Reference Guide

To swap port area IDs, the port swap feature must be enabled, and both switch ports must be disabled.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the portSwapEnable port_ID command to enable the feature.
3. Enter the portDisable port_ID command on each of the source and destination ports to be swapped.
The following example disables port 1 and port 1/2.
switch:admin> portdisable 1
switch:admin> portdisable 1/2
4. Enter the portSwap port_ID1 port_ID2 command for the ports you want swapped.
The following example swaps port 1 and port 2.
switch:admin> portswap 1 2
switch:admin> portswap 1/1 2/2
5. Enter portSwapShow to verify that the port area IDs have been swapped.
A table is displayed, showing the physical port numbers and the logical area IDs for any swapped ports.
6. Enter portSwapDisable to disable the port swap feature.
Enabling a port
By default, all licensed ports are enabled. You can disable and re-enable them as necessary.
Ports that you activate with the Ports on Demand license must be enabled explicitly, as described in the Fabric OS Software Licensing
Guide .
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the appropriate command based on the current state of the port and whether it is necessary to specify a slot number:
∙ To enable a port that is disabled, enter the following command:
portEnable [slot / ]port
∙ To enable a port that is persistently disabled, enter the following command:
portCfgPersistentEnable [slot / ]port
In FMS mode, you cannot use the portCfgPersistentEnable command, so you must use the portEnable command instead.
If you change port configurations during a switch failover, the ports may become disabled. To bring the ports online, re-issue
the portEnable command after the failover is complete.
NOTE
You may also use the portCfgPersistence command while enabling or disable a port. For more information refer to the
Fabric OS Command Reference .
Disabling a port
CAUTION
If you disable the last E_Port or ISL connecting the switch to the fabric, the fabric reconfigures, the switch segments from the
fabric, and all traffic flowing between the switch and the fabric is lost.
1. Connect to the switch and log in using an account with admin permissions.
