Switch Cisco with Call Manager 4.1

[jmuro]

Hi , i ha a call manage connected to Switch 3560, my configuration ports are:

interface FastEthernet0/1X
switchport trunk encapsulation dot1q
switchport trunk native vlan 4
switchport mode trunk
switchport voice vlan 6
spanning-tree portfast


all works fine, but now i must connect another switch to my 3560.

how can i connect another switch, without lost my configuration?

If you are going to have IP phones on the second switch ie. Cisco 3560,
interface FastEthernet0/1X
switchport trunk encapsulation dot1q
switchport mode trunk
On both ends of the connection.
If it is a pure data switch
interface FastEthernet0/1X
switchport access vlan 4
On the Cisco 3560 port.

I would also add 'auto qos voip cisco-phone' to your voice ports.

Read the QoS SRND on CCO (

http://www.cisco.com/go/srnd)....

You don't need to configure you access ports as VLAN trunks. Since IOS 12.1 on the 2950 & later you just configure your switchports as access ports:

interface FastEthernet0/x
 switchport access vlan 4
 switchport mode access
 switchport voice vlan 6
 priority-queue out 
 spanning-tree portfast
!

If you intend to use the same Access & Voice VLAN's on the 2nd switch then you need to create a trunk. The current recommended configuration on either end would be:

interface GigabitEthernet0/x
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 4000
 switchport trunk allowed vlan 4,6
 switchport mode trunk
 switchport nonegotiate

QoS is another issue altogether so I suggest you read the QoS SRND.
