This Packard Tracer Lab consists of Cisco IP phones and PCs.
In addition, it consists of a Cisco switch and a Cisco router.
You need to configure the router as a router on a stick to enable IP connectivity between multiple VLANs
in this topology as well as configure the router as a call manage express router or Cisco Unified Communications
Manager Express Router.
The switch is going to act as a Layer two switch, but you need to configure the switch with both a
voice VLAN and a data VLAN.
So there are a number of things that you need to do to get this network working.
You're going to need to configure the broader with IP addresses for VLAN one, VLAN 100 and VLAN 101.
You need to configure the router as a router on a stick to route between those vlans.
You need to configure the router with two DHCP pools, one for the data VLAN or PCs and one for the
voice of LAN or phones.
You can use any DHCP pool name that you want, but make sure that PCs are getting IP addresses in this
range through DHCP and phones are getting IP addresses in this range via DHCP.
With the router acting as a DHCP server, the PCs are going to be configured in VLAN 100 subnet ten
one 100 zero 24.
The router will be the default gateway as well as the DNS server for the PCs.
The phones are going to be in subnet ten 11010 slash 24.
In other words, in VLAN 101 default gateway will be the router and option 150.
In other words, TFTP will be configured as the router.
The router is going to be configured as the TFTP server because the IP phones will get their configuration
from the router.
You again need to configure the switch with both voice and data VLANs and configure the switch as a
layer to switch.
With this IP address and the default gateway being the router, he has a basic configuration for Cisco
Unified Communications Manager Express or CME or Call Manage Express as it used to be known.
In global configuration mode, you going to enable the telephony service and then you need to specify
the max number of phones and max a number of d n or directory numbers that the router will support.
We're going to set both of those to three.
To keep it simple, you could make it more if you wanted to.
The router is going to be listening on this IP address for skinny messages from the phones.
Skinny or CCP or skinny client control protocol.
Is the protocol used between.
IP phones and Cisco communication servers for call setup configuration and other options.
So this is the IP address of the router on the voice of VLAN and the route is going to be listening
on port 2000.
That's similar in concept to enabling a web server on Port 80.
We're going to order a sign directory numbers 1 to 3 to phones that register.
So we're going to create three iPhone DNS, all three iPhone directory numbers, telephone numbers that
will be assigned to the phones, 1000, 1001 and 1002.
We are automatically going to assign iPhones to the IP phones that register when a new phone registers.
We want to assign iPhone one to the first phone, iPhone two to the second phone, iPhone three to the
third phone.
When things are working properly, you'll see the Mac address of the phone associated with the iPhone.
Now, you could manually configure the MAC addresses with the phones if you wanted to, but we're not
going to do that here.
We're going to allow the phones to automatically register.
Button one is saying that extension one on the phone will be assigned telephone number one.
In other words, 1000.
So on a phone such as a 79, 60, you can have up to six telephone numbers configured on the phone.
But all we're going to do is configure the primary or first extension.
So button one, the stop button will be configured to watch telephone number one.
We'll do something similar on the other phones.
Button one on the second phone will be assigned telephone number 1001 because it's configured on iPhone
D and two iPhone three button one top button on the phone is going to have extension number 1002.
If the router doesn't accept these commands.
So it doesn't accept a button one colon, one or button one colon two or button one colon three, type
the commands once the phones have registered.
Now as a verification for this lab, verify firstly that the phones are getting power from the switch.
We're going to be using inline power to verify that the phones are visible via CDP, make sure that
the phones can call each other and make sure that the PC can ping the switch and the IP phones.
So check that you have connectivity in your network.
Check that the phones can call each other, basically ensure that the network is working.
So can you complete this lab?
Download the attach to packet, trace a file and see if you can complete the lab yourself.
Otherwise, watch the next video where I complete the lab.
