6. Correct the negotiation by entering the portCfgSpeed [slotnumber/]portnumber, speed_level
command if the fields in

To check for a loop initialization failure:
1. Verify the port is an L_Port.
a. Enter the switchShow command.
b. Check the comment field of the output to verify that the switch port indicates an L_Port. If a loop
device is connected to the switch, the switch port must be initialized as an L_Port.
c. Check to ensure that the port state is online; otherwise, check for link failures.
2. Verify the loop initialization if the port is not an L_Port.
a. Enter the portLogShow or portLogDump command.
b. Check argument number four for the LISA frame (0x1 1050100).

time
-------------------------------------------------
11:40:02.078
22000000,00000000,ffffffff,11050100 Received LISA frame
The LISA frame indicates that the loop initialization is complete.
3. Skip point-to-point initialization by using the portCfgLport Command.
The switch changes to point-to-point initialization after the Loop Initialization Soft Assigned (LISA) phase
of the loop initialization. This behavior sometimes causes trouble with old HBAs.
To check for a point-to-point initialization failure:
1. Enter the switchShow command to confirm that the port is active and has a module that is
synchronized.
If a fabric device or another switch is connected to the switch, the switch port must be online.
2. Enter the portLogShow or portLogDump commands.
3. Verify the event area for the port state entry is pstate. The command entry AC indicates that the port has
completed point-to-point initialization.

4. Skip over the loop initialization phase.
After becoming an active port, the port becomes an F_Port or an E_Port depending on the device on
the opposite side. If the opposite device is a fabric device, the port becomes an F_Port. If the opposite
device is another switch, the port becomes an E_Port.
If there is a problem with the fabric device, enter the portCfgGPort to force the port to try to come
up as point-to-point only.
To correct a port that has come up in the wrong mode:
1. Enter the switchShow command.
2. Check the output from the switchShow command (see
