GS110TP port mirroring not working

Hi Team,

Port mirroring not working not workign on gs110TP switch.As i mentioned in the screen shot , port 6 data wants to be mirrored to port 5.

but as soon as i enable it , PC that connect to Port 5 is no more able to access to switch GUI.and PC wireshark is not gettign any packet capture , i saw the similar issue from the below link :

https://community.netgear.com/t5/Smart-Plus-Click-Switches/GS110TP-Port-Mirroring-disconnects-the-PC/td-p/1127207

as part of investigation :

1)i upgraded the image to 5.4.2.30 (latest one)

2) did the factory reset

Both didn't help to resolve the issue.

One observation i have : when 1) i enabled Tx only and 2)then rebooted the board , then i packet to (outgoing )port 6 is mirrored to port 5 and captured in my PC.

Please help on this issue.

thanks

Thanks Eriz , Hopchecn for your support.

My issue is resolved . issue was because my PC (where i used to capture the packet) dropps the vlan packets and netgear send mirrored packets with vlan tagged.
Now i used another PC where it can accpet vlan packets and able to capture mirrored tx and RX packets.

thanks again for your support
(suggestion : pls send plane packets with vlan tag removed else people may see issue with mirrored ports)

Hi njc,

Welcome to our community!

It seems that you were having problem creating a port mirroring in your GS110TP. Here is a documentation for reference. If it still doesn't work then I suggest you to create a chat / case online on NETGEAR support and please let them know the status of your switch.

    - This is perfectly normal and intended. The port you are mirroring to (also called the probe) is no longer a normal port. You will loose all connection to the network as the port no longer acts as a normal port. That is not a bug. It is a mirroring port, nothing else.
    
    "when 1) i enabled Tx only and 2)then rebooted the board , then i packet to (outgoing )port 6 is mirrored to port 5 and captured in my PC."
    - You should not need to reboot the switch in order for the mirror to start working! However, the mirror does work after the reboot it seems. I will have a quick look in the lab today, with a GS110TP to see the mirror only works after the switch is rebooted.
    
    Cheers
