I am using Linux with an Intel Gig quad nic.  I am capturing info from a switch, I did a vacl capturing multiple vlans with the interface.

 

switchport

 switchport capture

 switchport capture allowed vlan 184-191

 

I will try what was suggested and add the vlan rpm to my box to see if that helps.

Javier

Ethereal/Wireshark just shows the packets that the underlying capture engine provides, so usually libpcap/WinPcap.

 

Which OS are you using?

                àWindows XP, the issue is that I have not notice this problem with my Desktop but with my laptop both runnig XP. It seems it is an issue in the network card

 

What are you using to sniff the traffic between the two machines? Hub/switch?

                àIt is a HUB, I captured ok while sniffing with my Desktop.

 

BR,

Pablo

 

 

Have a nice day

I have noticed the same behavior with my gigabit nic card.  It should be capturing both directions with the line I have in, but I only see one-way traffic.

 

If anyone has something for us to try that would be great,

Javier

HI,

 

While capturing messages from two devices working at 10Mbps, the internal Gigabit card of my laptop only captures messages in one direction.

 

If I change the card properties to 10Mbps I do not receive any messages at all. Moreover If I make the capture with my desktop PC the frames are captured in both directions.

 

Any suggestion?

Thanks

 

Pablo
