3. Skip point-to-point initialization by using the portCfgLport Command.

Checking 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
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
4. Skip over the loop initialization phase.

Correcting a port that has come up in the wrong mode

1. Enter the switchShow command.
2. Check the output from the switchShow command and follow the suggested actions in

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.

attempt to resolve the issue and then enter the portEnable or portCfgPersistentEnable
command.
Bypassed The port may be testing.
Loopback The port may be testing.
E_Port If the opposite side is not another switch, the link has come up in a wrong mode. Check the
output from the portLogShow or PortLogDump commands and identify the link initialization
stage where the initialization procedure went wrong.
F_Port If the opposite side of the link is a private loop device or a switch, the link has come up in a
wrong mode. Check the output from portLogShow or PortLogDump commands.
