3560 supports pvlans no problems there but 2960 supports only private vlan edge ports (protected ports). The switches are connected with normal trunk link. My question is that if I have vlan 2001 on my 3560 as an isolated vlan and I have computers on protected ports in vlan 2001 on the 2960. Will the computers on the 2960 be able to communicate with computers on 3560? in the isolated vlan I mean. Gateway of these computers is on neither of these switches.
