Switch QoS, VTP, Etherchannel, and General Config

Hello,

I'm replacing a 2960g with a 2960s and would like to verifiy that QoS, VTP, Etherchannel and the general config is configured correctly. I copied the QoS config lines from one of our 3560 switches(See attached) which has Mitel IP phones connected and working fine. Will QoS work correctly on the 2960s?

I also had troubles with command "switchport trunk encapsulation dot1q" which I also copied from one of the 3560's. Setting the port to "switchport trunk" is not a problem, but the command would fail at "encapsulation dot1q". Is there something that I'm missing or is this new to the 2960s? Is  "encapsulation dot1q" not necessary, or is there a better way to configure the voice ports?

2960s

interface GigabitEthernet1/0/1
switchport voice vlan 2
priority-queue out
mls qos trust cos
spanning-tree portfast

3560

interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport voice vlan 2
priority-queue out
mls qos trust cos
spanning-tree portfast

If someone could verify that when I take out the 2960g and put in the 2960s that everything will work, I would appreciate it.

All configs are attached.

Let me know if you need more explanation.

Thanks.

The 2960 series ONLY supports dot1q, that is why the command to enable it is not supported (its the only optionJ) In other words ISL isn’t supported.

Do I need to specifiy another command so the port will know that it's a trunk and the IP phones will connect to the proper vlan?

Would "switchport mode trunk" work, or is there a better command?

You can trunk the interface (hence the whole discussion of dot1q) but before we get into it, I am familiar with Cisco phones, so I’m not going to go into a long winded explanation of the options for Cisco phones. Here is a Shoretel best practice doc when you using Cisco switches with Shoretel gear. I would assume this would be your best bet.

Sorry i responed so quickly I didnt see the Shortel part at first.
