  You must configure VTP to transparent mode before you can create a private VLAN. Private VLANs are configured in the context of a single switch and cannot have members on other switches. Private VLANs also carry TLVs that are not known to all types of Cisco switches. Reference: http://www.ciscopress.com/articles/ article.asp?p=29803andseqNum=6
