS Setup Office C will have VoIP for its phone service. VoIP phones and analog phones will be used in the office. All VoIP phones will have their phone numbers and IP addresses given to them by the router, which will be running Cisco CallManager Express. Analog phones will have their phone numbers manually configured in the router. Initial router setup (skip if the router is running default configurations): Router# delete flash:vlan.dat Router# erase startup-config Router# reload Router(config)# hostname Router6 Router6(config)# no ip domain-lookup Router6 (config)# line vty 0 4 Router6 (config-line)# password cisco Router6 (config-line)# login Router6 (config-line)# logging synchronous Router6 (config)# line console 0 Router6 (config-line)# password cisco Router6 (config-line)# login Router6 (config-line)# logging synchronous Setting up VoIP: Router6# vlan database Router6 (vlan)# vlan 40 name Data state active Router6 (vlan)# vlan 45 name Voice state active Router6 (config)# interface vlan 1 Router6 (config-if)# ip address 10.4.0.1 255.255.255.0 Router6 (config-if)# no shutdown Router6 (config)# interface vlan 40 Router6 (config-if)# ip address 10.40.0.1 255.255.255.0 Router6 (config-if)# no shutdown Router6 (config)# interface vlan 45 Router6 (config-if)# ip address 10.45.0.1 255.255.255.0 Router6 (config-if)# no shutdown Setting up the two VoIP phone ports to be used: Router6 (config)# interface fastethernet slot/port-adapter/port Router6 (config-if)# switchport trunk encapsulation dot1q Router6 (config-if)# switchport trunk native vlan 40 Router6 (config-if)# switchport mode trunk Router6 (config-if)# switchport voice vlan 45 Router6 (config-if)# no shutdown Router6 (config)# interface fastethernet slot/port-adapter/port Router6 (config-if)# switchport trunk encapsulation dot1q Router6 (config-if)# switchport trunk native vlan 40 Router6 (config-if)# switchport mode trunk Router6 (config-if)# switchport voice vlan 45 Authors: Mary Hawkins & Patrick Neff - 2006 Page 10 of 21

The IP network of the DHCP pool for voice devices is 10.45.0.0. e. The subnet mask for the DHCP network is 255.255.255.0. f. The TFTP server IP address will be the Cisco CallManager Express router with an IP address of 10.45.0.1. Option 150 is an optional DHCP option which allows the IP telephony device to obtain configuration information (files) from the TFTP server. g. The default router for the pool will also be 10.45.0.1. h. Answer yes to the question regarding starting the telephony service setup. i. For the source IP address, enter 10.45.0.1. j. Accept the default port of 2000 by pressing the Enter key. k. When asked how many phones to configure, respond with 4. l. When asked whether dual-lines are desired, answer y, and press Enter. m. Select the language that is desired on the phone. (The default of English may be accepted by simply pressing the Enter key.) n. Select the country for call progress tones. (If in the United States, the default may be used by just pressing the Enter key.) o. Enter first extension number, which is 5000. p. When asked if DID (Direct-Inward-Dialing) is used, answer y, and press Enter. DID is a local phone company service that provides a block of phone numbers used to call into a company's PBX system. With DID, individual phone numbers can be assigned to each person or PC without having to have a physical line into the PBX for each person s connection. q. When asked for the full E.164 number, enter 5105555000. A fully qualified E.164 number contains a country code (issued by the ITU), area code (sometimes known as a STD code), and the local telephone number. r. When asked if forwarding to voicemail (voice message service) is desired, enter y, and press Enter. s. Enter the extension number 555028 for voicemail. t. Press the Enter key to accept the default of 18 seconds for Call Forward timeout. Authors: Mary Hawkins & Patrick Neff - 2006 Page 11 of 21
u. When asked if any of the information is to be changed, select yes to change an option, or no to use the current settings and to exit out of the utility. If no mistakes were made in the previous steps enter n, press Enter, and proceed to the Step1 v. If any mistakes were made enter y, press Enter, and go back to Step 1c. v. Watch the console output to see if the phones register. Setup of DHCP to automatically give IP addresses to the phones: Router6 (config)# ip dhcp pool DATA Router6 (dhcp-config)# network 10.40.0.0 255.255.255.0 Router6 (dhcp-config)# default-router 10.40.0.1 Router6(config)# ip dhcp excluded-address 10.40.0.1 10.40.0.10 Setup of the analog phones: Find out the analog port numbers with the following command.
