Swapping port area IDs If a device that uses port binding is connected to a port that fails, you can use port swapping to make another physical port use the same PID as the failed port. The device can then be plugged into the new port without the need to reboot the device. Use the following procedure to swap the port area IDs of two physical switch ports. In order to swap port area IDs, the port swap feature must be enabled, and both switch ports must be disabled. The swapped area IDs for the two ports remain persistent across reboots, power cycles, and failovers. 4/256 SAN Director and DC SAN Backbone Director (short name, DC Director) only: You can swap only ports 0 through 15 on the FC4-48 and FC8-48 port blade. You cannot swap ports 16 through 47. To swap area IDs for a pair of switch ports: 1. Connect to the switch and log in as admin. 2. Enable the port swap feature: portswapenable 3.

Verify that the port area IDs have been swapped: portswapshow A table is shows the physical port numbers and the logical area IDs for any swapped ports. 6. Disable the port swap feature: portswapdisable 476 Configuring the PID format
