Auto Voice VLAN vs OUI Table + Voice VLAN port CFG

[bl1nd3d]

Hello everyone,

our company is about to finally implement their first VoIP system.

We are using Cisco SB SG350X for LAN connectivity.

As far as I've learned, I have to decide wether to use Auto-Voice-VLAN with Auto-Smartports (AVV) or OUI-tables to use voice VLANs at all. Correct?

If I want to use AVV, phones need to support LLDP. If they don't, I have to use the OUI-table, right?

One further question:

Client PCs will be connected to phones and phones are connected to switches.

I've configured all switch ports to be trunk-ports.

For Catalyst-switches u can simply use the voice vlan command to configure the port. But SB is different.

Is there any need to allow a further VLAN on the trunk port or can I just leave like this?

interface GigabitEthernet1/0/1
spanning-tree portfast
switchport mode trunk

The native VLAN for the clients is 1 and the voice VLAN should be detected by AVV, right?

Thanks for your help :)

You can try the below.

port which you connect the phone, voice vlan should be tagged and data vlan as untagged.

Hello Nithin,

thanks for your reply :) 

As VLAN 1 is always untagged and VLAN 1105 (my Voice VLAN) is automatically tagged at all ports (checked in in the UI), my config should be working :)
