Just a quick question. We are doing a single wiring run and sharing the 4620SW phone with the computer. With that we are doing VLAN Tagging and have provisioned our DHCP option 176 parameters as well. We are having a problem when we unplug our 4620 and moving it to another port that is another vlan on another card (on our CISCO switch). Problem is that it is still keeping the old VLAN tag for the voice subnet. Anybody experience this before.

we have done this before on other deployments and have had no problems. We have turned on Trunking on the interfaces in our Cisco switch gear and have programmed the port as the native data vlan as well.
 
How long are you waiting before plugging in the phone? I think the phone is trying to reconnect to a gatekeeper. You should reset all values on the phone when you plug into the new switch port. HOLD R-E-S-E-T#. Let us know. Thanks.
 
surely you don't have to reset all the values? that seems a bit intensve if you do...

can you not just do a hold/logoff (hold/564633) to move the handset?
 
You don't need to reset all the values, but you may need to set the vlan back to 0, then let it come over the the correct VLAN. Depending on your DHCP configuration.

If your VLANtest is set to 0, it will stay in it's current VLAN forever. If not, it will try for 60 seconds, then give up on that VLAN, reboot then come up in the default VLAN (eg no VLAN). Then DHCP should direct it to the correct VLAN...
 
JayNEC hit it in the head. We just finished deploying a customer in the same spot you are in. Once on a new VLAN after about 60 seconds they would reboot and work fine.
 
Thanks all. I thought that i read somewhere that you can program this value in option 176. based on what i read, the default is 60 seconds. Also, you can define a VLAN test value as well.. thx
