Netbackup Appliance support for VLAN Tagging?

Hi, Let me know if you have any information that support this statment.

We are trying to create a BIG (10GbE) pipe (4 Interfaces) conecting the appliance to a cisco NEXUS in a customer data center, the customer has so many VLAN's an they were asking us if we can use VLAN tagging to transport our Backup trafic as well the iSCSI traffic comming from Vmware. 

If you have other idea to do that let me know, We are configuring 4 appliances each of them with four (4) 10GbE SFP+ ports,

Thanks,
