Hello, I feel stuck trying to configure our SG350-28P. My SG350-28P is connected to our
However, I cannot seem to figure out how to configure my switch so that I can connect a Cisco Phone (8945) and have a desktop plugged into the phone. The data
On all of my other switches (Cisco 2960 or Cisco 3560), I would just issue the following:
But with the 350 those commands do not work. I've tried messing with the "Smart Port" feature but I'm not sure it is working as I understand it should.
Here's my current switch config:

Matthew, I am a Cisco Engineer from the Small Business department.
I am afraid that your issue could be related to the Auto Smartport configuration. If you are planning to manually setup the ports configuration, the Auto Smartport must be disabled.
* Let's suppose that you are using port 3 to connect the Cisco Phone -> Desktop.
1- Interface Settings > The interface VLAN Mode needs to be setup as trunk (because you are going to joining more than 1 VLAN)
2- port VLAN Membership > The Administrative VLANs should be 2UP, 100T.
3- If your Datacenter 3560x is your DHCP server it needs to be joining also these VLANs.
Do not hesitate to let me know if you have more questions.

Do I need to disable the Auto Smartport config on the port or the entire switch?

You can try disabling only the port for testing porpuses. Then if you need to disable it from the entire switch you can do it.
Notice that if you disable/enable the Auto Smartport feature for the entire switch, the configuration on the ports is deleted.

How do I get vlan2 to show as UP? Right now it only shows as U.

Try enabling this from the Port to VLAN instead of Port VLAN Membership Table.

ok, in my screen there the checkbox is greyed out on that port and already checked. I cannot un-check it or re-check it.

Hello Ingrid ,
I have same problem only with SG350 . As i am using SG200 and SG300 in many locations and they worked fine , but i have bought new SG250 and some SG350 (because SG200 & SG300 End of Life) . I have placed SG250 on one of my location but the problem is both VLAN not works at the same time . I have the same topology which you had mention .
In SG300 the both VLAN works fine i am attaching a picture with this message but SG250 is not . I have did the same configuration i did it SG300 but in Sh Running Config it shows little bit weird . I request you please check my config and reply with a solution because we are going to order 36 SG350 for different locations.

Hello All,
Happy New 2019 Year!
First download the CLI guide:
You have 2 options:
smartport (starting on page 1066)
or
You need to make all the ports with phones and desktop in switchport mode trunk, change native VLAN and add voice VLAN to the trunk (page 1266):
switchxxxxxx(config)# interface gi11 switchxxxxxx(config-if)# switchport mode trunk switchxxxxxx(config-if)# switchport trunk native vlan 2 switchxxxxxx(config-if)# switchport trunk allowed vlan add 100
Hope it helps
Cheers,
Mike
