I have upgraded a Tandberg E20 TE2.1.0 to TE4.1.1 (no encryption) Phone is now showing up in both Data & Voice/Video VLANS.
It appears that the Data and Voice traffic is being properly handled, due to the fact that when I SHUTDOWN the voice/video VLAN no calls can be sent or received.
Q: Do I need to worry about why the Tandberg phone is now showing up in both Data & Voice/Video VLANS?
Thanks, Scott

Hello,
I think what happens is that when the unit boots up, DHCP tries to get IP address in the native VLAN 100. After CDP discovers there's a voice VLAN, the endpoint will request DHCP address on VLAN 11. So you see MAC twice :
#sh mac address-table
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
11 0050.6004.2451 DYNAMIC Gi0/2 // Tandberg E20
100 0050.6004.2451 DYNAMIC Gi0/2
If you would clear the MAC address table, the entry for 100 will disappear [I hope].
The other entry for the connected PC is normal.
#sh mac address-table
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
100 1803.73e3.083c DYNAMIC Gi0/2 // Workstation connected to E20
We have a ddts where we would not get proper address in case of CDP automatic : CSCtx84402.
Should get fixed in TC6 release.

Hello,
the normal process would be to have the video/voice into the VLAN. Data traffic would flow when one has a PC connected to the E20 at the same time.
Can you access the E20 via root and execute some commands ?
ssh to the E20 with admin password and set the root password [here cisco used as example]
[EX90-PDIHD:~] $ tsh

Then reconnect using root and log the output to a file to capture all the data.

FYI, I will be out of the office until Saturday, I will reply back at that time. Thanks for your time.
Danny,
I have not been able to login as admin or root. The release notes state that no password is set.
Any Suggestion on how to login? I am using BitVise SSH Client 4.5
Thanks for your time, Scott

Hi Scott,
I don't understand exactly when you say you see endpoint in both the vlans.
however i believe on the switch end you have confiugred the "auxilary" vlan. that is configured the DATA and VOICE/VIDEO vlan voth.
this is for segregating the traffic and the data traffic passing through your E-20 will be via the data vlan.
and hence when you remove the other vlan from the switch or shutdown the voice/video vlan the call stops working.
Cheers

Alok,
Please see below the E20 is shown in 2 different VLANs.
Native (Data) VLAN = 100
Auxiliary (Voice) VLAN = 11
interface GigabitEthernet0/2
switchport access vlan 100
switchport mode access
switchport voice vlan 11

Danny,
I have done a "clear mac address-table dynamic" on the switch, with the same result as before.
I have installed 8 E20 (TE 4.1.1) on Cisco 3560 switches, all of the phones show up on VLAN 100 and 11.
Vlan Mac Address Type Ports
11 0050.6004.2451 DYNAMIC Gi0/2 // Tandberg E20
100 0050.6004.2451 DYNAMIC Gi0/2
Having the E20 on VLAN 100 does not seem to cause any problems for the phone or workstation, so I am going to call it good. Boss likes the new phones, therefore I like it...
Thanks for your effort.
Scott
