We have a campus LAN with a Cat 6006 with MSFC providing layer 3\nrouting for approximately 12 VLANs, and about 40 edge switches, mostly\n2900XL and 3500XLs for client access. Most of the ports on the edge\nswitches are set to use PVLAN Edge layer 2 security (ie: "port\nprotected" or "switchport protected" ), which prevents any layer 2\ntraffic between ports in the same VLAN on each edge switch. At the\nCat6000 switch (not msfc), specific VLAN ACLs further prevent certain\nVLANs from communicating with other clients in the same group of\nVLANs. This is designed to allow for campus student access to specific\nservices while preventing peer to peer file sharing, etc, between any\nusers on this group of VLANs, and it works as designed, provided PVLAN\nedge (protected ports) are enabled on all client switch ports.\n\nWe are now trying to add some 2948G switches to this mix, and they do\nnot support PVLAN edge, according to the Cisco PVLAN compatibility\nmatrix, but do support full PVLAN modes. What is not clear to me is if\nand how we can combine both PVLAN edge switches currently in use, and\nthe Cat 2948G full PVLAN functionality on the same network, where the\n2948G will be used as edge switches for the same group of VLANs. (all\nare dynamic VLANs assigned using VMPS on the Cat6000)\n\nWe will be bench testing this next week, but if anyone has experience\nin a mixed environment like, or even just experience setting up the\n2948G or C4000/4500 as an edge switch with PVLANs, I'd appreciate any\nhelp you can offer. I'm aware of the caveat of requiring VTP mode to\nbe transparent, but not sure of other issues.\n\nThanks.
