Re: Duplicate Packets when importing .pcap from Cisco NAM module.

Not sure how to do it in NAM, but the principe is to only capture "incoming" (RX) packets instead of "both" incoming and outgoing. You need to do this, since every packet enters *and* leaves the VLAN, thus is captured twice if you capture both. This should be configured at the source side of the SPAN definition...

Thanks.If you're relying upon SPAN to monitor VLANs, you may want to ensure that you're doing so unidirectionally.Regards, Akhtar ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
