Hello,
I'm having trouble splitting voip traffic from the data traffic. I am using a 5505 asa and 3560 switches
ASA 5505 > catalyst 3560 > IP phone > laptop
on the ASA 5505
------------------------
I configured 4 Vlan's
1 for management
1 for outside
interface Vlan200 (data)
nameif Inside
security-level 100
ip address 10.0.31.15 255.255.255.0
!
interface Vlan400 (voice)
nameif VOIP
security-level 100
ip address 10.20.31.15 255.255.255.0
I configured one trunk port on a non-POE port 0/2
interface Ethernet0/2
description Trunk port to SW1
switchport access vlan 400
switchport trunk allowed vlan 200,400
switchport trunk native vlan 200
switchport mode trunk
On the 3560 switch
I configured one trunk on a POE port that connects to the ASA 5505
switchport trunk encapsulation dot1q
switchport trunk native vlan 200
switchport trunk allowed vlan 200,400
switchport mode trunk
I configured another POE port where I m connecting the IP phone (Cisco 7940 or Polycom soundpoint 501)
description Trunk port IPTEL_DATA
switchport access vlan 200
switchport mode access
switchport voice vlan 400
When connecting the IP phone to that port and connecting a laptop on the phone's switch port, the phone and PC get the correct Vlan and IP assigned but I'm not able to register the phone with our provider.
When connecting the IP phone directly on a different port on the ASA 5505 (default vlan 1) The phone immediately gets the config file and registers.
Did I trunk correctly using trunk mode for the asa 5505 to catalyst3560 and access mode for the catalyst3560 to ip-phone?
Any help is more than welcome
