CBS350 - VLAN and Yealink OUI

[GDoggy]

I've just purchased a CBS350-48T-4X - my first fully managed switch so I'm using the web GUI.

I'm trying to set up a VLAN for our voice traffic.

VLAN1 obtains an IP address from a DrayTek router - used for broadband access

VLAN20 obtains an IP address from a BT router - used for SIP cloud service

I'm trying to get some Yealink phones to join VLAN20 using the "Telephony OUI" settings.

I've added the Yealink manufacturer code to the OUI table, added the ports to the Telephony OUI Interface and enabled Telephony OUI.

When I connect the phones, they are still obtaining an IP address from VLAN1.

Am I missing something or is there a posible compatiblity issue with the types of phones we are using?

LLDP-MED is activated on the Yealink Phones?

[GDoggy]

Hi.

Yes LLDP is enabled on the phones.

LLDP or LLDP-MED?

[GDoggy]

There's only an option to enable / disable LLDP but the user manual says "The DECT IP phones support Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED)"...

Captured initial broadcast from one of the devices using wireshark:

Destination: LLDP_Multicast (01:80:c2:XX:XX:XX)
    Address: LLDP_Multicast (01:80:c2:XX:XX:XX)
    .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default)
    .... ...1 .... .... .... .... = IG bit: Group address (multicast/broadcast)

Source: YealinkX_XX:XX:XX (80:5e:c0:XX:XX:XX)
    Address: YealinkX_XX:XX:XX (80:5e:c0:XX:XX:XX)
    .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default)
    .... ...0 .... .... .... .... = IG bit: Individual address (unicast)

Type: 802.1 Link Layer Discovery Protocol (LLDP) (0x88cc)

Were you able to get that feature working?
