My name is Ismael. Iam with Small Business Support Center. From my understanding you are passing DATA on vlan 5 and VOICE on vlan 10. Also your voip phones are connected to a Cisco 3560. What is the management vlan or native? That vlan would be untagged under your uplink. In your case like you have described your uplink would be trunked and then you would tag vlan 5,10. Let me know if you need more details.
Thanks for your kind reply ismail,
As I mentioned early we have 3 switch here
One is master switch which all network connected and also data van using in this switch. Excluding voice. For here one uplink is going to our smb switch. I made this port trunk and allowed van 5.
Other switch is only for voice which not connected in master switch. Here interface vlan is 10.10.10.250 . And from this range up using for ip communication manager. But for voice we mentioned vlan 10 In this switch. For here one uplink is going to the smb switch for passing voice vlan 10. Put a uplink to the smb switch and made this port trunk and allowed vlan 10. So our smb switch should learn both vlan firm 2 up links right. Correct me if am wrong.
But our smb switch not giving either voice or data to the end user.
