Sample configuration for Voice and Data deployment on a Switch



Case 1: Phone and PC's on different/dedicated switch ports on the switch



Creating VLAN's


Voice VLAN


Switch#conf t

Switch(config)#vlan <VLAN ID>

Switch(config-vlan)#name Voice - description of the VLAN


Similarly for the Data VLAN



Creating VLAN interfaces (SVI's) and assigning IP address to them:


Switch#conf t

Switch(config)#interface vlan <VLAN ID>

Switch(config-if)#ip address <X.X.X.X> <X.X.X.X> - IP address Subnet Mask

(The ip address should be one of the useable IP addresses of the phone or data subnet)


Similarly for the Data VLAN



Interface configuration - Data/Voice


Switch#conf t

Switch(config)#interface GigabitEthernet <interface ID>

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan <VLAN ID> - data VLAN in case of PC

or

Switch(config-if)#switchport voice vlan <VLAN ID> - Voice VLAN in case of phone


If QOS is to be applied


Switch(config)#mls qos - Enabline QOS globally on the switch


Switch(config)#interface GigabitEthernet <interface ID>

Switch(config-if)#auto qos voip trust



Case 2: PC's connected via switchport behind the IP phone.



Creating VLAN's


Voice VLAN


Switch#conf t

Switch(config)#vlan <VLAN ID>

Switch(config-vlan)#name Voice - description of the VLAN


Similarly for the Data VLAN



Creating VLAN interfaces (SVI's) and assigning IP address to them:


Switch#conf t

Switch(config)#interface vlan <VLAN ID>

Switch(config-if)#ip address <X.X.X.X> <X.X.X.X> - IP address Subnet Mask

(The ip address should be one of the useable IP addresses of the phone or data subnet)


Similarly for the Data VLAN



Interface configuration - Data/Voice


Switch#conf t

Switch(config)#interface GigabitEthernet <interface ID>

Switch(config-if)#switchport trunk encapsulation dot1q

Switch(config-if)#switchport mode trunk

Switch(config-if)#switchport trunk native vlan <VLAN ID> - Data VLAN

Switch(config-if)#switchport access vlan <VLAN ID> - Voice VLAN



OR


Switch#conf t

Switch(config)#interface GigabitEthernet <interface ID>

Switch(config-if)#switchport trunk encapsulation dot1q

Switch(config-if)#switchport mode access

Switch(config-if)#switchport voice vlan <Voice VLAN ID>

Switch(config-if)#switchport access vlan <VLAN ID>


  • With newer IOS it is not required that a switchport connecting a phone piggybacking a PC to be configured as a trunk specifically. Please see the secondary configuration above.




If QOS is to be applied


Switch(config)#mls qos - Enabline QOS globally on the switch


Switch(config)#interface GigabitEthernet <interface ID>

Switch(config-if)#auto qos voip trust

Or

Switch(config-if)#auto qos voip trust cisco-phone (specifically for Cisco IP phones)

Note: The above mentioned commands are version specific, however are same or similar in most of the cases.
