Hi all I know this might not be strictly Wireshark-related, possibly some of you also came across this issue and might be able to help - else just tell me to go bark up another tree... :-) We're trying to capture traffic from a SPAN session on a Cisco Nexus 5020. - SPAN source (rx only) is a 4x10G Port Channel, with very little traffic. - SPAN destination is a 1x 10G port, configured as 802.1q trunk, (so that it does not strip the VLAN tags away) The NIC is a HP NC522SFP (dual 10G, PCI-E 8x) in a HP DL585-something (2x 6-core Opteron, 32GB RAM) running Windows Server 2008 64bit and the latest NIC driver available from HP (not sure about the NIC's firmware, though; as I understood, Windows drivers are soft-overlaying latest firmware anyway). It seems that this is an HP OEM product by Qlogic running their nx3 Chipset. Wireshark 1.4.0 however does get to see the VLAN tags. We've been trying to enable and disable "VLAN/Priority support" on the NIC, but there seems to be no change: Tags are not visible to Wireshark. We found http://wiki.wireshark.org/CaptureSetup/VLAN#Special_flag_settings, but the hints there don't seem applicable to this HP/Qlogic NIC. Would anyone happen to know the right conflig flag in registry or driver GUIs to make that NIC preserve the VLAN tags before handig the frame over to libpcap? best regards & thanks a lot Marc ___________________________________________________________________________ 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
