Convert csico switch voice and data configuration to Extreme X440-G2

[Rod_Robertson]

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 ..

Rod,

This is Cisco specific but this can be done also on other equipments.

Anyway, check the lldp config as mention by Christopher and also check the config of the IP Phone to ensure that lldp is enabled. It is usually by default but I’ve seen some IP Phones with lldp disabled by default.

please attach also the output of the fllowing command:

show lldp neighbors detailed

show lldp detailed ports 1:6

Hi Rod,

Can you attach the output of the following commands:

show vlan
show conf lldp | i 1:6

Thanks,

Hi went on site again today , and first tried Christophers suggestion, that does not work , the phone do not seem to understand Tag .. as If I connect as untagged in Voice then it all works as expected .

So basaically the phones work , untagged … so a cisco expertout there , what is the difference that they can run two untagged vlans on the same port , as per my original post .. or is this a cisco specific frig.. ( fix )

Thanks so far for your help

Rod,

In your config you mention VOICE and VOICE-1, I think it should twice the same

Check if you polycom firmwares supports the LLDP-MED and double check the release notes. I’ve experienced some issues with old firmwares and LLDP-MED.

I use this with the voice VLAN tagged and the data VLAN untagged:

configure lldp port 1 advertise port-description

configure lldp port 1 advertise system-capabilities

configure lldp port 1 advertise management-address

configure lldp port 1 advertise vendor-specific med capabilities

configure lldp port 1 advertise vendor-specific med power-via-mdi

configure lldp port 1 advertise vendor-specific med policy application voice vlan VLAN200 dscp 46

Hi Rod,

Can you add this to your lldp configuration as well:

configure lldp port 1:6 advertise vendor-specific dot1 port-protocol-vlan-id vlan VOICE-1

Thanks,
