6850 with multiple data vlans & one voice vlan

[millap]

Hey guys,

Myself and a colleague are having troubles getting a 6850 working with voice and data using a OmniPCX Enterprise (v7). We need to have multiple data vlans (101, 102, 103, etc) and one single voice VLAN (VLAN 2). What we're having issues with is how the IP Touch phones can be directed to the correct voice VLAN using the 6850 config.

The data VLAN's aren't a problem, they would be terminated by a AL VPN Brick 150 via an 802.1Q trunk (to allow NAT'ing of each VLAN subnet to a public address). What we can't figure is how to ensure the IP Touch phones are able to access the PCX and be assigned to the correct VLAN via the 6850.

Any help or pointers in the right direction would be greatly appreciated.

Cheers

On the IPTouch configuration you must put the VLAN ip address and the VLAN ID.

bit light on info but you need to allow those vlans on the ports (trunks) and specify the untagged (native) vlan then also specify on the trunks between switches what vlans can traverse. Also need to put the cpu/cs and gd/intip in that vlan.
You would also need to get the phones to tag with the correct vlan - do it manually first and then go to dhcp/ava if you want

best way to do this on 6850 is to use port mobility and enter full Alcatel MAC Range , then whenever you plug in a phone it is automatically put in the correct VLAN and you dont have to set any settings on the phone, much faster to deploy, i have a sample config somewhere if you need it

dear guys,any best practice guide to make port mobility on 6850.

thanks,

Hey Dallan,

Can you share your configuratino for the port mobility ?

Thank you

Frank,

Using port mobility on the OS6850 (and other OmniSwitch series) is very straight forward.

vlan 1 enable name "VLAN 1"
vlan 99 enable name "802.1x"
vlan 100 enable name "VOICE"
vlan port mobile 1/12
vlan 100 mac range 00:80:9f:00:00:00 00:80:9f:ff:ff:ff

As soon as you connect a phone on port 1/12 and the phone starts communicating (expecting that it is an IP touch with a MAC address in the range specified in above example) the vlan will be "temporarily" changed to vlan 100. I say temporarily because the port will forget this information as soon as you disconnect the phone - if a laptop gets connected to the port it will be in the default vlan (1 by default).

The "vlan mac range" rule specifies the lower MAC and higher MAC as a range - everything in between will fall into that rule.

Hope this is what you were looking for.

SWEET, yeah !

If you want to connect a PC through the phone and have the phone's traffic Q-tagged into the voice VLAN, you need to enable 'mobile tag' on the voice VLAN:

vlan 100 mobile-tag enable

If you program the phone manually with a VLAN id, or if it receives it via DHCP, the switch will automatically built a 802.1Q trunk for the Q-tagged traffice from the phone in the voice VLAN.

I'm doing this with a 6648 and 6850s, and it works. Alcatel-Lucent has a document titled AVA (Automatic VLAN Assignment) Configuration with Mobile Tag Feature on OmniSwitch 6600 in their knowledge base.

Any link to that doc "AVA (Automatic VLAN Assignment) Configuration with Mobile Tag Feature on OmniSwitch 6600" ?
