!!!I used real Cisco 3550 switch *4 to do this lab. I did not use Dynamips to do this lab.!!!
Objective:
‧ Configure auto QoS to support IP phones
‧ Configure CoS override for data frames
‧ Configure the distribution layer to trust access layer QoS measures
‧ Manually configure CoS for devices that cannot specify CoS (camera)
‧ Configure HSRP for voice and data VLANS to ensure redundancy
‧ Configure 802.1Q trunks and EtherChannels for Layer 2 redundancy and load balancing
Scenario:
You must configure the access and distribution layer switches to trust the CoS
mapping provided by the IP phone through Cisco Discovery Protocol (CDP).It is not
necessary to have a camera to successfully complete the lab.
Basic Configuration:
All Switches:
enable
configure terminal
!
no ip domain lookup
!
line console 0
logging synchronous
exec-timeout 0 0
!
hostname
Step 1
Start by deleting the vlan.dat file, erasing the startup config, and reloading all your switches.
All Switches:
Clearing all Switches
Step 2
Configure management IP addresses in VLAN 1, hostname, password, and
telnet access on all four switches.

ALS2(config)#interface vlan 1
ALS2(config-if)#ip address 172.16.1.102 255.255.255.0

Configure default gateways on the access layer switches.
ALS1(config)#ip default-gateway 172.16.1.1
ALS2(config)#ip default-gateway 172.16.1.1
Step 3
Configure the trunks according to the diagram, and configure EtherChannels
between the switches. Using EtherChannel for the trunks provides Layer 2 load
balancing over redundant trunks.

Step 4
Change the VTP mode of ALS1 and ALS2 to client.
ALS1(config)#vtp mode client
ALS2(config)#vtp mode client

ALS2#
Step 5
Create the VTP domain on DLS1, and create VLANs 100 and 200 for the
computer data and voice VLANs in the domain.
DLS1(config)#vtp domain SWPOD
DLS1(config)#vlan 100
DLS1(config-vlan)#name CP-Data
DLS1(config-vlan)#exit
DLS1(config)#vlan 200
DLS1(config-vlan)#name Voice
DLS1(config-vlan)#exit
Step 6
Configure Hot Standby Router Protocol (HSRP) between the VLANs to provide
redundancy in the network. Use the ip routing command on DLS1 and DLS2 to
activate routing capabilities on the switch. Notice in the following
configurations that the priority for VLANs 1 and 100 has been configured for
150 on DLS1, making DLS1 the active router for those VLANs. VLAN 200 has
been configured for a priority of 100 on DLS1, making DLS1 the standby router
for this VLAN. Reverse priorities have been configured on the VLANs on DLS2.
DLS1(config)#ip routing
DLS1(config)#interface vlan 1
DLS1(config-if)#standby 1 ip 172.16.1.1
DLS1(config-if)#standby 1 preempt

DLS1#
Step 7
Configure Fast Ethernet access ports 15 to 24 to trust the CoS for recognized
IP phones on the network. Any port that has a device other than a Cisco phone
will not trust the CoS that is advertised.
ALS1(config)#interface range fastEthernet 0/15 - 24
ALS1(config-if-range)#switchport access vlan 100
ALS1(config-if-range)#switchport voice vlan 200
ALS1(config-if-range)#auto qos voip cisco-phone
ALS2(config)#interface range fastEthernet 0/15 - 24
ALS2(config-if-range)#switchport access vlan 100
ALS2(config-if-range)#switchport voice vlan 200
ALS2(config-if-range)#auto qos voip cisco-phone
Step 8
Verify the auto QoS configuration at the access layer.
ALS1#show mls qos interface fastEthernet 0/15

Step 9
Configure the distribution layer switches to trust the CoS information in the
Layer 2 frames being sent from the access layer.
DLS1(config)#mls qos
DLS1(config)#interface range fastEthernet 0/7 - 12
DLS1(config-if-range)#auto qos voip trust
DLS2(config)#mls qos
DLS2(config)#interface range fastEthernet 0/7 - 12
DLS2(config-if-range)#auto qos voip trust
Step 10
Verify auto QoS at the distribution layer on DLS1 and DLS2.

Step 11
A camera needs to be moved from its current location in the network and
connected to FastEthernet0/5 of ALS2. Assign a CoS of 3 to ensure that
the video traffic is identified by other switches and routers within the network.
ALS2(config)#interface fastEthernet 0/5
