Hi Everyone,

I have two questions,please whoever knows the answers can help me.

1)When I configure switch for span port; monitor session 1 vlan 10-100 and monitor session destination 1 interface gig 0/1

my question is; interface gig 0/1 is destination span port  and should it configure trunk port  becuase it carries multiple vlans  or does it work without trunk mode ?

2) I want to monitor the traffic over wireshark by directly connected my computer to the destination gi0/1 port of the switch.Do I need to give

 - Span destination port should be 'left alone'  (gig 0/1) , you do not need additional commands on it ,

Hi dear,thank for your answer, what you said, I understand that I need to configure the desrination port without trunk.Well, I have to give an ip from any vlan to my computer that I connect to the Destination port to observe the traffic via wireshark and should my computer's ethernet card be in promiscous mode?

 

 

 - You can't do anything else if a port on your PC is a destination for span traffic , the port can then not be used for regular (other) network access ,

Hİ ,Thanks for your answers marce,

That's why I understand,1)I don't configure the destination span port as  trunk mode,2)I don't give any ip or configuration on my computer that I connect to destination span port for monitoring network traffic.
