[c-nsp] pvlans and scalability

[Jimmy Stewpot]

Hi,

We have attempted this only to find that we essentially ended up with 
what appeared to be a broadcast of all unicast traffic to all 
promiscuous pvlan ports across the entire network. Unfortunately 
netbackup does not appear to handle the multiple IP addresses very well 
particularly with NDMP based backups from Filers.

Regards,

James
