My netgear switch connects to a SonicWALL router which connects to the internet. I have created subinterfaces on the SonicWALL X0 Interface to connect that to a NetGear switch.
I have setup two VLANs in my Netgear switch.
VLAN 10 - Data - 10.10.10.x/24
VLAN 50 - Voice - 172.16.10.x/24
All ports are untagged for data and tagged for Voice vlan. and the devices are all working fine.
I face some issue with the phones and want to capture voice packets to see whats going on. I have connected a PC on port 0/2 and want to capture voice and data packets on port 0/3 on the netgear switch. Due to VLAN implementation, I only see the packets on my own port.
I followed the NetGear documentation and mirrored port 0/3 to destination port 0/2 where my monitor PC is connected, still I don't see any packets.
Please advise where to place the monitor host or any other suggestion to capture the Voice VLAN packets.
My switch and router model is below.
