Current Cisco Configuration

Interface FastEthernet0/1

Description data & Phone

Switchport access vlan 60

switch mode access

swicthport voice vlan 888

spanning tree portfast

 

I have configured the extreme for voice to be tagged and data to be untagged.

When the phones connect they are connecting on teh data vlan and not voice .. so if I look at teh fdb for the port I have both macs on the data vlan ,,, incidently the phone actually works ..

LLDP is enabled,

configure lldp port 1:6 advertise system-name
configure lldp port 1:6 advertise vendor-specific dot1 vlan-name vlan VOICE-1

configure lldp port 1:6 advertise vendor-specific med capabilities
configure lldp port 1:6 advertose vendor specific power-via-mdi
confgure  lldp port 1:6 advertise vendor-specific med policy application voice vlan VOICE dscp 46

With this configuration , the Polycom phones still boot onto the data vlan ..

 

HAve I missed anything ?

Doi I need to modify the dhcp options on teh DAta vlan ..

Hi , thanks for all the advice , in teh end teh customer was moving to “ soft phone” so the issue with the polycom phones went away .. they were definatly both untagged so teh only way I could have supported this configuration was in effect changing teh ethernet type , for one of the vlans, then I understand you can have multiple untagged vlans on same port .. so thanks for your advice and help

My first guesses would be either the Voice VLAN is not properly tagged on the port, or the phone is sending out untagged frames. I don’t think LLDP should be impacting your VLAN assignments, that should just advertise the phones capabilities.
