Need help on VVID

[vidirk]

I have a Catalyst 3524XL Inline Power. The default VLAN is 1 and that is the VLAN for the IP Phones and the CCM. VLAN 120 is the VLAN for the workstations.

I have been trying to configure the switch so i am able to use the same port for the phone and the workstation. I have followed the documentation on http://www.cisco.com/warp/public/cc/pd/si/casi/ca3500xl/prodlit/cfig3_an.htm

but with no luck

Here is the config of the port:

interface FastEthernet0/1

switchport trunk encapsulation dot1q

switchport multi vlan 1,120

switchport mode trunk

switchport voice vlan 1

Int fa0/24 is a trunk to another switch.

Here are the VLANS:

VLAN Name Status Ports

---- -------------------------------- --------- -------------------------------

1 default active Fa0/2, Fa0/3, Fa0/4, Fa0/5,

Fa0/6, Fa0/7, Fa0/8, Fa0/9,

Fa0/10, Fa0/11, Fa0/12, Fa0/13,

Fa0/14, Fa0/15, Fa0/16, Fa0/17,

Fa0/18, Fa0/19, Fa0/20, Fa0/21,

Fa0/22, Fa0/23, Gi0/1, Gi0/2

115 VLAN0115 active

120 VLAN0120 active

213 VLAN0213 active

255 VLAN0255 active

1002 fddi-default active

1003 token-ring-default active

1004 fddinet-default active

1005 trnet-default active

Thanks in advance

The example link you referenced assumes that you're going to use vlan 1 for data and something else for voice. So try this on your 3524 & see if it works...

int fa 0/1

switchport trunk encap dot1q

switchport access vlan 120

switchport voice vlan 1

switchport mode trunk

What you are missing is the native vlan. I have pasted a working example that I use:

VLAN1 is my management vlan (10.4.66.0/26)

VLAN4 is my voice vlan (10.40.4.0/22)

VLAN81 is my data vlan (10.4.81.0/24)

All 24 FE ports can be used for Phones with PC or just a PC. The GE ports are used for uplinks.

interface FastEthernet0/1

switchport trunk encapsulation dot1q

switchport trunk native vlan 81

switchport mode trunk

switchport voice vlan 4

switchport priority extend cos 0

spanning-tree portfast

interface GigabitEthernet0/1

description Uplink to PWAMatherW2SW3

switchport mode trunk

interface VLAN1

ip address 10.4.66.52 255.255.255.192

Hi,

Thanks for your reply.

Thomas this was the line that was missing in my config. Now it´s working great.

'switchport trunk native vlan 120'

Thank you very much for your help :-)
