[Brocade] Troubleshooting - Switch Port shown wrong mode

To correct a port that has come up in the wrong mode, first use portshow <Port Number> to display more detailed information. Below listed some troubleshooting guide when you see port mode is wrong:

Disabled
Check the output from the switchShow command to determine whether or not the switch is disabled. If the port is disabled (for example, due to persistent disable or security reasons), attempt to resolve the issue and then enter the portEnable command.

Bypassed
Check the output from the switchShow command to determine whether or not the port is testing.

Loopback
Check the output from the switchShow command to determine whether or not the port is 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 fabric device, the link has come up in a wrong mode. Check the output from portLogShow or PortLogDump commands.

G_Port
The port has not come up as an E_Port or F_Port. Check the output from portLogShow or PortLogDump commands and identify the link initialization stage where the initialization procedure went wrong.

L_Port
If the opposite side is not a loop device, the link has come up in a wrong mode. Check the output from portLogShow or PortLogDump commands and identify the link initialization stage where the initialization procedure went wrong.
