How to configure VoIp phone and use the second port to connect PC?

---

I am a bit confused if i should tag the Vlan or just use the command Voice Vlan name,,,,

@Yihad-Fadlallah-0,

So physically, the Switch connect to the phone, the worstation connects to the phone.

ON the switchport you configure both

SW1(config)#vlan 100
SW1(config-vlan)#name Data
SW1(config-vlan)#exit

SW1(config)#vlan 110
SW1(config-vlan)#name Voice
SW1(config-vlan)#exit

SW1(config)#interface GigabitEthernet 0/1
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 100
SW1(config-if)#switchport voice vlan 110
SW1(config-if)#exit

This also depends on the VoIP phones you're using. Here's what is a general guideline:

• Voice VLANs - Cisco phones
• Vlan - Other VoIP phones

This has to with the fact that not all VoIP phone recognized voice VLANs. But Cisco VoIP phones I know will use them.

SW1(config-if)#switchport access vlan 100
SW1(config-if)#switchport voice vlan 110
SW1(config-if)#exit

I see so with this command SW1(config-if)#switchport voice vlan 110 will work for every voip phone not cisco, right?

Thanks for your answer.

@Yihad-Fadlallah-0,

voice vlans will work for Cisco Phones

other phones, unless specified will use tagging.

So in this instance, switchport voice vlans 110 will work for Cisco Phones...rather than other VoIP phones.

@Ronnie-Wong Can you provide me an example for other phones using the vlan tag to connect a pc in to phone port.?

@Yihad-Fadlallah-0,

The pc would connect to a port on the phone usually labeled for PC (or at least a graphic representation). Then the Phone also has a LAN port on the phone too. the LAN connects to the switch. Then depended on the switch itself, it could be that the phone can trunk to the switch, with phone and pc on 2 different vlans.

Cisco phones do not need the trunk because of the ability of the voice vlan and data vlan do not have to be carried across a trunk to make it work.
