ISR 4331 (Voice and Data)

[GW M]

I have an ISR 4331 and I would like to configure a voice and data VLAN on it's layer 3 interface that connects to a layer 2 switch. Which option is correct?

Option 1:

vlan 100
name Data
!
vlan 111
name Voice

!

interface GigabitEthernet0/0/1
description Inside LAN Interface
switchport mode access
switchport access vlan 100,111
speed 1000
duplex full

!

interface vlan 100
description Inside LAN vlan
ip address 192.168.0.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
!
interface vlan 111
description Voice vlan
ip address 10.168.11.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp

Option 2:

vlan 100
name Data
!
vlan 111
name Voice

!

interface GigabitEthernet0/0/1
description Inside LAN Interface
switchport native vlan 100
switchport mode trunk
switchport trunk allowed vlan 100,111
speed 1000
duplex full

!

interface vlan 100
description Inside LAN vlan
ip address 192.168.0.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
!
interface vlan 111
description Voice vlan
ip address 10.168.11.1 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp

Thanks

In ISR if you have 2 Interface, i prefer to use port-channel with Switch, so you have redundent link available in case one port go down due to some reason.

Agree.. but what is the preferred option as far as trunking data and voice on the port versus making it an access port with a data and voice vlan?

Trunking is my preference.
