Hi Deepak,

You can’t set that option with the legacy Nortel-i2004-A option. You need to use the Nortel-i2004-B option which requires UNIStim v2.3 or later firmware on the IP phones. You can find additional information on the Nortel-i2004-B option in this post. If you only have a few phones you can probably just enable bluetooth from the phone itself.

Cheers!

Hi Michael,

How do I enable bluetooth in option 128 ? Tried with bt=1

option 128 ascii “Nortel-i2004-A,10.2.224.15:4100,1,2;10.2.224.15:4100,1,2;bt,1.”

Hi Michael,

You are the Champ .. It works now !!

I was using option 191 is voice VLAN instead of data VLAN .

Thank you so much . You made my day .. Have a wonderful weekend !

Hi Deepak,

You need DHCP addresses in the data (default) VLAN with option 191 defined. You need DHCP addresses with option 128 defined in the voice VLAN.

The IP phone will issue a DHCP request in the default VLAN. If it receives a response with option 191 it will issue a DHCP release and issue a DHCP request in the voice VLAN (VLAN tag equal to the value returned in option 191). The switch port needs to be configured as untag default VLAN (allowing trunking but only tagging the non PVID ports).

Good Luck!

Hi Michael,

I am trying to connect Nortel IP Phone 1120E for full DHCP with cisco 6509 switch ( which is a DHCP server ) . But I am not able to get this Full DHCP working without configuring the Voice VLAN ID in the IP Phone settings.

option 128 ascii “Nortel-i2004-A,10.2.224.15:4100,1,2;10.2.224.15:4100,1,2.”
option 191 VLAN-A:501.

where 501 is Voice DHCP VLAN.

Any clues ?

I had a similar error where we changed the PVID of ADAC enabled ports on a 4550T-PWR stack whilst phones were plugged in. The switches went into a reboot cycle and only a hard power cycle would bring them back up properly. The resolve as you so rightly pointed out was

1. Disable ADAC on all telephony ports.
2. Change PVID on all required ports.
3. Re-Enable ADAC on ports.

Downtime was unavoidable but only lasted 3-5 minutes in total.

Best advice is to plan,plan,plan and get the settled config before putting into production.

Thanks Michael. Worked like a charm (with a little editing). For anyone else reading, it was only successful when the referrenced uoplink port in the MLT was the last numerically. Not sure if tht is teh case for everyone else.
