Port Mirrors

[dcorrea]

Hello guys,

I have a Switch NV 1234 PoE, and I have a question: Is it possible to have 2 different monitor sessions(port mirrors)? I need to perform some wireshark captures one in my WAN port and other in my LAN port.

Regards

I believe it is possible.  You can only have one session, but you can monitor multiple ports.  For example:

You can monitor switch ports 0/1 and 0/2 using switch 0/24 to actually see the traffic.

monitor session 1 source interface switchport 0/1 both

monitor session 1 source interface switchport 0/2 both

monitor session 1 destination interface switchport 0/24

#show monitor session all

Monitor Session 1

-----------------

Source Ports:

    RX Only:   None

    TX Only:   None

    Both:      swx 0/1, swx 0/2

Destination Port: swx 0/24

You can read more on port mirroring for both CLI and GUI in the following document: Configuring Port Mirroring in AOS

I hope this helps.
