Normally a NIC port on the switch is set to 'access' mode, which will strip off any VLAN tags. You'll have to move that to 'trunk' mode and configure the bridge on the linux side to also leave all VLAN tags alone.
Oh, and tell me how you've configured the linux bridge. I only know the theory, not the actual steps for doing so :-) Cheers, Hannes -- Dr. Hannes Reinecke zSeries & Storage [email protected] +49 911 74053 688 SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg GF: Markus Rex, HRB 16746 (AG Nürnberg) _______________________________________________ devel mailing list [email protected] http://www.open-fcoe.org/mailman/listinfo/devel
