You would need to use private-vlan turnk functionality which is iirc not supported yet on Cisco 3400 to be able to isolated several vlans between switches. You can use just one private-vlan host or combination of UNI - NNI port type chain between the switches. downlink UNI, uplink NNI and to use proxy-ARP to take care of communication between the hosts. -- iso _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
