Troubleshooting Interop Mode Issues To troubleshoot interop modes, refer to the switch to switch interop guide at the following website: http://www.cisco.com/univercd/cc/td/doc/product/sn5000/mds9000/mdsint/intgd.pdf Dynamic Port VSAN Membership Issues You can dynamically assign VSAN membership to ports is achieved by assigning VSANs based on the device WWN. Dynamic port VSAN membership (DPVM) offers flexibility and eliminates the need to reconfigure the VSAN to maintain fabric topology when a host or storage device connection is moved between two switches or between ports on the same switch. It retains the configured VSAN regardless of where a device is connected or moved. OL-9285-05 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x 11-9
