Hi, The mirroring port will keep all VLAN tags as they were on the original port. Page 332 ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_powerconnect/powerconnect-6248_User%27s%20Guide2_en-us.pdf   It should be able to mirror multiple VLANs.
We want to monitor our 6248's using Win 7 laptop with Wireshark We need to view all packets on all VLANs Question:       Does the destination port for mirroring have to be on VLAN 1, Trunk or can we only monitory / mirror on a per vlan basis? Thanks in advance for  your help,
