Remote monitoring not work after divided into data vlan and voice vlan?

Hi all,

I am currently using CM8.5 and UCCX8.0, and testing the remote monitoring feature

Originally, all CAD, CSD, IP phone, CM and UCCX are in the same VLan, and the remote monitoring works great~

However, after I divided the data VLan and voice VLan in the switch

Seems the remote monitoring feature not working now ...

##############################

Voice VLan 3001 - 10.10.1.0

Data VLan 3002 - 10.10.2.0

CM - 10.10.1.10

UCCX - 10.10.1.40

IP Phone A 10.10.1.130

CAD Agent A - 10.10.2.128

* IP Phone PC port connect to CAD Agent A's Computer

IP Phone B 10.10.1.131

IP Phone C 10.10.1.132

- The Agent PC is able to ping all the device in 10.10.1.0 and 10.10.2.0

- UCCX is able to ping the Agent PC and the IP Phone A

Here are the setting of the switch

Re: Remote monitoring not work after divided into data vlan and

I see no reference to a SPAN setup in your switch configuration snippet. Are you using SPAN-based or CAD-based recording? If you're using CAD-based then the workstation NICs need to support 802.1q tagged Ethernet frames. The phone simply forwards a copy of the encapsulated voice VLAN frame down the PC Port and does not strip the 802.1q header. Many PC NICs discard tagged packets by default. You may need to Google how to get your specific NIC to accept tagged frames and pass them to the NDIS stack.

Remote monitoring not work after divided into data vlan and voic

hi,

I had followed the steps and successfully implemented the remote monitoring feature in the same VLan,

However, after I separated the VLan into Voice and Data... seems the remote mon feature doesn't work any more ...

The following phone settings must be enabled in Unified CM for desktop packet

capture to work:

■PC Port. If this is not enabled, the second network port on the back of the phone will simply not work as a network connection for the user's PC.

■PC Voice VLAN Access. Voice and data traffic can be segregated into separate VLANs in order to best use the networking resources. If the user's PC and phone are daisy-chained, and the voice and data are separated into different VLANS, the c0omputer will be a device in the data VLAN and the phone will be a device in the voice VLAN. If this option is not enabled, no voice traffic will be sent out the second network port to the daisy-chained PC.

■Span to PC Port. If this is not enabled, the phone will not forward any network traffic to the daisy-chained PC.

NOTE: Not all versions of Unified CM have all three options. Enable those that do appear on the phone device configuration.

Please use the below link for more information,

Hope it helps.

Hi Anand,

all these phone settings had configured already, and work fine in the same VLan environment

But still not working in the separated Data and Voice VLan environment ...
